Best Cheap Smartwatches Under $100 (2026)
What are the best cheap smartwatches under $100 in 2026?
TL;DR
Top pick: Amazfit Active 2 ($99.99, 44mm GPS) — GPS + NFC + offline music + 10-day battery, the consensus best under $100.
Best value: Amazfit Bip 6 ($79.00, 46mm GPS) — 1.97" AMOLED and 14-day battery for $21 less.
Best budget: Xiaomi Redmi Watch 5 Active ($40.39) — 18-day battery and a 2.0" screen for ~$40. [src1, src2, src5]
Summary
The sub-$100 smartwatch market in 2026 has matured dramatically: budget wearables now ship built-in (and, at the top of the bracket, dual-band) GPS, AMOLED displays, Bluetooth calling, and multi-day battery life that cost $200+ two years ago. Amazfit still anchors the category. The Amazfit Active 2 ($99.99, 44mm GPS model) delivers 10-day battery, GPS with turn-by-turn navigation, NFC payments and offline music in a stainless steel body, and remains the consensus pick under $100. [src1, src2, src3]
For a larger screen and longer battery, the Amazfit Bip 6 ($79.00, 46mm) pairs a 1.97-inch AMOLED with 14-day battery and Bluetooth calling. The newer CMF Watch 3 Pro ($74.92 in Light Grey; the Dark Grey and Orange colourways sell for ~$99) is the accuracy story of 2026 — dual-frequency L1+L5 GPS that locks in seconds and a four-channel heart-rate sensor, at a price no dual-band watch has hit before. The Fitbit Inspire 3 ($79.95) is the pick for people who want a health platform rather than a gadget: it is the only device in this comparison with an FDA-cleared function (PPG irregular-heart-rhythm notifications, K212372, April 2022). [src4, src8, src9, src11]
Below $60 the honest trade is features for verification. The Xiaomi Smart Band 10 ($51.80) is the only sub-$55 pick with a 5ATM rating and real swim tracking, the CMF Watch Pro 2 ($55.06) has fallen ~20% since spring, and the Xiaomi Redmi Watch 5 Active ($40.39) buys 18-day battery and the biggest screen here. Under $35 nothing has been independently lab-tested — the TOZO S3 ($29.99) works, but expect no third-party health-platform sync and no accuracy data. This bracket also churns hard: the Wyze Watch 47 has been discontinued, and Samsung's US Galaxy Fit3 listing has read "currently unavailable" since at least July 2026, so both were dropped from this card.

Best for Each Use Case
Best Overall: Amazfit Active 2 ($99.99, 44mm GPS) — Check price
Consensus pick across Tom's Guide, TechRadar, and Wareable. The Active 2 packs features that rival $200+ watches: built-in GPS with offline maps and turn-by-turn directions, NFC payments via Zepp Pay, offline music storage, a 1.32-inch AMOLED display at 2,000 nits brightness, and 164 sport modes with AI running coaching. The stainless steel body looks far more premium than its price suggests, and its 5ATM rating makes it pool-safe. Heart rate and sleep tracking are good enough for daily trend-watching — not for clinical use. Zepp OS is proprietary: no third-party app store. [src1, src2, src3]
Best Battery + Large Display: Amazfit Bip 6 ($79.00, 46mm GPS) — Check price
The Bip 6 offers the best screen-to-price ratio in this category: a 1.97-inch AMOLED paired with a claimed 14-day battery (about 12 days in typical use). It includes Bluetooth calling, built-in GPS with five satellite systems, 140+ workout modes, and an AI voice assistant, and it is rated 5ATM for swimming. At $79.00 it undercuts the Active 2 by $21 while offering a much larger display. Trade-offs: aluminium rather than stainless steel, and no NFC payments. [src1, src4]
Best GPS Accuracy: CMF Watch 3 Pro ($74.92, Light Grey) — Check price
Nothing's 2026 budget flagship is the first sub-$80 watch with dual-frequency L1+L5, five-system GPS, and reviewers report it locks position within seconds and tracks routes accurately enough to leave the phone at home. A new four-channel heart-rate sensor improves consistency across skin tones and workout intensities, and Wareable calls it the best-looking wearable under $100. GSMArena measured about 7 days of real-world battery against the 13-day claim with always-on display off. Two hard limits: it is IP68 only and CMF does not recommend pool use, and there is no NFC payment or third-party app support. Price is colourway-dependent — Light Grey is $74.92 while Dark Grey and Orange sell around $99. [src8, src9]
Best Health Platform: Fitbit Inspire 3 ($79.95) — Check price
