Rolex Explorer II: Reference 216570: Caliber 3187
Symptoms: Scheduled maintenance
Repair contents: Overhaul, spring and gasket replacement, case and bracelet cleaning, water resistance test
Repair cost: 27,500 yen
Disassemble, clean and reassemble.
I have assembled the time mechanism. The base is slightly larger than the forward 3185. The shock spring has been changed from Kifshock to Paraflex, and the hairspring is blue Parachrom. Other than that, the structure is almost the same.
It has a mechanism that moves only the hour hand, so GMT can be displayed easily.
The dial and hands are attached, the case is put together and a running test is carried out. For sports models, unless the scratches are very severe, we recommend cleaning only and not light polishing.
We will adjust the accuracy while running the watch. Repairs will take approximately 4 weeks.
The repair contents will vary depending on the individual, but we hope that this information will be helpful.
