The Longines Ultra Chron is one of the most collectable models from its 1960s era. A dive watch with a high beat movement was something of a rarity back then and this new Box edition offers that old school style with modern tech. Not a diver though, more of an adventure sport all-rounder.

Here’s the word on this 36,000bph watch;

Inspired by the original Longines Ultra-Chron Diver of 1968, the new model and its new high-frequency calibre represent the first reinterpretation of what sets Longines apart – its status as a pioneer in the world of sports timing.

It will appeal to both vintage watch aficionados 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.

Featuring a steel bracelet, this model is delivered in a special presentation box containing a black NATO strap crafted from recycled material.

The Longines Ultra-Chron’s instantly recognizable 43mm cushion-shaped steel case is fitted with a diving bezel that boasts a sapphire insert with luminescent accents. The eye-catching black grained dial features a white minute track with alternating Super-LumiNova^®-coated batons and rhodium plated appliques.

The original Ultra-Chron logo is proudly applied on the dial and embossed on the caseback. The new Longines Ultra-Chron has a distinctive red minute hand which, like the hour hand, is coated with Super-LumiNova^® for optimal legibility.

At the heart of the new Longines Ultra-Chron is the calibre L836.6, a high-frequency “in house” movement. A watch is referred to as “high-frequency” when it is fitted with a movement whose balance-spring oscillates at 36,000 beats per hour (10 beats every second). These movements, which Longines pioneered in 1914 (to time 1/10th of a second) and 1916 (to time 1/100th of a second), improved precise timekeeping.

From 1959 onwards, Longines made use of the high-beat-movements to increase the accuracy of its watches. Thanks to a reduction of the disruptive effects of shocks or of changes in the position of the movement, the high-beat movement proves to be more stable.
