There was a lot going on in the watch world in the 1960’s. There was the race to make the first automatic chronograph, the commercial introduction of the electric watch and the high-beat cold war. An easy way to think about the beat rate of a watch is to think about how many times that watch ticks or beats in a single second. The more beats in a single second the higher the beat rate with anything around 10 beats per second (36,000 bhp) being generally considered high-beat. The basic thinking is that the more beats in a second a watch can measure the more accurate the watch, and marketing teams at big watch companies love accuracy as it is generally associated with quality.
There were three main brands involved in the high-beat battle. Girard-Perregaux kicked things off with the introduction of their Gyromatic and they were quickly followed by Seiko who introduced their Lord Marvel watch. Last to enter the game was Longines with their Ultra-Chron. The example seen here is cool for two reasons. The first is that it has its complete inner and outer box accompanied with its chronometer certificate and ultra-chron cleaning cloths. The second is its tigers eye dial.
Longines debuted their Ultra-Chron line of watches in 1967. When they showed off the watches they were accompanied by the tag line “the world’s most accurate watch” and they backed up this claim by guaranteeing them to within +/- one minute over the course of a month (approximately two seconds per day). Longines had great success with the Ultra-Chron movement and put it into a number of different watches during its production run from 1967 to the mid 1970’s. You can find dress watches, square watches and cushion shaped sport watches. Ultimately, the popularity and accuracy of the quartz watch put an end to the Ultra-Chron, but we still love them for their special place in watch history.
The Case and Bracelet
The 10k yellow gold filled cushion shaped case is in very good condition. It retains the correct brushed and polished finishes and outside of scratches from normal wear and tear is free of any major defects. The original Kestenmade bracelet is in matching condition and will fit up to a 7.5-inch wrist.
The Dial and Hands
The tiger’s eye dial is in great condition with no major flaws to note. The design is minimal with applied gold hour markers and simple gold hands. There is no luminous material and there is a date window between 4 and 5 oclock.
This watch features an automatic Longines calibre 431 movement. The watch is running and the service history is unknown.
