Details
COROS PACE 4:
Uses standard 22mm quick-release bands. This means you can use almost any standard COROS 22mm band (or third-party 22mm quick-release bands).
COROS PACE Pro:
While it technically uses a 22mm width, it features a proprietary push-lever quick-release design unique to the Pro model. Standard quick-release pins will not fit securely, so you need to look specifically for the PACE Pro designated "Textured" bands.
The COROS APEX 2 and APEX 2 Pro use different band widths from each other.
Unlike the PACE series, they use standard, traditional quick-release bands:
COROS APEX 2:
Uses 20mm standard quick-release bands.
COROS APEX 2 Pro:
Uses 22mm standard quick-release bands.
Compatibility Notes:
APEX 2 Pro: Because it uses a standard 22mm quick-release system, it is compatible with the PACE 4 bands. However, it is not compatible with the PACE Pro bands due to the PACE Pro's unique proprietary push-lever system.
APEX 2: Its 20mm width is a standalone size compared to the other watches you've asked about, meaning it cannot share bands with the PACE 4, PACE Pro, or APEX 2 Pro.
