Update 20 March 2018: Hi. I have switched to a new tracker and won't be using the Vivoactive HR anymore. Hence I won't be updating this watch face. But I will leave it up here for those who still want to use it but won't be able to assist in any queries. Thanks for your support.
*****************************
NOTE: I have only tested this with the Garmin Connect app for the iPhone. There is an issue where configuration may cause some issues with Android's Connect app. Though I have addressed it in the coding for this watchface, I have not been able to test it on an Android smart phone as I do not have one.

This watch face displays the time in huge fonts on two separate lines. The colours of the hour and minute can be configured separately via the Garmin Connect app. Depending on the time format set on your watch, it will display either 12 or 24 hours.

Seconds is displayed on the right of the minutes when in high power mode (when you raise your wrist to look at it). The way the watch is built, developers cannot get the seconds to show constantly as this will drain the battery.

The configurable date is displayed at the top and on the extreme right of that is the battery strength indicator.

The configurable data field is displayed at the bottom. And on the extreme right of that is the Bluetooth connection indicator, alarm and phone notification indicator (which will appear over the Bluetooth indicator).

When configuring the watch face, please note that changes will only be effected on your watch display when you raise your wrist to look at it (high power mode) or when the minute change (the watch refreshes once every minute).
