In reply to bouldery bits:

Interesting and good to know in case I start getting tempted away from Garmin.
I've used Garmin's customer service twice (both slightly cheeky out of warranty queries) and was not disappointed. They were responsive and helpful. On one of the occasions they sent me a reconditioned replacement watch when they technically didn't have to, so overall a thumbs up for Garmin customer service (and their watches!)
