Heritage

This watch has been researched directly with Longines Heritage. Using the original case serial number (15,998,890), Longines confirmed that the watch was invoiced on 8 November 1971 to S.A.L.G. (Société Anonyme Longines Genève) in Switzerland.

While Longines cannot officially certify that the watch was subsequently retailed by Türler, they confirmed that this is entirely plausible, as it was delivered through S.A.L.G., the successor to Wirth, making the original Türler double signature fully consistent with the documented history of the watch.

A copy of the correspondence from Longines Heritage can be provided to the buyer.

This is a rare opportunity to acquire a genuine Longines × Türler double-signed timepiece, combining elegant minimalist design, an excellent in-house movement, and the added desirability of one of the most respected historic Swiss retailers. These double-signed examples are considerably scarcer than standard Longines models and remain highly sought after by collectors.
