What came in
Heavy desk wear across the lugs and bracelet, chronograph running but sluggish, no service history.
The lug edges had been softened by an earlier polish elsewhere. We rebuilt them with laser welding before refinishing, so the case keeps its original proportions instead of losing more metal.
Work carried out