The Inspire 3 is the pick for people who want health analysis rather than gadget specs: Sleep Score, Active Zone Minutes, stress tools, and the deepest history/insight platform in this price bracket. It is also the only device in this comparison with a regulatory clearance — Fitbit's PPG irregular-heart-rhythm notification algorithm was FDA-cleared in April 2022 (K212372) and the Inspire 3 is on the supported-device list. That is a screening notification, not a diagnosis. It has no built-in GPS (connected GPS via the phone only) and no Bluetooth calling, works with both iPhone and Android, and is rated 5ATM. Note the platform move: Fitbit Premium is now Google Health Premium at $9.99/month or $99.99/year, with three months included in the box; core steps, heart rate and sleep stages stay free. It has recently street-priced between $66 and $80 — check before buying. [src5, src7, src11]
Best for Swimming: Xiaomi Smart Band 10 ($51.80, Global Version) — Check price
The cheapest pick here that is genuinely swim-rated. Its 5ATM rating covers pool use, and Xiaomi added a nine-axis sensor with stroke recognition, lap counting and underwater heart-rate sampling that the Band 9 lacked. The 1.72-inch AMOLED is bright, battery runs to a claimed 21 days (7-10 days realistic with always-on brightness), and it charges in about an hour. Trade-offs: no built-in GPS, so outdoor route tracking needs the phone; the US listing is a Global Version import, so warranty handling runs through the seller rather than a US Xiaomi service channel. Optical wrist heart rate is unreliable under water for anyone — a chest strap remains the honest answer for accurate in-water HR. [src10]
Best Design Value Under $60: CMF Watch Pro 2 ($55.06) — Check price
Nothing's earlier sub-brand watch keeps the trick its successor dropped: swappable bezels. It has single-band GPS, Bluetooth calling with AI noise reduction, heart rate and SpO2 monitoring, and 120+ sport modes behind an 11-day battery and a 1.32-inch AMOLED. It has fallen about 20% since spring to $55.06, which restores the price advantage it had lost — it is now $20 below the Watch 3 Pro rather than $10. Same water caveat as its successor: IP68 means splash and rain, not swimming. [src2, src5]
Best Ultra-Long Battery: Xiaomi Redmi Watch 5 Active ($40.39) — Check price
At a claimed 18 days from a 470mAh cell, the Redmi Watch 5 Active outlasts every other watch here by a wide margin, and its 2.0-inch LCD is the largest display in the comparison. Bluetooth calling, 140+ workout modes and a 5ATM rating round out the package. Trade-offs: no built-in GPS, LCD rather than AMOLED, and heart-rate accuracy during hard exercise is inconsistent — treat its workout HR as indicative only. [src2, src5]
Cheapest That Still Works: TOZO S3 ($29.99) — Check price
At $29.99 the TOZO S3 (sold as TOZO's "2026 New Upgraded" watch) delivers a 1.83-inch colour LCD, Bluetooth calling through a built-in mic and speaker, step/sleep/heart-rate tracking and a claimed 10-day battery. Buy it only if $30 is a hard ceiling, and know what you are giving up: no major outlet has lab-tested this model, so there is no independent accuracy data; there is no GPS at all; data lives in the TOZO Health app with no Apple Health, Google Health or Samsung Health sync; and the listing's "IP68 waterproof (50m)" wording is marketing, not a swim rating — IP68 is splash and rain only, so keep it out of the pool. [src2, src5]
Head-to-Head Comparisons
Amazfit Active 2 vs Amazfit Bip 6
Both offer built-in GPS and Bluetooth calling, but the Active 2 ($99.99, 44mm) wins on build (stainless steel vs aluminium) and NFC payments, while the Bip 6 ($79.00, 46mm) wins on display size (1.97" vs 1.32") and battery (14 vs 10 days claimed). The Active 2's 164 sport modes edge out the Bip 6's 140+. Both are 5ATM, so both are pool-safe. [src1, src3, src4]
Pick Active 2 if: you want NFC payments, offline music, a stainless steel finish, or AI running-coach features.
Pick Bip 6 if: you want a larger display, longer battery life, or the lowest price for built-in GPS.
Amazfit Bip 6 vs CMF Watch 3 Pro
The two best GPS watches under $80. The Bip 6 ($79.00) wins on display size (1.97" vs 1.43"), battery (14 vs 13 days claimed, and GSMArena measured only ~7 days on the CMF), 5ATM swim rating, and Zepp ecosystem maturity. The CMF Watch 3 Pro ($74.92 in Light Grey) wins decisively on GPS: dual-frequency L1+L5 versus the Bip 6's single-band receiver, which matters for anyone running in cities or under tree cover. [src4, src8, src9]
Pick Bip 6 if: you swim, want the biggest screen, or want the longest verified battery.
