In-house design studio

Historical significance
Bulgari Serpenti 38 mm Slate Grade sits within Bulgari's Serpenti line, introduced in 1970. It carries the house codes established since 1884 — grade 5 titanium case, slate grey dial and in-house manual-winding — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

Brand history
Bulgari has spent more than 142 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Octo Finissimo, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Sotirio Bulgari established Bulgari in 1884, working from Italy at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Bulgari calibre produced today.
