Object description

Case and Dial

The watch features a 38mm stainless steel case paired with an integrated steel bracelet. The case design incorporates a unidirectional rotating bezel with distinct scalloped indentations and engraved numeral markers. The case profile includes protected chronograph pushers and a central crown positioned on the right side.

The black dial utilizes a tri-compax layout for the chronograph registers. It is finished with luminous indices and large Arabic numerals at the 12 and 6 positions. Visible text on the dial identifies the brand, the automatic nature of the movement, its chronometer-certified status, and the water resistance rating of 200 meters.

Evidence for this section
  • “At 38mm, this watch strikes a perfect balance of wrist presence and practicality”
  • “The black dial packs in classic tri-compax chronograph instrumentation”
  • “The steel unidirectional bezel—with its scalloped cuts and engraved numerals”

Movement and Performance

The timepiece is powered by an automatic movement of Swiss origin. The dial explicitly notes that the movement is chronometer-certified, implying a level of precision testing. The watch is constructed as a dive-capable tool, with a specified depth rating of 200 meters, which the source suggests bridges the gap between desk-use and professional underwater application.

The mechanical system drives the integrated chronograph functions alongside standard timekeeping, housed within the steel exterior. The watch is noted to be fully functional despite evidence of past wear.

Evidence for this section
  • “Inside beats a Swiss automatic chronometer-certified movement”
  • “Rated to 200 meters, it walks the line between desk diver and legitimate tool”
  • “just an authentically worn, fully functional slice of late-’90s/early-2000s Bulgari tool-watch history.”

Condition and Provenance

This specific unit is offered without original manufacturer packaging or documentation. The current state is described as authentically worn, with visible patina and wear throughout the steel surfaces. These marks are presented as indicators of the object's history of use rather than as significant damage.

The piece is classified as a utilitarian example of Bulgari's design from the late 1990s to the early 2000s. The source describes the object's condition as functional, emphasizing its history as a tool watch that has been utilized by previous owners.

Evidence for this section
  • “No box or papers—just an authentically worn, fully functional slice of late-’90s/early-2000s Bulgari tool-watch history.”
  • “This Diagono Scuba has lived a life (the patina and wear give it real character)”

Open research questions

  • What is the specific movement caliber utilized within this model?
  • Can the production year be narrowed down beyond the decade-long estimate using the serial number?
