    MTM Seals new depth rating

    i was just looking on the MTM wesite and i just noticed that the people over there have changed their depth ratings on the MTM seal range of watches, if i remember correctley it used to be 12,000 metres but its changed to 1000 metres.
    http://www.specialopswatch.com/cart/....cgi?detail=33

    At watch report it says clearley that its 12,000 metres: "Waterproof (not water-resistant) to 12,000 meters, 39,370 feet, 6,600 fathoms, 7.5 miles, or 2.5 leagues"

    if anyone has any idea of why theve chaned this it would be a great help.

    Is that a hex-head cap screw for the crown?

    Don't know, but looking at the pic, it is a filled watch and it clearly states 12000m on the dial.

    There are only two kinds of people in the world, the ones that own Sinn U1, U1W, U2, UX, U212 and U-Unlimited, and ones that donít.

    I am the ruler of the attunement to my inner self.

    Maybe the case isn't filled with silicon oil anymore. I believe that's how they achieved the 12,000 meter depth rating.

    The extreme pressure will crush the quartz crystal making the watch not work after 5,000 meters. (I think, it's something like that.) Sinn did the same thing to one of their watches.

    Yes, some of them were oil filled. I have not looked on the site, but Im guessing the 1000m are not.

    Ok after a few searches I found the answer. It is because the vacuum-tube around the quartz crystal implodes between 4,000 and 6,000 meters in a oil filled watch. A "dry" watch with a extremely tough case can go deeper. I think this is why MTM lowered the WR rating. I believe the Sinn UX was rated from 12000m to 5000m once this info was discovered.

    12000 meters, 5000 meters, 1000 meters really makes no difference, because its owner will be long cold and dead before reaching any of this depths....

    The big difference between an analog and a digital watch:

    - An analog watch is an interpreter (about 10-11 minutes to eleven)
    - A digital watch leaves no room for interpretation but only facts (10:58:50)

    This is a perfect example showing us that the dive watch manufacturers are not really testing their watches. It's all the rage to pump out a big beefy case and then to put these big WR numbers on the dial, but when it comes right down to it, no one is testing these things to see if they really can do what the manufacturers are claiming that they can.

    It's no wonder that many of these companies are secretive of their testing programs.
