This is a vintage Doxa by Synchron rectangular wristwatch, dating from around 1968, when Doxa was part of the Swiss Synchron Group. During this period, Doxa produced elegant, reliable mechanical watches under the “Doxa by Synchron” label, combining classic Swiss craftsmanship with simple, timeless designs.

This model features a rectangular case (30x39 mm), a manual-wind Synchron 13 movement with 17 jewels, and a clean, understated blue dial. Its design reflects the minimalist dress-watch style of the late 1960s, with all-original components including the crown and case. This watch is a perfect example of Doxa’s quality during the Synchron era, offering both historical significance and enduring Swiss reliability.
