Roger sent this Omega to me as it stopped even when worn every day. Before taking apart the watch, I wanted to replicate the problem. After asking Roger for his permission to wear the watch for a couple of days, I fitted one of my leather straps and put it on.
Wearing it for 10 hours every day, it stopped on the third day at 9 a.m., just when I wanted to put it back on. I’m fairly active, and 10 hours of wear per day should easily have done the trick.
This Omega doesn’t have an Omega movement. Even though it’s marked “1108” and “Omega”, it’s really an ETA2892A2. A great movement that beats at 28,800, so nothing wrong with it at all, and nicely decorated on top.
After opening the case back, a dust cover protects the movement. I like those, as you normally can tell the difference, especially as watches get old. The ones with an extra lid tend to stay cleaner.
You can see here that Omega marked the movement as a calibre 1108… might as well have stuck to 2892 as it’s in reality an ETA movement 😉
The bottom plate is nicely decorated with perlage.
I very much like the 2892 – not only is it very accurate, but it has a quick date-set that works very well, it beats at 8 bps, has a hacking second, and it is well constructed.
Having taken the balance and pallet fork out, you can see the gear train with central second. The little brass lever at 7 o’clock is the hacking second lever that stops the balance wheel when the winding stem is fully pulled out.
The barrel bridge with the winding gears.
Waiting for a new mainspring, I put all the cleaned parts into a dust proof container. I’ve already put the balance jewels back and oiled them.
The mainspring has arrived.
The barrel wall gets some braking grease.
I start off with the barrel bridge, and then put in the gear train.
Top plate put together, with the balance happily swinging.
Now it’s time for the bottom plate.
Ready for the dial and hands.
This is why I like the ETA2892!
I put the case back on with a new gasket, and check that the watch is water tight.
A great Omega with a sturdy, water tight case, and a super movement.
