Rolex Air-King: Reference 14000M: Caliber 3130
Symptoms: Not working/spring broken
Repair contents: Overhaul, spring and gasket replacement, case and bracelet light polishing
Repair cost: 33,000 yen
We will disassemble and clean the watch, replace the spring, and then reassemble it.
I even assembled the time mechanism.
The Cal.31 series has a non-date version (3130) and a date version (3135). The non-date version has a very simple structure.
Attach the dial. The indexes look black in the photo, but they are actually silver.
The case and bracelet will be lightly polished (deep dents and scratches that may cause the case to deform will be left as they are), a waterproofing test will be performed, and after casing, a running test will be performed to adjust the precision, etc. The repair period will be about 4 weeks.
Although it is simple, I will list my repair history. I hope it will be useful for your reference.
