Cartier Tank Manual Winding Cal.ETA2512-1
Symptom: Poor accuracy (unable to measure)
Repair contents: Overhaul and case cleaning
Repair cost: Overhaul: 22,000 yen
I disassembled and cleaned it. The movement is ETA2512-1. It is a machine that was often used in Cartier watches from a while ago. It is a ladies' hand-wound watch.
The accuracy is completely lost, and by observing the movement of the balance wheel, you can see whether there is a problem with the hairspring. In the photo, it looks badly deformed, but in reality it is more tangled than deformed.
Corrected. We remove the tangled parts while fixing them so that they do not deform. If the deformation is severe, the precision will not be achieved by fixing them, so replacement may be necessary. Since replacement is not possible for older models, we ask that you look at the precision range more broadly.
I assembled it.
For Cartier quartz watches, parts may not be available or may be expensive, so an estimate may be required. Cartier's solid silver and gold-plated cases will oxidize and become dull, but they can be cleaned up by rubbing them with an eraser.
We will continue to provide repair information.
