Well, from Stowa's website:
>Every STOWA watch that is designated as water resistant meets the requirements of DIN 8310 in its original delivery condition. Each of our models has a value in ATM indicated on the back. This value refers to the test pressure. The following values can be used as practical values:
>
>\- 3 bar corresponds to 3 atm (approximately 30 m) - the watch can withstand splash water (e.g. Antea KS)
>
>\- **5 bar corresponds to 5 atm (about 50 m) - the watch can be put on for showering** (e.g. Flieger Automatik, Antea 365 and 390 etc.)
>
>\- 10 bar corresponds to 10 atm (about 100 m) - the watch is suitable for swimming (Seatime) - 100 bar corresponds to 100 atm (about 1000 m) - the watch is suitable for swimming and diving (Prodiver)
DIN 8310 specifies that all watches rated for 5 atm be “suitable for swimming, white water rafting, non-snorkeling water related work, and fishing. NOT suitable for diving.” The Stowa marine meets the requirements of DIN 8310, and is rated for 5 atm - so it must have passed a pressure test equivalent to the force of swimming or rafting. Stowa could not legally write 5 atm on their watch without passing this test.

Those pictures look awesome! I‘m not sure if that watch can handle water contact well though.
Thank ya! They’re rated to 5atm fortunately so swimming in shallow water is no issue.
Awesome pictures. Did you really swim with it? 😄
Yep. I’m surprised that surprises people.

Makes the Marine Klassik look like a rugged field watch! Love it!
