The watch includes a transparent case back and sapphire crystals. It is powered by a manual-wind movement featuring blued bridges, 17 jewels, a lateral lever escapement, and a visible one-minute tourbillon regulator with a brushed steel cage. Notable movement features include an open main spring with wolf tooth winding, a monometallic balance, and an index regulator. The dial is transparent with applied Arabic numerals and luminous bâton hands. The watch is worn on a black leather strap secured by a stainless steel Jorg Hysek deployant clasp.

Object description

Case and Dial Design

The watch is housed in a rectangular four-body case measuring 51 x 41 mm with a thickness of 15 mm. The construction utilizes 18K white gold that has been both polished and brushed. The aesthetic is heavily embellished with a total of 321 diamonds integrated into the design, complemented by curved sides and transparent case back.

The dial is transparent, allowing for visibility into the movement, and features applied Arabic numerals. The time is indicated by luminous bâton hands, which maintain legibility against the complex backdrop of the movement plates and tourbillon cage.
