Vostok| Amphibia 420059 Scuba Dude Automatic Self-Winding Diver Wrist Watch | 5-Stripe Strap

I would not purchase from this seller. I received my watch and finished setting the time. It works/runs fairly well, but loses about 75 seconds each day which requires a reset after about a week. That's standard for most Vostok watches due to their movement which is not why I'm giving this a single star.I'm giving this 1 star because I took it to the beach and went swimming (less than 5 meters) and the watch crown filled with water. I tested and inspected the watch beforehand with some water and everything was fine. Looks like it wasn't properly sealed...
