Hi Phasar66.
Mine is keeping excellent time too. It's getting some serious wrist time at the moment.
Haven't had any problems with the date yet, but haven't had it running a full month. I've also read that this is a weak point on these watches. The date wheel is plastic and the teeth get chipped, and from what I've read are now almost un-obtainable. If ours need to be replaced, I believe it will be particularly problematic.........with the stem at 2, the numbers need to be in-between the teeth on the date-wheel.
It can't be that hard to make one could it ? I would've thought some clever person out there would be reproducing them.
As dutchsiberia mentioned above, it's not essential to remove the oscillator module, in order to remove the module. It's just a bit safer to do so. On the plus side, if you leave it in place, the stem cog can't fall out.
I'd be tempted to just live with the date wheel issue you have. If you ever come across a new one, then good-oh, but until then, just enjoy watching that seconds hand sweep around the dial
Rgds.
