Vacheron Constantin 41 mm automatic: what to check on a used piece

Vacheron Constantin 41 mm automatic is the subject of 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.

How it differs

The size written down for this record is 41 mm. Measure across the bezel and from lug to lug before you accept that number. The seconds hand should sweep. That is the check for an automatic watch. Wind the crown and listen for the rotor only if the case back lets you. People change the crystal, the clasp, and the strap more often than they change the case. Write which part looks newer.

What to check on a used piece

Read whatever engraving is on the case. Measure the width. Watch the seconds hand for a minute. Look at the end links or the strap holes. There is no price in this note, and the note does not grade the watch.

Common mods

Common changes are a new strap, a shortened bracelet, a replaced crystal, and a polished lug. Describe those changes next to the size and the movement type. The case you measured is the watch you have, even when a listing used a different width.
