Object description

Case and Bezel Construction

The watch features a stainless steel case reported by the seller with a width of 40 mm, a lug height of 45 mm, and an 18 mm lug width. Direct observation reveals an offset crown positioned at approximately 4 o'clock, an acrylic crystal, and an attached multi-link stainless steel bracelet.

A bi-colour rotating bezel encircles the dial, noted by the vendor as a 'coke' bezel. Observation confirms a black insert featuring a contrasting red sector spanning between the 12 and 3 o'clock positions.

Dial and Display

The black dial features a white central crosshair and pale yellow luminous hour markers. Visible dial text includes the brand and model designations 'ACCUTRON' and 'DEEP SEA 666 FEET'.

Reported Movement and Technical Characteristics

The seller describes the watch as being powered by an electronic calibre 2181 tuning fork movement fitted with 13 jewels. Because the movement is not visible in the provided imagery, these internal mechanical specifications remain unverified seller claims.

The date of production is inconsistent across the source text, cited variously as 'c.1969', 'Year 1960s', and 'Date of Issue 1960s (approx)'. Accompanying box and papers are not included according to the vendor.

Evidence for this section
  • “Calibre 2181”
  • “Jewels 13”
  • “Movement Type Tuning Fork”
  • “Winding Electronic”
  • “c.1969”
  • “Year 1960s”
  • “Date of Issue 1960s (approx)”
  • “Box/Papers No/No”

Open research questions

  • Does the case back display a two-character Bulova dating code (such as 'M9' for 1969) to verify the precise year of manufacture?
  • Can direct inspection of the movement confirm the presence and authenticity of the 13-jewel calibre 2181 tuning fork mechanism?
  • Is the fitted stainless steel multi-link bracelet original to the watch or a period/aftermarket replacement?
