This Omega military wristwatch, reference 2777-1 and NATO number 6B/542, was manufactured in 1953 to British Ministry of Defence (MOD) specifications. The watch features a black dial with white Arabic numerals, skeletonized hour and minute hands filled with luminescent material, and a white seconds hand.

It is characterized by its "Thin Arrow" dial, which distinguishes it from the later "Fat Arrow" variants that were modified in the 1960s with tritium-replaced dials. , retaining the radium-based luminescent material and the original narrow broad arrow symbol. The case is designed to meet strict military guidelines, including protection from magnetic fields via an inner dust cover.

Condition and Authenticity
The condition of the watch is presented as untouched, with the dial exhibiting significant character due to historical patina. , though some loss of material is documented in the auction description, specifically at the 10 o'clock index. The status of the piece as a surviving "Thin Arrow" variant is attributed to either accidental oversight or a possible early service replacement that occurred prior to the general decree regarding radium removal. Without definitive service records, its history remains partially speculative.
The Thin Arrow Configuration
While many of these watches were returned to the manufacturer in the 1960s for dial replacement—where the radium was substituted for tritium and the broad arrow was repainted in a thicker style known as the "Fat Arrow"—this particular watch retains its original thin arrow. , which shows visible degradation, notably near the 10 o'clock marker. The presence of the thin arrow indicates that this specific piece did not undergo the mandated conversion process that altered the majority of the Omega military contract supply from that period.
Design and Military Specifications
The Omega 2777-1 was produced to meet stringent guidelines issued by the British Ministry of Defence in 1953. These specifications were comprehensive, covering the internal movement architecture and external visual elements to ensure the watch was suitable for military field use. Central to the design is the case, which was engineered to avoid highly polished surfaces and required specific magnetic protection via an integrated inner dust cover. The dial, conforming to standard military requirements, presents a black background with legible white Arabic numerals and skeletonized hands to accommodate luminescent infill for visibility in low-light conditions.

Research required

  • Research required: The exact reason this specific example escaped the 1960s dial replacement program remains unknown
  • Research required: The possibility that the current dial is an early service replacement cannot be entirely excluded
