Longines, the prestigious Swiss watchmaker, was founded in 1832 by Auguste Agassiz in Saint-Imier. The brand, officially named “Longines” in 1867, quickly established a reputation for precision and quality.
Caliber 12.68z is one of the brand’s most celebrated manual-wind movements, produced from the late 1930s through the 1950s. This caliber was a versatile workhorse known for its exceptional quality, precision, and robust design, typically featuring a small seconds sub-dial. Used in pilot’s, military, and dress watches, vintage Longines models with the 12.68z movement are highly sought after for their technical excellence and association with the brand’s golden age.

This piece features a very rare gold-plated case, as most of the 12.68z come in a steel case. It is a bit worn on some areas – please check the photos. The dial shows a nice, uniform patina. The watch features a new brown leather strap. It will fit wrists of up to 21 cm. Lug width is 19 mm.
Water resistance has not been tested, therefore it must be treated as NON-waterproof.
The watch will be delivered in its original Longines box as seen in the photos, for a better protection during transportation and for a smart and safe storing once you receive it.

As with any other vintage mechanical watch, exact accuracy cannot be guaranteed, as it depends on many factors, including your kind of use. It has been regulated in different positions to minimize the average time gain/loss. The watch has been serviced in November 2025.
