100 metres is enough. Mostly
By Tom Hargreaves, Falmouth, Cornwall ยท
People get very worked up about water resistance numbers. 100 m on the Divers Sixty-Five is plenty for snorkelling, swimming, and recreational diving, which stops at 40 metres anyway. Where I'd hesitate is jumping off a boat with it repeatedly, or using it in the surf where water hits it hard. The rating's a lab number, not a depth limit, but it's still the lowest in this lot.
Otherwise, it's a lovely watch. 40 mm, 12.8 mm thick, a domed crystal, blue dial, vintage-style numerals from the 1965 original. Oris 733 inside, which is a Sellita, 38 hours. $2,100 to $2,400.
This is the one I'd wear to the pub. It's not the one I'd wear to work.
Grumble: the domed crystal looks great and catches reflections like a car windscreen in low sun. On a grey day underwater that's less of an issue, but on the beach it can be a pain to read.
