Ref. 760
Excellent condition with box (zipper travel case) and papers.
The Military Chronograph, reference 798, was originally created for the German Armed Forces. During the 1980s, the Tutima Military Chronograph was subjected to the stringent criteria of the German Armed Forces’ central procurement department and critical examination by its pilot’s watch experts. The result in this case was a first-class timepiece with exceptional functionality, optimum legibility, and an innovative design concept, which is still the unrivaled classic watch for the German Air Force.
In 1989, the U.S. Air Force awarded a contract to German watchmaker Tutima to supply watches to its aviators. The model of the watch delivered to American forces was ironically dubbed the NATO, in honor of the European forces that had been wearing it since its introduction in 1984. The watch was initially produced for the German Air Force, but had success with a number of units around Europe. It was a known quantity; it had proven to be a reliable instrument in the cockpit. The U.S. Air Force took a shot on the Tutima NATO Chronograph and a few hundred examples were delivered the following year.
Specification Lemania 5100:
Chronograph movement, self-winding with chronograph mechanism between the dial and base plate. Centrally mounted, unidirectional winding rotor. The inner face of the rotor contains a bent-spring click. A ratchet wheel translates motion to a reduced wheel (the wheel with the drilled holes visible in some photos). The chronograph mechanism is a space and cost efficient navette-type. Despite the relatively high beat rate of 28’800A/h, the calibre has a large Glucydur balance. Nivarox 1 flat hairspring, Triovis regulator, Kif-Flector shock absorber. A large barrel for the Nivaflex mainspring. Large nylon day and dates wheels. The automatic winding mechanism’s reduction gear is also made of nylon. The calibre’s bridges, plates and balance cock are built as a pillar construction. Two nylon half-moons on the periphery of the movement. Movement height 8.2mm, diameter 31mm, weight 21g. Introduced in 1978. The calibre 5100 has been used in many luxury brand military watches such as Omega, Sinn and others. Characteristic traits of the Lemania 5100: the central minute-counter, 24h indicator and 12-hour counter sub-dial.
