Polar FT7 Training Heart Rate Monitor Watch w/ WearLink Coded Chest Strap

Description

Polar FT7 Training Heart Rate Monitor Watch w/ WearLink Coded Chest Strap.
These two items were purchased together, so I’m assuming they’re compatible, but don’t know for sure.
I don’t want to open the chest strap to verify.
I’m hoping that if you’re shopping for these items, you know more than me. If you have any questions, I’ll certainly try to answer them for you.
Watch has brand new battery.
