Catalogue description

Dealer description — S.Song Watches

If there was ever a sleeper of a watch, this could very possibly be it. Thought to be fake initially due to certain discrepancies, these Lemania ‘Dive Supervisors’ issued to the Royal Navy were proven by the community at the Military Watch Forum to be genuine and in fact one of the rarest military issued watches ever made. The proof that this watch was genuinely issued to the Royal Navy is provided through two corroborating documents. The first is from a Def Stan (UK Defence Standardisation) document (64 Table III.a) that states ‘0552/160647’ as a ‘supervisor’s watch. These markings are found on the back of this Lemania. The second is from a Royal Navy dive book (BR 2806 Chapter 3334.1) that states ‘two types of watches are provided for use when diving- the diver’s watch ‘Rolex’ or ‘Omega’, and the supervisor’s watch, ‘Lemania’. As we all know, the first watches mentioned are the Rolex Mil Sub and the Omega Military Seamaster 300. As for the third it is agreed to be the very Lemania you see. Dive Supervisors were not required to dive, but instead were always top-side supervising. This is further supporting evidence as the Lemania Dive Supervisor is not similarly robust as the Rolex or Omega. That being said, it is still housed in a Ervin Piquerez S.A. (EPSA) super compressor case. These cases were used by many companies who also produced dive watches such as Enicar and Jaeger-LeCoultre. Despite seemingly small at 34mm, this watch wears much larger due to it’s unusually long lugs. The no-date Lemania Dive Supervisor was issued for one year only in 1965, with a date version issued in 1968. An extremely rare watch, it is estimated only 300 or so were issued. As the Military Omega Seamaster 300, Rolex Mil Sub and Lemania Diver Supervisor are all historically tied, for those who know, owning the trilogy is somewhat of an achievement.

Historical context

Modern Mechanical Horology (1945 – 1969)

Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.

The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide

Dive and water-resistant watches

Keeping water and dust out of a wristwatch was a long-standing challenge. Rolex's screw-down Oyster case (1926) and Omega's Marine (1932) were landmarks; in the early 1950s Blancpain's Fifty Fathoms and Rolex's Submariner defined the professional dive watch with rotating bezels for timing dives, luminous dials and high water resistance. The ISO 6425 standard (1982) later codified what a 'diver's watch' must do.

Dive watches became icons of post-war design and exploration, and their evolution — helium escape valves, ceramic bezels, saturation-diving depth ratings — records the history of underwater work.

What to look for

  • Unidirectional or bidirectional rotating bezel with minute markings.
  • Screw-down crown and case back; depth rating printed on the dial.
  • Luminous hands and markers (radium before c. 1960, tritium c. 1960–1998, then Super-LumiNova).
  • Reference numbers on the case between the lugs or inside the back.

Dating clues

  • Screw-down Oyster cases: from 1926.
  • Professional dive watches: from 1953.
  • Tritium 'T' marks on dials: c. 1960–1998.
