tpach78 Actually, I think you would be surprised Torsten… 👁️
Earlier this year, while on holiday in North Norfolk, I wore my F-91W 24hrs a day for the entire holiday, showers, bathing, washing, rain shine the lot and not once did I worry about the watch… 👍🏻
There is a great Utoober who has a large number of F-91Ws and he swears by their waterproof-ability, he swims a lot and never once have any of his watches let him down. The WR (Water Resistant) rating is very much understated and doing 2-3metres underwater will not be an issue, I’m sure… ✅ His Channel is under the name ‘Accoutrements’ and well worth a watch… 👌🏻
In any event, they are so inexpensive it really has to be worth the risk - should it, by any chance, fail a replacement will not hurt much at all… 😬