Pick CMF Watch 3 Pro if: outdoor route accuracy is the point and you never swim with a watch.
CMF Watch 3 Pro vs CMF Watch Pro 2
Same brand, one generation apart, and $20 apart at today's prices ($74.92 vs $55.06). The Watch 3 Pro adds dual-band GPS, a four-channel heart-rate sensor, a larger 1.43-inch AMOLED and a metal body. The Watch Pro 2 keeps the swappable bezels that the 3 Pro dropped, and at $55.06 it is now the cheapest watch here with any built-in GPS. Neither should go in a pool — both are IP68 only. [src2, src5, src8, src9]
Pick Watch 3 Pro if: GPS accuracy and heart-rate consistency justify the extra $20.
Pick Watch Pro 2 if: you want built-in GPS and customisable looks for the lowest possible price.
Fitbit Inspire 3 vs Xiaomi Smart Band 10
Two slim bands, $28 apart ($79.95 vs $51.80). The Inspire 3 wins on platform depth — Sleep Score, Active Zone Minutes, stress tools — and it is the only pick here with an FDA-cleared function (irregular-rhythm notifications). The Smart Band 10 wins on raw hardware for the money: a bigger, brighter 1.72-inch AMOLED, a claimed 21-day battery against 10, and real swim metrics (stroke recognition, lap counting) on the same 5ATM rating. Recurring cost differs too: the Inspire 3's deeper analytics sit behind Google Health Premium ($9.99/month or $99.99/year) after the three included months, while Xiaomi's Mi Fitness app charges nothing. [src5, src10, src11]
Pick Inspire 3 if: you want health insight, US warranty support, and rhythm-notification screening.
Pick Smart Band 10 if: you swim, want the longest battery, and want no subscription at all.
Xiaomi Redmi Watch 5 Active vs Amazfit Bip 5 Unity
Both are big-screen, no-built-in-GPS watches, now $19.56 apart ($40.39 vs $59.95 — the Bip 5 Unity has risen roughly 20% since spring). The Redmi Watch 5 Active wins on display size (2.0" vs 1.91"), battery (18 vs 11 days) and price. The Bip 5 Unity wins on display quality (its 1.91-inch panel is sharper than the Redmi's LCD), a metal-framed build, and the Zepp app ecosystem with 70+ downloadable mini-apps. [src2, src5]
Pick Redmi Watch 5 Active if: maximum battery, the largest screen and the lowest price matter most.
Pick Bip 5 Unity if: you want the better panel, a more premium build and the broader Zepp ecosystem — and the $20 premium is worth it to you.
Decision Logic
If budget < $45
→ Xiaomi Redmi Watch 5 Active ($40.39) for the best feature set under $45, or the TOZO S3 ($29.99) only if $30 is a hard ceiling. Below $45 expect no built-in GPS, no independent accuracy testing on the cheapest models, and no third-party health-platform sync on TOZO. [src2, src5]
If you swim or want pool tracking
→ Xiaomi Smart Band 10 ($51.80) for the cheapest real swim tracking, or Amazfit Bip 6 ($79.00) / Amazfit Active 2 ($99.99) for a full watch. Require 5ATM. Do NOT buy the CMF Watch 3 Pro, CMF Watch Pro 2 or TOZO S3 for swimming — all three are IP68, which is splash and rain only, and CMF explicitly advises against pool use. Wrist optical HR is unreliable submerged on every model here; use a chest strap for in-water heart rate. [src8, src9, src10]
If primary use is outdoor running or route tracking
→ CMF Watch 3 Pro ($74.92) for dual-band L1+L5 GPS accuracy, or Amazfit Active 2 ($99.99) if you also want offline maps and turn-by-turn navigation. Avoid the connected-GPS-only models (Inspire 3, Smart Band 10, Redmi Watch 5 Active, Bip 5 Unity) — they need the phone in your pocket to record a route. [src1, src3, src8, src9]
If you want health insight rather than gadget specs
→ Fitbit Inspire 3 ($79.95). Deepest analysis platform in this bracket and the only pick with an FDA-cleared function (PPG irregular-rhythm notifications, K212372). Budget $9.99/month or $99.99/year for Google Health Premium after the three included months if you want the advanced analytics; core tracking stays free. [src5, src7, src11]
If user has an iPhone
→ All nine picks pair with iOS, but the Amazfit Active 2, Amazfit Bip 6 and Fitbit Inspire 3 have the most complete iPhone support (notifications, Apple Health sync on Zepp and Fitbit). The TOZO S3 syncs only to its own app, so it never reaches Apple Health. [src1, src5]
If battery life is the top priority
