    The Plaisted Polar Expedition Speedmaster
    "Apparently, insurance salesman and amateur adventurer Ralph Plaisted and a few friends decided on a lark to see if they could get to the North Pole on snowmobiles, the first land attempt. They had one failed try then succeeded in 1968 after a 43 day effort. They (Plaisted and 3 friends) used Ski-Doo snowmobiles, 300cc with 16hp, amazing in today's world of 150hp sleds! The used Omega Speedmasters that not surprisingly, performed quite well (44 days at an average -52°C)."

    This sounds impressive until you think about it. If the conditions on these guy's wrists were "-52°C", they would have returned without hands.

    The same applies for the moon watch. Extreme conditions are implied when in fact the watch was in normal conditions of pressure and temperature. Eliminating or reducing gravity would also eliminate any position error and make the watch run at an even more consistent rate.

    Yes, most times the watches were in close to normal conditions, but on the moon missions they were strapped to the outside of the spacesuits on long NATO bands. Don't know for how long they were exposed, but there is a lot of photographic evidence.


    (now, whether or not it's photographs taken in a studio is another story )

    Assuming 1 ATM of pressure inside the watch and none outside, that's still only a 1 ATM difference in pressure. Most watches will maintain at least a 3 ATM difference before they even call them water resistant.
