Franck Muller: Cal. ETA1727-1

Symptoms: Scheduled maintenance

Repair contents: Overhaul, packing replacement, case cleaning

Repair cost: 22,000 yen

This is an overhaul of a Franck Muller Long Island. It is a hand-wound small second watch with a very simple structure.

For this reason, we sometimes recommend repairs at an authorized store.

I disassembled it and cleaned it.
