Been looking at HR watches for a Christmas gift and while White wasnt top of the shopping list, the price difference may have swayed it.
Gets decent reviews compared the Fitbit Charge 2 and Garmin Vivoactive HR but with the addition of GPS on device
Specs and accurate description of the device can be found on the Garmin website: https://buy.garmin.com/en-GB/GB/prod552962.html
£166-£169 on amazon for the other colours
