Object description

Dial Configuration and Cataloguing Discrepancy

The watch features a circular gold-toned dial detailed with applied rectangular block hour markers and baton hands. Dial inscriptions include applied cursive 'Mido' over 'COMMANDER' at the 9 o'clock position, 'OCEAN STAR datoday' at 6 o'clock, and cursive 'Chronometer' at the 3 o'clock position.

A cataloguing discrepancy exists regarding the calendar display. While the auction listing states the watch has a 'day date window at 3', photographic observation shows a framed, vertical aperture displaying the day ('SAT') and date ('4') positioned at 12 o'clock.

Evidence for this section
  • “circular gold dial with block hour markers and thick hands, day date window at 3”
  • “Framed vertical aperture displaying the day ('SAT') and date ('4') situated at the 12 o'clock position.”
  • “Dial inscriptions include applied cursive 'Mido' over 'COMMANDER' at 9 o'clock, 'OCEAN STAR datoday' at 6 o'clock, and cursive 'Chronometer' at 3 o'clock.”

Case and Bracelet Construction

The timepiece features what the auction description documents as a '36mm gold plated case'. Visible observation notes a round gold-plated case fitted with a multi-row articulated metal bracelet displaying light surface wear.

The bracelet is catalogued by the auctioneer as an 'original mido bracelet'. Case back stampings and specific bracelet clasp markings are not visible or recorded in this source.

Evidence for this section
  • “36mm gold plated case”
  • “on original mido bracelet”
  • “Round gold-plated case fitted with a multi-row articulated metal bracelet showing visible light wear.”

Reported Movement and Operating Status

The cataloguing states that the case houses an 'automatic chronometer movement inside'. Movement caliber, jewel count, and internal mechanical condition are not detailed or visible in the listing data.

Regarding operational status, the seller reported that the 'watch is currently running'. Specific timekeeping accuracy, amplitude, and service history are not recorded in this source.

Evidence for this section
  • “automatic chronometer movement inside”
  • “watch is currently running”

Open research questions

  • What specific automatic movement caliber is housed inside the case?
  • What reference and serial numbers are stamped on the case back or interior?
  • What markings or references are present on the Mido bracelet clasp?
