This 39mm sports watch combines stainless steel with yellow gold accents for a refined two-tone appearance. The case houses a silver dial with matching gold hands, whilst the fixed bezel and screw-down crown are also finished in yellow gold. Water resistant to 100 metres, it sits on a polished and satin-finished steel and gold bracelet secured by a folding clasp with safety mechanism.
The watch is powered by Tudor's Manufacture Calibre MT5602, a self-winding mechanical movement with bidirectional rotor achieving COSC certification. The movement delivers a 70-hour power reserve. A flat sapphire crystal protects the dial from scratches, and the yellow gold crown bears the Tudor rose motif in relief.