→ Xiaomi Smart Band 10 (21 days claimed) or Xiaomi Redmi Watch 5 Active (18 days). Both outlast every watch here by a week or more. Halve any claim if you enable the always-on display, and expect GPS-heavy weeks to cut watch battery by 30-60%. [src2, src5, src10]
If you need Wear OS, an app store, or LTE
→ Skip this unit entirely — nothing under $100 offers them. See fitness/wearables/smartwatches/2026 or fitness/wearables/smartwatches-for-android/2026. [src1, src6]
Default recommendation
→ Amazfit Active 2 ($99.99). Best balance of features, build quality, water rating and battery. GPS, NFC, offline music and 10-day battery cover most use cases, and it discounts to roughly $85 during Prime Day and seasonal sales. If $80 is the ceiling, the Amazfit Bip 6 ($79.00) loses only NFC and the steel case. [src1, src2, src3]
Key Market Trends (2026)
- Dual-band GPS has arrived under $80: The CMF Watch 3 Pro ($74.92) ships L1+L5 five-system GNSS, a spec that was $300+ territory in 2024, and reviewers confirm fast locks and usable route accuracy. [src8, src9]
- Bluetooth calling is now standard under $100: Nearly every sub-$100 smartwatch in 2026 takes and makes calls over Bluetooth (within ~10m of the phone), a feature that cost $150+ in 2024. [src1, src2]
- Budget churn is a real buying risk: The Wyze Watch 47 has been discontinued, and Samsung's US Galaxy Fit3 listing has read "currently unavailable" since at least July 2026. Cheap-watch model lines are retired quickly, and app support follows the hardware — factor vendor going-concern risk into anything under $50. [src2, src5]
- Subscription models are diverging: Amazfit made Zepp Aura and Zepp Fitness free for life, while Fitbit Premium became Google Health Premium at $9.99/month or $99.99/year (up from $79.99). At this price point the software bill can exceed the hardware bill within a year. [src11]
- The budget bracket is growing fast: IDC put affordable smartwatch growth at 47% in 2025, with Amazfit leading; leaks point to an Amazfit Active 3 with triple-band GPS in late 2026, which should push current models down again. [src1, src2, src5]
- Health tracking accuracy gap persists: Features converge faster than sensors. Independent step-count testing shows roughly 2-5% error on Amazfit and Fitbit hardware versus 8-15% on the cheapest white-label watches, and no sub-$35 model in this bracket has been lab-tested at all. [src5, src7]
Important Caveats
- This is not medical advice, and none of these devices is diagnostic. Optical heart rate, SpO2 and sleep staging on consumer wearables are trend indicators, not clinical measurements. The single exception in this lineup is Fitbit's PPG irregular-heart-rhythm notification feature, FDA-cleared in April 2022 (K212372) and supported on the Inspire 3 — and even that is a screening alert, not a diagnosis. See a clinician for any persistent symptom. [src11]
- Prices are live Amazon US prices captured on 2026-08-09 for the exact configuration named in the table. Colourway changes the price materially on the CMF Watch 3 Pro (Light Grey $74.92 vs ~$99 for Dark Grey and Orange), and case size changes the listing on the Amazfit models.
- Water ratings are not interchangeable. 5ATM is pool-safe; IP68 is splash and rain only. Any listing claiming "IP68 waterproof 50m" (the TOZO S3's wording) is conflating the two — do not swim in an IP68 watch. Ratings also assume intact seals: avoid hot water, saunas, and pressing buttons underwater.
- Samsung Galaxy Fit3, TOZO S6 and Wyze Watch 47 were removed from this card on 2026-08-09: all three read "currently unavailable" on Amazon US, the Wyze Watch 47 has been discontinued outright, and Samsung does not sell the Fit3 through its own US store.
- The Xiaomi picks are Global Version imports rather than US-channel stock; warranty and support run through the Amazon seller, not a US Xiaomi service centre.
- Battery figures are manufacturer claims under typical use. Independent testing came in materially lower on the CMF Watch 3 Pro (~7 days measured against 13 claimed), and always-on display, heavy GPS use and Bluetooth calling cut any of these by 30-60%.
- No sub-$100 smartwatch matches an Apple Watch or Galaxy Watch for app ecosystem, voice assistant quality or notification handling, and none supports cellular/LTE.
