Case and Dial Architecture

Visual observation records a cushion-form gold-toned case with a hooded lug arrangement, framing a vertically brushed light dial with rectangular dark-accented block hour indices. Central black hands including a sweeping seconds hand are present, alongside a framed date aperture at 3 o'clock displaying the numeral 8.

The seller's measurements record a 34 mm case diameter (36 mm with crown), a 40.6 mm lug-to-lug distance, and an 11.3 mm case thickness. While the seller describes the dial as an original "gold textured" surface with "gold/black hour markers", the dial appears under studio lighting as pale champagne to light silver.

Reported Movement and Presentation

According to the seller description, the watch is powered by an automatic Timex caliber M32 pin-lever escapement movement operating at 18,000 A/h with a 38-hour power reserve and a date indicator set by alternating between 22 and 24 hours. The vendor details an excenter self-winding system with a rotor arbor operating an excenter and lever, coupled with a planetary differential gear transmitting automatic and manual winding to the barrel arbor.

The internal mechanism is not visible in the provided primary photograph, meaning caliber markings and internal condition cannot be verified visually. The watch is fitted with a stitched brown textured leather strap, described by the retailer as a new-old-stock light brown genuine leather two-piece strap with a 19 mm lug width and 20 mm band width.

Evidence for this section
  • “It is a self-winding watch powered by an original Timex automatic movement pin-lever escapement, caliber M32, sweep second, 38-hour power reserve and 18,000 A/h, date indicator (sets by changing 22-24h).”
  • “The movement caliber M32 – A sophisticated excenter self-winding with just one gear stage. An excenter on the rotor arbor moves a lever, which turns a ratchet wheel via two clicks. A planet differential gear on the dial side transmits the sum of automatic winding (small center wheel) and manual winding (peripheral gear) via the two planet wheels to the barrel arbor.”
  • “Mounted on a stitched brown textured leather strap”
  • “It comes on a new-old-stock light brown Genuine Leather two-piece strap.”

Open research questions

  • Are the dial code digits '46660 3271' printed below the 6 o'clock position on the dial perimeter when examined under magnification?
  • Can physical inspection of the internal movement confirm the presence of caliber M32 stampings and assess mechanical wear on the pin-lever escapement?
