5 ATM is 50 meters...which is 165 feet. Would you like to amend that post?
I meant to say that and the statements are exclusive of each other.
What I’m about to say assumes the watch is functioning correctly and its features are set correctly.
When they pressure test a watch, it’s in a chamber sitting and a vacuum applies pressure. When swimming the forces from diving in water or moving your arms can apply pressures in excess of 5 ATM. This is why non-screw down crown watches, w/5 ATM testing, suggest you don’t swim in them. It’s not to say you can’t submerse them or shower in them, just limit the forces of moving through water. There is also the chance that the crown is not pushed in all the way and or the seal is old.
As an example, I wouldn’t swim in a Hamilton Khaki Field. Your luck will eventually run out.
3 ATM watches are a hand washing affair only.
All of this has less to do with the depth rating and more to do with screw down crown. This is why I said anything w/screw down crown and 150+ feet rating is fine for swimming.
I am a diver. More than a recreational diver. Since the advent of wrist based dive computers most divers don’t wear dive watches past nostalgia. The hardest thing on a dive watch, when your diving, is the dive boat. Your watch gets beat to shit, as the boat moves, you move and your gear moves. Expensive watches don‘t fare well. I have also seen my share of expensive watch get lost as people didn’t understand pressure and how the nice metal band, w/it‘s divers extension, will become so loose as pressure is applied to your body/wetsuit that the watch slips right off your arm.
Anywho, 200m screw down crown watches are great for swimming, snorkeling and basic recreational scuba.
When I dive and wear a watch, it’s a 200m Seiko or Aqualand. I also wear a Casio Rangeman when cave diving. It takes abuse better.
Professional dive watches w/HE valves…lol.….show for anybody but sat divers.
