Document what came together and what might have been replaced

An antique pocket watch is an assembly of movement, case, dial, hands and crystal. Each part may have different maker marks and replacement history. A dial name is not always a movement maker, particularly on privately labeled or retailer-signed watches.

Start with the movement serial and grade, then measure movement size and inspect setting type. Photograph case markings separately. Inherited watches should be kept dry and not forced open without knowing the case design; a watchmaker can help avoid damaging a hinge or bezel.

Before you buy or compare prices
