Disassemble, clean and then reassemble
The 15 series is said to be a masterpiece, but there are considerable individual differences. This particular watch has little wear and is in good condition. The 15 series (and not just any automatic watch) has a strong torque, so if you use it while it runs out of oil, the parts will wear out. By the way, the shock spring is a flower kif, giving it a retro feel.
Back side (dial side)
Assemble the back side as well. The date advance mechanism does not have a datejust, so the date advances slowly.
Attach the dial and hands
The silver dial and withered leaf hands create a nice look.
Casing
After casing, the automatic winding mechanism is attached. Now we will carry out a running test.
Judging from the serial number, it appears to have been manufactured around 1962. The bracelet is a full-link rivet bracelet, and it is in good condition considering its age. We will post it on our online shop once it arrives.
