Roger Dubuis Excalibur Biretrograde Calendar

Roger Dubuis presents the Excalibur Biretrograde Calendar RDDBEX1179, a 40 mm case in rose gold. The dial sits under a sapphire crystal with anti-reflective coating, and the rose gold caseback is fitted with a display window onto the movement. Inside is Calibre RD840, a monobalancier movement with 60 hours of power reserve, decorated and finished to meet Geneva Seal standards. This piece belongs to a limited edition of 244 pieces. A brown calf leather strap closes with a rose gold folding clasp, also fitted with the Quick Release System for swapping straps. Rated to 100 metres, the case withstands everyday splashes and swimming without concern.
