Hi,
Just wondering, In the owners manual, it says to get seamasters checked every year for watertightness. I dont know if any watch repair can do this, and dont know if it is truly necessary, but, regardless, I would like to know what is an approximate lifetime of the seals in the seamaster, and how long can one assume the watch will remain watertight? from an engineering type perspective, what is the mechanism of the watertightness? I hear that it is due to the threading of the crown, back, etc, and if that is the case, then rubber gasket seals shouldnt matter, and as long as it is fully tightened, all is well.
I wonder about this because up until last year, i still wore my fathers automatic timex, which he bought in the early 70s! I wore it swimming in our pool, and it was fine. Never got a new gasket, just had a pop on back with a rubber washer, and I would even open it up from time to time. With the obviously much better screw design, and overall application design of the seamaster, I am curious if it will have a watertight lifetime like my father's timex. i am not going to wear it diving 1000ft, ill maybe wear it in the pool on occasion, but usually take my watch off even then. I am just curious, because I am still impressed that the automatic movement timex watch from the early 70s ran continuously, and stayed watertight for so long. The mainspring wore out before the rubber gasket messed up.
thanks for your time
