How can you choose to be sponsored by a company that makes a sports watch lacking such a basic feature? The only way to get RHR is to hit a few buttons and the dial and manually take an RHR reading every morning immediately after waking up. Else you went have any RHR reading for that day.
Like it’s the 20th century. Every other watch gives you a decent estimate if you just wear it all day and don’t think about it. Stupid Coros.
