From the post
Purchased these as backups to the watches I had at the time, but no longer have use.
Asking $20 each, or $30 for the pair.
Coros is 22mm, and listed compatibility is for PACE 4, PACE 3, PACE Pro, APEX 4 42mm, APEX 2 Pro, APEX Pro, APEX 46mm. This color is no longer sold.
Garmin is 20mm, and listed comparability is really voluminous, see this link at bottom.
Both are unused and unopened.
Thanks!
