This is a Royal Navy issued single-button Lemania chronograph, these watches were first ordered by the Navy for pilots and navigators in the late 1940s and Lemania continued supplying them until the mid-1960s. The watch evolved over the years, and this watch is part of the second style (later versions had an asymmetric style case with more protection around the winding crown and the button).
The dial is original and in very clean condition, the dial has an encircled T, denoting tritium luminous compound for the dial and hands (as opposed to the earlier use of radium).
The single button operates the chronograph (stop-watch function) - the button in turn starts, stops and resets the chronograph. There is an elapsed minute counter, which allows for timing intervals up to 30 minutes.
The condition of both the dial and movement is great - there is some patina on the dial commensurate with age, but the movement is clean and is running very well. The case is all stainless steel and is in very good order - a few marks from wear but overall very tidy. As with all our vintage watches the case has been ultrasonically cleaned, but not polished.
The caseback has had the original military markings removed, this happened quite often when the military provenance was felt to reduce the desirability of the watch (or just possibly to disguise a watch that had been pilfered from the military stores!).
Lemania supplied many different armed forces around the world - their movements are very solidly constructed and keep excellent time, making them a good fit for a rugged life in the services. Lemania are something of a cult brand - no longer in existence today, but much cherished by aficionados. The company specialised in the production of chronographs (that is watches with a stop-watch function built in). Chronographs are inherently complicated things to manufacture and for this reason many watch companies brought-in movements from specialists like Lemania. They supplied amongst others Omega (the movement that powered the first watch on the moon was made by Lemania), and luxury brands Vacheron Constantin and Patek Philippe. Because Lemania often supplied movements to other brands (for which they were uncredited), watches which are signed by Lemania are especially prized.
The watch has been fully serviced and regulated, the chronograph functions perfectly and the time keeping is of the highest order. It is supplied with a NATO fabric strap. This is a great watch for everyday use.
