The Delphis Sub Zero is a limited edition of 50 pieces within the Delphis collection. It is housed in a 42mm stainless-steel case finished with a blue CVD coating and paired with a matching blue rubber strap. The case design follows the established Delphis proportions and accommodates the brand’s distinctive display architecture. The dial is constructed in multiple layers. The upper crescent, which carries the retrograde minute and jumping hour indications, is finished in silver galvanic treatment and features a curved, hand-guillochéd surface. Below it, the small seconds display is positioned on a curved subdial, CVD-coated in blue and also hand-guillochéd. Both dial elements are produced in-house at the Chronoswiss Atelier in Lucerne. Powering the Delphis Sub Zero is the Chronoswiss Manufacture Calibre C.6004. The movement supports the jumping hour and retrograde minute functions and is designed to deliver consistent performance and reliability. Produced in a numbered series of 50 examples, the Delphis Sub Zero continues Chronoswiss’ approach of combining traditional decorative techniques with contemporary case materials and movement architecture.
