LEMANIA H.S.9 - Royal Navy Fleet Air Arm Pilot's Chronograph 

Stainless steel Lemania pilot's chronograph wrist watch specially produced for the  the Royal Fleet Arm (Navy Airforce) and normally only issued to their navigators.

Heavy stainless steel case with screw-on back. Fixed strap bars. Chronograph button mounted on side of case at 2 o'clock position (starts, stops and resets chronograph function).

This watch shows
a short service life, as most of these would have ended up being double struck, but this retains its sole HS9 number.

Original  dial with black numerals, wonderful patina due to its age. No T-dial, means,that this watch escaped the wholesale redialing of these timepieces which took place around the early to mid 1960s when all radium dials were replaced or reprinted to have the less radioactive 'tritium' luminous compound.

Chronograph minute register (30 mins.) and subsidiary seconds register. Outer chronograph seconds chapter divided into 1/5th seconds. Luminous hands and hour markers (luminous paint faded with age.)

Case width (not including crown or chrono. button) : 38.5mm.
