In reply to Euan McKendrick:

Much like you I can't stand climbing with a watch on, but I think that's why COROS have cracked it, as the carabiner/heart rate monitor allow you to carry it elsewhere - either on your harness or in a pocket.
If there were to be a caveat to that it's that it comes at a price, although in the context of top end 'sports wearables' the Vertix 2S is actually it's in the same ballpark as all the other big players:
COROS Vertix 2S £599
Suunto Vertical £545-725
Garmin Fenix 7S Pro - £519-739
The written review will be published shortly, where I'll go into more detail on its relevance to hillwalkers/runners.
