Longines Ultra-Chron box Edition automatic steel and leather watch L2.836.4.52.8

Inspired by the original Longines Ultra-Chron Diver from 1968, the new model and its new high-frequency calibers represent the first reinterpretation of what Longines is known for: its status as a pioneer in the world of sports timing.

It will please both fans of vintage watches and lovers of high technology. The accuracy of the Longines Ultra-Chron is confirmed by its certification as an "ultra-chronometer" by TIMELAB, an independent testing laboratory in Geneva. This designation goes beyond the usual "chronometer" certification. This model, with a leather strap, is delivered in a special presentation box containing a black NATO strap made from recycled material.
