Surrounding the dial is a fully-brushed stainless steel case, complete with a double-stepped bezel and drilled lugs. Proportions are compact, with a 38.5mm diameter, 9mm thickness, and 45.6mm lug-to-lug. The exhibition caseback features the Monochrome logo and “Montre de Souscription” engravings, a familiar sight from the first Monochrome Habring². It all frames Habring’s Calibre A11S, with the jumping-second mechanism in full view. It’s finished in the classic Habring² style, with circular brushing, perlage, and blued screws.
