The Studio Underd0g x Massena LAB 03SERIES Champagne & Caviar is a limited-edition monopusher chronograph which celebrates all things extraordinary and excessive, with a design that pairs the subtle shimmer of champagne tones with the inky richness of caviar.
By employing modern machining techniques, the oversized "big-eye" sub-dial at three o'clock has been artfully reimagined to resemble a (generously portioned) pot of caviar, a subtle yet striking detail that defines the design. The varied size of the sub-dials is visually offset by the co-branding, allowing the chronograph seconds hand to pass through uninterrupted. Idiosyncratic, yet balanced. A keen eye will notice the distinct silhouette of a champagne bottle at the base of the chronograph hand, sweeping smoothly over the shimmering champagne dial.
Housed within the three-part case construction—and visible through its exhibition caseback—is the Swiss Sellita SW510 M. This monopusher, hand-winding calibre beats at 28,800 vph (4 Hz); features 63 hours of power reserve; and a custom Côte de Genève, ruthenium-anthracite-finished bridge exclusively made for Studio Underd0g.
Cased in 316L stainless steel measuring 38.5mm, with a lug-to-lug measurement of only 44.5mm, the Studio Underd0g x Massena LAB 03SERIES Champagne & Caviar is flattering to a variety of wrist sizes. On the dial side, the watch is fitted with a double-domed sapphire crystal, while the exhibition caseback is fitted with a flat, box sapphire crystal.
The Studio Underd0g x Massena LAB 03SERIES Champagne & Caviar, limited to only 200 pieces, is priced at £1,750 / $2,200 / €1,800 and will be offered exclusively via underd0g.com from 3pm GMT on November 11, 2025.
