Longines 29 mm quartz: what to check on a used piece

Longines 29 mm quartz is the subject of this note. Use daylight if you can. Artificial light hides the difference between a faded insert and a replaced one. Hold the watch at arm length and then at reading distance. The dial should stay legible, and the hands should not disappear into the markers. On a used piece the bracelet stretches, the clasp thins at the fold, and the case back collects arcs from a desk. Those three marks are ordinary. What is not ordinary is a dial that looks new beside a bracelet that is deeply worn, or a bezel insert that is glossy beside a case that is dull. Mismatched wear means a part was swapped. Name the newer part. Then measure. Width across the bezel, lug to lug, and the space between the lugs where the strap sits. Three numbers locate the watch on a wrist better than a nickname does. Keep the nickname in your head if you like. Put the numbers and the engraving in the note.

How it differs

The size written down for this record is 29 mm. Measure across the bezel and from lug to lug before you accept that number. The seconds hand should step once each second. That is the check for a quartz watch. A smooth sweep would mean the movement type on the listing is wrong. 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.

What people change

On the Longines 29 mm quartz, people change the bracelet, the case, or the movement.
