New to watches, I would venture a guess. Since it was behaving as expected for a full 8 days, then started to switch the date incorrectly, would imply something broke, or became misaligned, or loose at day 8.
Obviously I haven’t a clue, but it’s fun to speculate!
would appreciate and update when you figure it out.
A gold plated champagne dialed "Kudu" joins the club.
This 17 jewel Swiss front loader needed a service, a crown and stem to get it running.
It also benefited from a complete valet, and a crystal polishing session.
Finding and fitting a suitable stem was the most tricky part, since the original had broken off right at the edge of the base plate, so extracting without stripping it down was a non starter, and finding something to match the broken stub in my "pile of random stems" took a fair bit of scratching around and experimenting.
It looks a whole lot nicer in real life than it does in my rather badly lit photograph.
The strap was borrowed from an HMT Kohinoor which is hopefully going to be the next patient up on the healing bench.
Nice to be a part of the group. I lurked around awhile go. Just finished level 2 of Mark’s course.
I’ve been a member of the NAWCC for many years, and taken their onsite pocket watch repair course, and repaired many since. I also restore old clocks, both the case and movement. Picture attached is of a recent restore. This clock is an 1894 Ansonia that was ready for the trash pile.
I am also in the midst of building a skeleton clock from brass stock. I use a Sherline lathe and mill to turn the wheels and cut the teeth. It has been many years in the making, but has taken its first ticks this year.
looking forward to more learning and more work on watches. Mark has a great and easy style for learning. I’m almost finished servicing my first automatic watch I ever bought, a Tissot embedded with an ETA 2824-2. The mainspring just arrived.
