Longines Admiral HF (New Old Stock)

One of the biggest pioneers in producing high precision timekeepers was Longines.
The history of experimentation with high frequency escapements at Longines starts in 1914, in stopwatches. These had 36,000 vph movements, and they were used, among other things, as timers in the Olympic games
In wristwatches, one of the best-known chronometer-grade watches was the famous High-Frequency(HF), which debuted in 1967 to celebrate the company's 100th anniversary. Those watches used 36,000 vph movements and came out at a time when the competition for accuracy in wristwatches was really fierce.

This one is a classic HF 70s men's watch with large steel case, it has a special water-resistance system, consisting of a one-piece case body detachable from the carrure
The superbly preserved original argentee dial with applied hour markers and baton spheres, with tritium treatment is contained in a large 39mm oversize steel case.

The racing look is also given by the fitted "corfam" style strap. The watch is in New Old Stock condition, with no defects whatsoever and complete with box
