Selling on behalf of a friend, this was his 40th Birthday present from his wife, which i think he wore for the first year before deciding it was too bling for him and he went back to his running watch and wearable tech. (I have explained to him that it was a gift and he might well regret selling this, but alas he wants to go forth and get it selt!)
Anyway, resident watch geek a.k.a The Rolfe is listing it this week on TZ, so deal to be done for a SE'r for a quick hassle free sale.
