the most expensive watches in the world are only rated to 3ATM, water resistance has nothing to do with craftsmanship. Why would you wear a dress watch in the shower anyway? you can get 20ATM waterproof watches for under 100USD.
I guess, being new to the watch-game, my understanding of craftsmanship differs from yours.
technically there is little to no reason why only diver watches can hit the shower and not these nice business watches (I'm not talking about diving, mind you).
To be honest i was quite shocked that these watches can't see water. Like you just said, if a 100USD watch can take it ...
A deep inner voice prevents me from buying a watch that's not water resistant, i can't explain it but it's true. This got me to really look at diver watches.
It's really strange how a watchtyp i always thought looked ugly became one of my favorite.
Anyway, since i have really thin wrists, a tight budget and don't really wan't an automatic (even though the technical marvel behind automatics is really appreciated by me, i just don't see how cheap automatics can keep time accurately), i got a Citizen Promaster BN0000-04H (quarz clock/steel unibody/solar powered).
The regular wristband is not only ugly, but uncomfortable as hell - so i replaced it with a natostrap.
I like the sporty, slightly vintage look.
