COROS PACE 4 Pro: what it gives up
- No contactless payments; COROS states payment is not supported
- Costs about the same as the APEX 4 46 mm, which has a longer MIP battery and better outdoor durability
- 5 ATM rating, below the 10 ATM of the VERTIX line
- No third-party app store, so smartwatch functions stop at notifications and media control
COROS PACE 4: what it gives up
- 4GB storage leaves far less room for maps and music than the 32GB PACE 4 Pro
- No speaker, so no calls or spoken alerts as on the PACE 4 Pro and APEX 4
- No contactless payments
- Mineral glass instead of sapphire
- Notifications only; no app store or message replies listed
