This is a beautiful example of the first electronic chronograph chronometer ever made and at the time Longines flagship chronograph, sharing the identical movement to the Omega Speedsonic. I wouldnt think it needs much introduction to Longines enthusiast but they are a rare bird and far less common than their Omega Speedmaster'Speedsonic' brother. The watch was introduced in the early 1970's as Longines flagship chronograph, considerably more expensive than the comparative chronographs and the only one that was Chronometer certified. The Longines was an adaptation of Omegas mosaba movement or as we know it the F300, a mechanical movement which ran on a battery and was controlled by tuning forks which vibrated at a frequency of 300Hz. The movement was made under licence by Bulova, the chronograph version then adapted with basically and extra'layer' for the chronograph operation. The movement in this watch was known as the Mosaba meaning'montre sans balancier' translates for'watch with no balance'. So good was the quality of these movements that in 1978 Omega send approximately 12 of this model were sent to NASA with Radial Dials (and Star made cases) to test them as a possible replacement for the famous 145.022 moon watch, they passed all of the rigorous NASA tests. They were produced in small numbers (due to cost of the movements) and when new was one of the most expensive Longines chronographs in the range in its day it was amongst the most advanced Longines made, even by todays standards it is a work of genius and becoming increasingly hard to find in good condition.

This example is in excellent condition. The watch is fully functioning and working. Case size: 35 x 40 mm.
