Pros & Cons
COROS VERTIX 2S (50mm)
Pros

- +Titanium bezel, 10 ATM rating and a two-year warranty with no subscription anywhere
Cons
- −The famous 118 h is standard single-band GPS. Switch to the dual-frequency mode you bought it for and it is 43 h — a 63% cut
- −COROS' own figures disagree on smartwatch life: the spec sheet says 40 days, the current product page says 36
- −85 g and 50.3 mm wide with a 16.3 mm case — genuinely large on a smaller wrist
- −No ANT+, no NFC payments, no streaming music
- −MIP screen is dim in low light next to the AMOLED watches at this price

- −No music storage of any kind on a $599 watch
- −Only about 10-12 routes can be stored in practice despite 32 GB, and turn-by-turn needs manual enabling for imported routes
- −Real-world dual-frequency runtime with always-on and navigation running measured about 50 h, not 65 h
- −Bluetooth only — no ANT+ sensor support
