What I really like is the ETA 2551 movement with 25 jewels. Most ladies watch movement are complete and utter pants, as it is of course hard to fit anything decent into these small cases. This ETA is the exception to the rule. It’s built pretty much in the same way as the larger ETA movements, it’s automatic, has a date, and is tiny!
And with a new crystal, the watch looks great!
When testing, I have problems with the power reserve. After 12 hours, the watch stops. A quick look reveals that the mainspring starts slipping in the barrel way too soon. I open the barrel again, clean everything, and slightly roughen the barrel wall with fine paper. With new braking grease, the mainspring goes back in, and all is well.
