Object description

Case and Dial

The watch is housed in a 36 mm stainless steel case complemented by a machined steel reeded bezel. The dial features a grey soleil finish, providing a distinct appearance compared to more common colorways. Hour markers are rendered as simple stick indices, and all dial text, including the brand name and the “Oyster Prince Date-Day” designation, is printed in white.

The dial includes a signature shield logo situated at the 12 o'clock position, directly above the day display window. The date aperture is located at the 3 o'clock position and is magnified by a cyclops lens integrated into the crystal.

Movement and Functionality

The watch functions as a self-winding timepiece with both day and date complications. The day is displayed in full through a wide aperture at the top of the dial, while the date is shown in a window at 3 o'clock. The vendor notes that the watch utilizes third-party ETA movements, which were incorporated into this model line to maintain accessibility.

As reported by the vendor, the watch has undergone a full service by their watchmaker to ensure operational readiness. The day and date displays are noted to be set to the English language.

  • “The watch has been fully serviced by our watchmaker and is ready for its next adventures.”

The watch itself is identified by the reference 94510 and carries the serial number 102xxx, which the source dates to 1984. This reference represents a shift toward the Rolex-style aesthetic within the Tudor catalog of the era.

Open research questions

  • What is the specific movement caliber installed in this reference 94510?
  • Does the clasp date of 1970 suggest the bracelet is a later addition to the 1984 watch case?
