Roger Dubuis Excalibur Stainless Steel 42mm

Roger Dubuis presents the Excalibur Stainless Steel 42mm, reference RDDBEX0793, a limited edition with a 42 mm steel case. The case measures 6.38 mm thick and pairs with a sapphire crystal treated with anti-reflective coating. Inside is the RD820SQ, a self-winding skeletonised calibre with a star-shaped bridge and a 60 hour power reserve, certified with the Poinçon de Genève. The dial's dark grey flange sits open to view, and the display back shows the finishing on the plate and bridges. Only 166 pieces exist. A steel bracelet closes with a triple folding clasp in steel. Water resistance is set at 30 metres, modest by design given the open architecture on show.
