Rolex Datejust: Reference 1601 Caliber 1560
Symptoms: Regular maintenance
Repair contents: Overhaul, spring and gasket replacement, case and bracelet light polishing
Repair cost: 33,000 yen
I disassembled it. Since it was a watch that had not been used for a long time and had been left as it was, I was asked to do some maintenance before using it. If it has not been used for many years, it is better for the watch to be stored as it is, without forcing it to move. There is no need to wind it every day with a winding machine.
There are considerable individual differences in the 15 series movements. This particular one appears to have been well maintained, and the wear on the first bridge (the spring receiving hole) had been repaired. The repair was done very carefully, neatly following the receiving hole.
Replace the mainspring and assemble.
This is the back side. This particular watch also had a problem with the calendar not being just right, so I adjusted the date feed. Even in the 15 series, there are some models of the 1530 that do not have a datejust mechanism.
The dial and hands are attached. The watch is then placed in a lightly polished case for a running test. The accuracy of the watch changes depending on the condition of the movement, so we will make adjustments as we go.
We hope this information will be helpful to you in determining the repair details and costs.
