Dial Configuration and Hands
The black dial displays luminous markers, notably an oversized triangular luminescent index positioned at 12 o'clock alongside Arabic numerals at 3, 6, and 9. Time is displayed using sword-style hour and minute hands accompanied by a central seconds hand. The auction catalogue identifies this visual design under the model name 'Seamaster 300 "Big Triangle" Professional Diver' with reference number '165.024 - 64 SC'.
Case and Exterior Construction
The watch features a stainless steel case with a reported diameter of 42mm, alongside catalogued overall dimensions of 47mm x 42mm. The exterior is fitted with a rotating black bezel marked with elapsed minute graduations and a triangular zero marker. The timepiece is fitted with an aftermarket black and gold striped NATO fabric strap, as noted in the auction listing and visual inspection.
Reported Movement and Provenance
The lot description attributes the timepiece to an automatic Calibre 552 movement and states that it is 'In Full Working Order'. However, internal movement components and the interior of the case back are not visible in the provided imagery, meaning the movement calibre, serial number, and functional status cannot be verified from the photograph. The entry lists an approximate dating of 'Circa 1966' and notes provenance from a 'Private London Collector', with a claim that the watch was 'cleared on registered loss database'.
