ELKA’s 2025 S Series Monochrome Editions are two time-only automatic watches created with Swiss photographer Christian Coigny for the “Noir et Blanc” exhibition in Geneva. Each came in black or white, in 36 mm or 40.8 mm, and was limited to 100 individually numbered pieces. The announced presale and price were tied to the exhibition; current availability of these specific editions is not confirmed.
What are the ELKA S Series Monochrome Editions?
ELKA Watch Co. made the Black and White editions in collaboration with Christian Coigny, whose analogue photography was presented alongside the watches at the “Noir et Blanc” exhibition. The exhibition ran at Espace Diorama in Geneva from November 4 to December 10, 2025. MONOCHROME Watches covered the launch on November 5, 2025, describing the pieces as a meeting of Coigny’s photography and ELKA’s mechanical watchmaking. Read the launch announcement or see ELKA’s collaboration page.
What differs between the Black and White editions?
The main choice is the monochrome treatment: a black or white execution, each with a matching smooth leather strap. Both versions share the same announced movement and core specifications. Each color was offered in two case diameters.
| Edition | Announced case sizes | Dial and strap | Edition limit |
|---|---|---|---|
| Black | 36 mm and 40.8 mm | Monochrome sunray-brushed dial; black smooth leather strap | 100 individually numbered pieces |
| White | 36 mm and 40.8 mm | Monochrome sunray-brushed dial; white smooth leather strap | 100 individually numbered pieces |
The launch description specifies no dial markers or track, leaving the polished hands to provide the display. The cases are stainless steel in the respective black or white execution, topped by a domed “Chevé-box” sapphire crystal. A screw-down caseback and steel pin buckle complete the described construction. For ELKA’s broader collection information, see its S Series page.
