Design
- Case and Bezel
- The timepiece is housed in a tonneau-shaped stainless steel case measuring 42 mm in diameter. It features a diver-oriented construction, utilizing a screwed case-back to achieve its water resistance rating of 2000 meters. The right side of the case incorporates guards that protect the winding crown from accidental impacts. A unidirectional revolving bezel is mounted to the top of the case, featuring a 60-minute graduated scale for the measurement of decompression times. The design maintains an integrated aesthetic, transitioning into a black rubber strap that is secured by a Bulgari-branded stainless steel deployant clasp.

- Dial and Complications
- The watch is configured with a black dial featuring central hour, minute, and seconds indicators. Numerical indices are present at the 12 and 6 o'clock positions, with additional markers distributed around the chapter ring. Luminous material is applied to the hands and hour markers to facilitate reading in low-light conditions. A single horological complication is integrated into the dial layout: a date display positioned at the 3 o'clock aperture. The dial is printed with technical specifications, identifying the watch as a chronometer and denoting its depth rating.
- Condition and Identification
- The auction description assigns a high grade to the object, specifically noting the case as "as new" (Grade 1). The dial and movement are also attributed the highest condition ratings provided in the grading system, suggesting minimal wear to the primary components. The watch is identified by the model name "Diagono Professional" and the reference number SD 42 S. The individual case number D 0093 is engraved upon the piece. Signatures are reported by the seller on the dial, case, and internal movement.
