GPS Running Watches / COROS
COROS VERTIX 2S (50mm)
118 hours of GPS — as long as you never turn the dual-frequency mode on.
Overall score 7.6/10
Pros
- + 118 h of GPS is the longest single-charge figure in this comparison by a wide margin
- + Free global offline topo maps with turn-by-turn in 32 GB, plus MP3 music storage
- + MIP and sapphire mean the battery claims survive the way you actually use the watch
- + 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
COROS VERTIX 2S (50mm) review: what the specs say
118 hours of GPS — as long as you never turn the dual-frequency mode on. At $699, COROS's 2024 model sits in the middle of the range — the GPS Running Watches we compare run from $249 to $1,199.99. It scores 7.6/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is GPS Accuracy at 8.4/10 — trace quality in cities and under tree cover — multiband L1+L5 hardware plus what independent testers measured in the real world.. The weakest is Display at 6.6/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: 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; and COROS' own figures disagree on smartwatch life: the spec sheet says 40 days, the current product page says 36. Every specification on this page comes from COROS's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
