I'm quite new to celnav, so I never used it for that purpose. It's rate is so small that I do not even bother setting it. > Its supposed to > be some kind of 'water resistant', too. To 100m, it says. I had some insight into that WR-testing. Don't try the 100m in reality. The test is executed in dry conditions, 10atm for 30 seconds. Even a dive into the pool can break the seal and let water in, because it peaks the pressure dynamically. WR 50 means you can take a shower with it on, WR 100 is ok for swimming. Watches for divers are rated at least WR 200m. > I imagine yours was kind of expensive Not really, I could afford it being a student at the University :-) --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
