: Hmmm..... May I ask what you mean by
: "thin"??? Is this the thickness of
: the movement, and could you give me some
: examples of the 'thinness' of the 2500 and
: speedmaster lemania 1873???
: Thank you again.
OK, here we go:
cal 2500:
height: 3.9mm
diameter 25.6mm for 35mm watches and 28.6mm for 38 mm 42mm watches
cal lemania 1873
height: 6.87mm
diameter: 27mm
I can even give you the characteristsic of for example two older inhouse movements
cal 1010
height: 4.25mm
diameter: 27.9mm
cal 55x/56x/75x
height: 4.5mm/5.55mm/5.68mm
diameter:27.9mm
Just by looking these two characteristic it is enough too judge about how thin is the eta based calibre. Of course there are thinner movements, but that is not the point here, the 2892-2 was never really tested in very harsh repeated conditions, I have never heard of that. Plus its ball mounted rotor isn't the best winding system as compared to what Omega used before, the jeweled pivot rotor. Someone posted awhile ago a report of an aquaterra used in the sahara, it told more of the resistance of the whole watch than of the movement unlike playing golf or tennis with the watch or other activities/sports including quick and sometimes violent movements.
