Partially verified

This 1995 Rolex Day-Date wristwatch, model reference 18378, features an 18K yellow gold case and a matching 8385 President bracelet.

Complementing the dial, the bezel is factory-set with diamonds and ruby markers positioned at the 12, 3, 6, and 9 o'clock positions. The watch is powered by the Rolex caliber 3155 movement, introduced in 1988, which provides a double-quickset complication for the day and date functions.

This watch includes no additional accessories, although it is reported to be in functional timekeeping condition.

Object description

Case and Bracelet

The 18K yellow gold case exhibits signs of previous use and remains in well-preserved condition. The lugs are described as thick and symmetrical with minimal evidence of polishing. The 18K yellow gold bezel contains factory-set diamonds interspersed with ruby cardinals at the primary hour markers. The case back retains its original finishing.

The watch is fitted with an 18K yellow gold 8385 President bracelet, which contains 23 links. While this bracelet was sourced with the watch, the auction description notes that it dates to an earlier period than the head. The bracelet demonstrates minimal stretch and is sized to accommodate wrists up to 7.25 inches.

Evidence for this section
  • “The strong 18K yellow gold case is in well-preserved condition”
  • “18K yellow gold bezel with factory-set diamonds and ruby cardinals”
  • “The 18K yellow gold Rolex 8385 President bracelet was sourced with the watch but dates slightly earlier”

Dial and Hands

The dial is a satin-finished yellow version, referred to by the vendor as a "lemon" dial. It is characterized by a central motif of factory-set diamonds and ruby hour markers. The dial condition is described as virtually flawless, showing no age or wear.

The original hands feature a tritium inlay that has developed a cream patina. Inspections under UV light reported by the seller show no degradation of the tritium material. The layout follows the standard Day-Date configuration, with the day aperture at the 12 o'clock position and the date cyclops at the 3 o'clock position.

Evidence for this section
  • “The original and rare satin yellow or "lemon" dial features factory-set ruby markers with a center diamond string motif.”
  • “The original hands are in perfect condition with the tritium inlay featuring a lovely cream patina”

Movement and Functionality

The watch utilizes the Rolex caliber 3155 movement. Introduced in 1988, this caliber is designed with a double-quickset complication. This mechanism allows for the independent adjustment of the day and date via the crown.

When the crown is in the second position, rotating it clockwise adjusts the date, while counterclockwise rotation adjusts the day. The seller reports that the watch is keeping time appropriately.

Evidence for this section
  • “Rolex introduced the cal. 3155 in 1988, this movement featured an updated double-quickset complication”
  • “While in position two of the crown, rotating the crown clockwise will promptly change the date, while counterclockwise will quickly change the day.”

Open research questions

  • What is the full, unredacted serial number for this movement/case?
  • Can the specific production date of the bracelet be confirmed to verify the disparity between the head and the strap?
