Ulysse Nardin Marine Torpilleur Annual Chronograph Blue Limited Edition – 44mm

First produced from 1936 to 1980, the Ulysse Nardin “Chronograph Torpilleur pocket watches” of that time featured the ability to read time down to 1/10^th of a second. Used during the 1936 Berlin Olympics, this precision transformed timekeeping. These chronographs, employed by automobile clubs, geodesic commissions, and scientists on expeditions, they were delivered with official certification that guaranteed their extreme precision.

The 2021 version includes a varnished white or a mat blue dial, and the UN-153 Manufacture movement that has replaced the earlier UN-150 movement. The dial is adorned with silvered, small counters and the annual calendar, which sits at 9 o’clock just above the signature, verifying that Ulysse Nardin has been the leader in “Chronometry since 1846”. The date changes automatically. An invention by Ludwig Oechslin, the annual calendar system employed in the perpetual caliber model of 1996 has been improved, with all settings adjustable both forward and backward by using the crown, making it easy to set time.
