CALIBERS

Legacy Chronographs are powered by pristine and authentic new original stock (NOS) Valjoux 23 & 72 calibers, carefully treasured for almost 70 years, superbly terminated by hand to the highest degree, down to the smallest detail, by a single master Swiss watchmaker of Ultimor

From its renaissance, Ultimor is developing a proprietary chronograph caliber, authentic heir to the legendary Valjoux 72 movement

Visually and architecturally affiliated to the Valjoux 72 chronograph, Ultimor new caliber will take advantage of every technological progress accumulated over the past 70 years, both in terms of performances and functions

Manufactured entirely in Switzerland and certified according to the highest watchmaking standards, this caliber is expected to be released by the end of 2025
