Lemania HS9 Monopusher £4250

A rare Lemania HS9 Broad Arrow Series I Royal Navy Monopusher Chronograph Military Watch.

This Monopusher watch is an early Lemania with the scalloped rather than notched case-back. The HS/|\9 on the case-back indicates Hydrographic Service, the Broad Arrow symbol for military use, and the 9 indicating it is a chronograph. A serial number of “4562”, means this Lemania comes from about 1948.

The condition of both the dial and movement is superb. At 38.5mm, it’s well suited to modern tastes.

The Lemania signature on the dial, (earlier where examples were unsigned), the Circle T printed on the dial; the dial will have been replaced with a Tritium one; either during normal servicing or it was re-issued under its NATO stock number. The face retains its original “replacement dial” Tritium lume and markings.

The gilded 15CHT movement is fitted with a self-compensating Breguet hairspring, column-wheel chronograph mechanism and 17 jewels and was serviced recently.

The Monopusher (the single button at 2 o’clock), operates the chronograph. There is an elapsed minute counter at 3 o’clock, which allows for timing up to 30 minutes.

The steel case is in very good condition – a few marks from wear but overall very smart.

Lemania supplied luxury brands such as Vacheron Constantin, Patek Philippe and Omega. The Cal. 321 in the Speedmaster Moonwatch was an adapted Lemania!

Sadly, Lemania no longer exists – it is now a cult brand, revered by collectors. Good original examples of these watches are rare. This Lemania “Series I” Monopusher represents an excellent opportunity to acquire a fantastic piece.
