Vacheron Constantin 85180 40 mm: what to check on a used piece

Vacheron Constantin 85180 40 mm is the reference in this note. Put the watch on the wrist before you judge the photographs. The catalog width is not the feeling. Lug to lug, the place the clasp lands, and whether the end links bite the case are the fit questions. Slide a finger under the center of the case. A gap there can be normal on a curved lug, and a gap at one end only means the bracelet is twisted. Take the watch off and look at the case back edge for a ring of wear from a desk. That ring tells you the piece was worn, which is what a used watch is. It does not tell you the reference. The reference is still the engraving. Compare the dial color with the bezel insert in daylight, not under a shop lamp. Paint that has faded on the dial but not on the insert, or the reverse, means one of those parts was replaced. Write down which surface looks newer. People change inserts, crystals, and straps more often than they change cases.
