    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.

    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.

    Not really, I could afford it being a student at the University :-)
