Bulgari’s Serpenti Seduttori 103902 extends diamonds across its rose-gold bracelet

Reference 103902 is the more gem-intensive of Bulgari’s 2026 Serpenti Seduttori automatics. Its 34mm rose-gold snake-head case surrounds a white opaline dial, while the bezel is set with 36 round brilliant-cut diamonds. Another 117 brilliant-cut diamonds form a demi-pavé pattern across the supple scale-inspired bracelet, balanced by a pink-rubellite cabochon in the crown.

Bulgari’s in-house Lady Solotempo BVS100 automatic movement supplies hours, minutes, seconds and a 50-hour reserve. The watch is water-resistant to 30 metres and uses a folding bracelet clasp. Rather than hiding the mechanics beneath jewellery alone, Bulgari gives the watch a transparent caseback, making the calibre part of the composition. The Belgian retail price was listed at €59,300 including taxes.
