    Mudman: underwater watch?

    hi guys!
    just recieved my new beautiful mudman! really happy with it!
    anyway, dont understand the "20bar water resist" on the top?
    how far down will it go? in terms of meters, that is.
    thanks

    20bar= ~ 200meters of water column. That is the minimum pressure your mudman (any G) can take. You probably can double or triple that value.

    20BAR = 200M = free diving + snorkeling + swimming + bathing + all non-water activities.

    just don't

    it would be rare anyway for somebody to be diving to 200metres and wearing a standard wristwatch, if you where ever diving to that depth you would have already been through lots and lots of training and have become more aware of what a standard wristwatch can take.
    Basically for a standard wristwatch whatever depth it says on it I'd divide it by 4 and it should be OK(as long as the seals are good).
    By standard I mean one that is not primarily designed for divers, as a diving watch, for diving.

    Theorical ratings vs Reality

    200M = 20M
    150M = 10M
    100M = 5M
    50M = 1M
    30M = 0.3M

    Re: Mudman: underwater watch?

    not a linear performance graph, why would there be such a massive dip in performance for 50metre watches?

    50M watches are OK for swimming, it's not motionless water rating but "live" action, if you want to perform aquatic gestures you should wear a 100M rated watch.

    sorry that's not what I commented on,
    I understand what the figures show but the differentials are so different,

    if you look at the differentials in those figures they go (in ascending order) 30/10, 50/50, 100/20, 150/15, 200/10

    Which for some reason shows a huge drop in performance on a 50m watch.
    The figures may just have been plucked out of the air which is no big deal, but there is a true ratings chart available.

    here you go

    Water Resistant mark - Wikipedia, the free encyclopedia

    Water Resistant 200 m Suitable for professional marine activity and serious surface water sports. NOT suitable for diving.

    A true divers watch though - 200m = Suitable for scuba diving at depths NOT suitable for saturation diving.

    And that's what I meant by:
    By standard I mean one that is not primarily designed for divers, as a diving watch, for diving.

    Re: Mudman: underwater watch?

    We are talking about water-resistant watches, not diver watches as they require ISO certification and individual test.

    The calculation is based on the most common situations where you wear a non-diver watch in real life while the wiki chart gives a theorical estimation.
