Sellita SW220 Automatic Movement

The watch is powered by an Anthracite Sellita SW220 automatic movement with 26 jewels and an Incabloc® shock absorber. The self-winding movement provides hours, minutes and seconds, together with a bilingual day and date calendar. Rapid Day Date Correction allows the day and date to be adjusted easily. The movement is hand-assembled in La Chaux-de-Fonds, Switzerland.

Unidirectional 60-Minute Dive Bezel

The Anthracite JDD features a unidirectional 60-minute dive bezel for measuring elapsed time. The 316L stainless steel case has an Anthracite finish with black anti-reflective Ion-Plating (IP) armour, while the screw-down crown and sapphire crystal contribute to its 30 ATM water resistance, rated to 300 metres (1,000 feet).
