Valjoux 92 Hugex Chronograph Service

Vintage chronographs are my favourite , i recently aquired this watch to add to my collection. On receiving this watch i could tell that the mainspring was broken so hopefully a service should do the trick. The case will need replating at some point but for the mean time its wearable 🙂

Disassembly pictures below.

The mainspring was snapped and was replaced

Once the parts were cleaned in the machine (excluding the chronograph parts, they were manually cleaned) the movement was reassembled.

The base movement is timed and calibrated.

The reassembly continues.

The movement was cased up
