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,...

IWC Tonneau Old Inter: Cal.423

Symptoms: Immobility (spring broken)

Repair contents: Overhaul, case cleaning, spring replacement

Repair cost: Overhaul: 27,500 yen + parts: 5,500 yen Total: 33,000 yen

I took it apart and cleaned it. Old Inter's hand-wound model is famous for being 89, but this one is 423. I think it will be a little thinner.

Old Inter springs have a special shape and use a spring with a horn. Old Inter springs are still available at domestic material stores, but they are...

Rolex Datejust: Reference 79174 Caliber 2235

Symptoms: Regular maintenance

Repair contents: Overhaul, spring and gasket replacement, case and bracelet cleaning

Repair cost: 27,500 yen

I disassembled it and cleaned it. There are no problems due to regular maintenance.

Replace the mainspring and assemble. Since the movements for ladies are small, the work is more detailed, but Rolex's Cal. 2235 has a solid structure and is easy to assemble. There are some models with difficulties with calibers earlier than 2235. I hope to introduce them...

Rolex Datejust: Reference 1603 Caliber 1560

Symptoms: Poor accuracy (unmeasurable) / Deformed hairspring

Repair contents: Overhaul, spring and gasket replacement, case and bracelet cleaning

Repair cost: 27,500 yen

I took it apart and cleaned it. It was made in the 60's and shows signs of heavy use. The balance spring is badly deformed and no longer works as expected.

The hole for the second wheel (the gear with the minute hand) has become deformed and widened. It is adjusted by hitting it with...

IWC Round Old Inter: Cal.852

Symptoms: Poor accuracy and automatic winding failure

Repair contents: Overhaul, case cleaning, automatic winding part replacement

Repair cost: Overhaul: 27,500 yen + parts: 16,500 yen Total: 44,000 yen

We disassemble, clean and reassemble the watch. I think the most common type of Old Inter is the Cal. 8541, but we also receive requests for the 852 and 853. Although the structure of each movement appears to be the same, some parts may not be compatible.

Assemble the automatic winding...
