Watch Overview

This Longines pocket watch from 1921 is a well-preserved example of early 20th-century craftsmanship. Made in Switzerland and housed in a 10K yellow gold-filled open-face case, it features fine engraving and a classic vintage presentation.

The watch is powered by the Longines caliber 18.79, a 15-jewel manual-winding movement with small seconds, three adjustments, and movement number 3968247. The mechanism has been fully inspected and confirmed to run accurately.

The white dial shows attractive age and patina, with gold-tone Arabic numerals, a minute track, matching hands, and a sub-seconds register at 6 o’clock. The layout maintains a clean and readable appearance consistent with Longines design of the era.

It is cased in a 43.7mm round case and comes with a 34 cm chain and in a Longines presentation display box, adding completeness to the set. Overall, the watch remains in good vintage condition with wear consistent with age. Fully authenticated and ready to enjoy or add to a collection.
