This is a Royal Navy Fleet Air Arm one button chronograph from the late 1950s.
Unlike the later “asymmetric” one button chronographs, this is a much larger version and unlike the later one this case was used by Lemania alone.
Fleet Air Arm navigator’s wrist chronograph with the case engraved with the stock control number 0552/924-3305.
The dial is silver with large black Arabic numerals for the except 3 and 9, the subsidiary dials are quite small in comparison to the rest of the watch. There is a circled T below the centre post, indicating that the watch uses tritium on the hands although there is no luminous on the dial, and it is obvious that there never was.
The movement is a Lemania caliber 13CH-1 with 17 jewels, gilt finish, column wheel operation of the chronograph functions and no shock protection on the balance. The movement is not numbered.
The movement is 95%, whilst the dial and the case are both 85%.
The watch measures 39mm Diam, 46mm lug to lug, it is 14mm high and takes a 20mm strap and a new NATO (G10) strap is fitted.
