About this reference

A nocturnal window on infinity, the DB28 Skybridge features a whole host of astonishing shimmering effects, in turn brilliant or intensely radiant with the blue that has been a House signature from its creation. An eminent reference to the famous 18th century clocks, this star-studded sky derives its power and beauty from its concave shape and its multiple decorations crafted in the company workshops.
