Lemania Series 2 HS9 Military Single Pusher Chronograph

Partially verified

This Lemania Series 2 HS9 is a military-issue pilot's single-pusher chronograph dating to circa the 1960s according to the source. Encased in stainless steel with fixed lug bars, its screw-down case back is engraved with the British military broad arrow, 'H.S. 9', and serial '4403'. The source reports a white dial bearing Arabic numerals, a circled 'T' indicating tritium luminescence, the broad arrow, and a bi-compax layout recording continuous seconds and elapsed minutes. Operated via a single pusher at 2 o'clock, the manually wound movement is stated by the seller to be Lemania Calibre 15CH with 17 jewels.

Object description

Case Construction and Military Markings

The timepiece features a stainless steel case reported by the vendor to measure 38.2 mm in width, with a lug height of 45.75 mm and a lug width of 20 mm. Direct observation confirms fixed lug bars positioned between the case lugs, as well as a single cylindrical chronograph pusher situated at approximately 2 o'clock adjacent to a fluted winding crown.

The screw-down case back has a brushed finish showing surface scratches consistent with use. It is visibly engraved with 'H.S. ^ 9' above the serial number '4403'. The seller claims this HS9 engraving represents a British Ministry of Defence designation for RAF-issued wristwatches, and lists the crystal as plexiglass.

Evidence for this section
  • “Stainless steel screw case back engraved 'H.S. ^ 9' above '4403'”
  • “Fixed lug bars positioned between the case lugs”
  • “Single cylindrical chronograph pusher situated at approximately 2 o'clock alongside the fluted winding crown”
  • “Lug Height 45.75mm Width 38.2mm Lug width 20mm”
  • “corresponding HS9 engraving on the case back — the British Ministry of Defence designation for RAF-issued wristwatches”

Dial Configuration and Hands

The dial is not shown in the provided photograph, which only depicts the case back. According to the seller's catalog description, the dial is white and configured in a bi-compax chronograph layout featuring sub-dials for running seconds and elapsed minutes, with elapsed time tracked via a central chronograph seconds hand.

The seller also asserts that the dial features syringe hands, luminous hour plots, an original circled 'T' beneath the Lemania signature indicating tritium luminescence, and a broad arrow marking. These features cannot be verified from the visible case back photograph.

Evidence for this section
  • “The clean white dial remains in very attractive condition, showing only minimal blemishes, and retains its original tritium lume , indicated by the circled “T” beneath the Lemania signature.”
  • “The luminous material on the hour plots and syringe hands has aged evenly”
  • “sub-dials recording running seconds and elapsed minutes.”
  • “clearly identified by the broad arrow on the dial and the corresponding HS9 engraving on the case back”

Movement Specifications and Seller Documentation

The internal mechanism is not visible in the provided image. The vendor reports the movement as a manually wound mechanical Lemania Calibre 15CH with 17 jewels and a stated power reserve of 40 hours.

The seller attributes the watch to circa the 1960s and rates its condition as 8/10. The listing states the watch is fitted with a leather bracelet and is offered without its original box or papers.

Evidence for this section
  • “Calibre 15CH Date of Issue c.1960s Jewels 17j”
  • “Winding Manual Bracelet Leather Movement Type Mechanical”
  • “Power Reserve 40 Hours”
  • “Box No Dial White Papers No”
  • “Condition 8/10”

Open research questions

  • What specific caliber stamping and movement serial number appear on the movement plates to verify Lemania Calibre 15CH?
  • Does direct visual inspection of the dial confirm the presence of the broad arrow, circled 'T', syringe hands, and original tritium luminous plots?
  • Does military procurement documentation confirm whether the 'H.S. 9' designation on this reference represents Royal Navy Hydrographic Service stores or Royal Air Force issue?
