The cheapest watch here that has built-in GPS and a 5ATM swim rating at the same time — and it carries the biggest AMOLED and the longest battery of any GPS watch in the comparison.

■ The catch — co-equal billing, always
Aluminium, no NFC, and a single-band GPS receiver. The $21 you save against the Active 2 buys aluminium instead of stainless steel, no Zepp Pay, and a single-frequency receiver that wanders among tall buildings and under tree cover — exactly where the $74.92 CMF's dual-band L1+L5 pulls ahead. Bluetooth calling also dies the moment you walk away from the phone.

Traps — this verdict avoids
Why the Amazfit Bip 6 is right for you
It avoids every trap below — and for just me, under $80, it is the pick because it delivers:
"IP68 waterproof 50m" is not a swim rating
Two different scales get printed as one number. 5ATM is pool-safe; IP68 is splash and rain only — and CMF explicitly tells you not to swim in its IP68 watches. The TOZO S3 listing says "IP68 waterproof (50m)", which conflates the two. If you swim, the only picks that qualify are the 5ATM ones: Active 2, Bip 6, Bip 5 Unity, Smart Band 10, Redmi Watch 5 Active and the Inspire 3.
"GPS" on the box is usually your phone's GPS
Connected GPS borrows the phone in your pocket; built-in GPS records a route on its own. Four of the nine watches here — Inspire 3, Smart Band 10, Redmi Watch 5 Active and Bip 5 Unity — are connected-GPS only, and leave your run untracked if you go out without the phone. Only the Active 2, Bip 6, CMF Watch 3 Pro and CMF Watch Pro 2 have a real receiver.
The colourway is the SKU
Same watch, different listing, different price. The CMF Watch 3 Pro is $74.92 in Light Grey and about $99 in Dark Grey or Orange — a 32% premium for paint. Case size does the same thing to the Amazfit models: the 44mm and 46mm variants are separate listings. Always check that the price you saw belongs to the colour and size in the cart.
