How do I override the built in heart rate monitor with a bluetooth chest strap in the Workout app?

The watch monitor is not working well and I have paired a bluetooth chest strap but the App is still fruitlessly searching for a heart rate from the watch.

Comparing internal AppleWatch heart rate sensors with chest strap bluetooth chest strap


I have an iPhone 6 and an AppleWatch. When a compatible Bluetooth chest strap HRM (i.e., Polar H7 or Wahoo-Tickr) is properly connected to the iPhone, the following will be seen: iPhone Settings>Bluetooth>here you see the name of the Bluetooth chest strap HRM as "Connected".


Open the iPhone App, "Health", and it will list the Bluetooth chest strap when "Sources" is clicked along the bottom of the screen. When the name of the bluetooth chest strap is clicked, "Update Health Data" can be activated.


On the AppleWatch, open the app, "Workout". Now choose the activity and start. By swiping the watch-face to the side,"Heart Rate" can be viewed during the workout. The questions is: Does the watch know to read the Bluetooth chest monitor? Or, use the its own internal watch heart rate sensors? Or, both?


Open a running App like "Endomondo" on your iPhone (assume it is connected properly to the same Bluetooth chest strap HRM). Take a run and compare the Heart Rate from your AppleWatch (running "Workout") with the Heart Rate you see on your iPhone (running "Endomondo".) If both are using the same information from the Bluetooth chest strap HRM, identical readings would be seen. But, that is not the case!


So, how does the AppleWatch manage this "trade-off" of its own internal HRM sensors when a Bluetooth Chest strap HRM is in the mix?
