Bluetooth compatible HRM watches?

i don’t have an ant dongle so I just sync everything over Bluetooth.  Does anyone have any recommendations for a watch type hrm that will sync with Zwift over Bluetooth?

Wahoo Tickr is a very good chest strap HRM that transmits in both ANT+ and BLE, wrist based HRM are accurate enough yet for training in my opinion.

By far the best zwift-related purchase I made in a while was the Scosche Rythm+ heart rate strap. Worn on the forearm so it is much more comfortable than any chest strap. Check the DCRainmaker review. They’re also a good company - I went to buy a replacement strap and they sent me one for free.
