Up for sale is a stunning, neo-vintage Bulgari Diagono Sport Chronograph, reference CH 35 C2SLD (often designated under the broader CH 35 S family). This rare execution stands out beautifully with a pink Mother of Pearl dial accented by factory diamond hour markers. It comes mounted on its original padded black alligator strap with a signed stainless steel pin buckle. According to the included original warranty booklet, this piece was originally purchased on March 12, 2005, at an authorized Bulgari boutique in Bangkok, making it a stellar example from the height of mid-2000s architectural luxury design.

Condition: Bezel: Overall clean with crisp, sharp engraving of the iconic "BVLGARI BVLGARI" text. It displays some minor hairline marks and faint surface scuffs consistent with careful wear, but preserves its original brushed finish lines. Crystal/AR Coating: The sapphire crystal is completely clear and free of any deep scratches or chips. The anti-reflective treatment is intact, letting the shifting pink hues of the MOP dial pop in direct light. Case: The 35mm brushed stainless steel case is structurally excellent. Lug edges remain sharp and defined with light surface hairlines from gentle use. No deep dings or heavy impact gouges present. Strap & Buckle: The OEM black alligator strap retains its structure nicely with minor creasing on the interior lining from sitting on a watch pillow. The signed pin buckle shows light hairline marks but fastens securely.

Authenticity & Movement Health: The watch is powered by a self-winding Swiss automatic chronograph movement (Calibre 228 / ETA 2892 base with a premium Dubois-Depraz chronograph module). Verified for authenticity and performance: • Matching Serials: Yes, the movement serial number cleanly matches the factory stamping on the caseback and corresponds directly to the original 2005 warranty paperwork. • Beat Rate: Timegrapher confirms the correct 28,800 VPH (4Hz) beat rate for this high-grade automatic calibre. • Performance: Testing on a Weishi 1900 indicates a highly functional movement architecture, pulling an exceptionally clean, flat dual-line trace with zero erratic noise or missing beats. Beat error sits perfectly at an optimal 0.2ms. • Health: Dialing in at a healthy amplitude of 248° with a stable +12s/d rate, demonstrating excellent positional stability and zero signs of residual magnetism.

Specs: • Size: 35mm diameter (excluding crown/pushers) x 11.3mm thickness (wears with great wrist presence due to the prominent lug architecture). • Movement: Bulgari Calibre 228 Automatic Chronograph (ETA 2892-A2 base with Dubois-Depraz module). • Depth: 30 meters (3 ATM) • Power reserve: ~42 hours • Includes: Complete Full Set—inner leather presentation box, outer storage box, stamped original warranty booklet (dated 2005), Bulgari Certificate of Authenticity card, and instructions manual.
