Tudor Black Bay Pro

The Tudor Black Bay Pro M79470-0004 is a GMT watch with a 39mm steel case. The case measures 14.6mm thick and carries a 20mm lug width. A domed sapphire crystal sits over the opaline dial, and the fixed bezel has a satin-brushed steel finish with a 24-hour graduated scale. Inside is the manufacture calibre MT5652, a self-winding chronometer movement with a power reserve of approximately 70 hours. The GMT function works alongside a central seconds hand, and the hands and indices carry luminous treatment for legibility. The screw-down crown is steel with the Tudor rose in relief. A riveted steel bracelet with polished and satin finish closes with a folding "T-fit" clasp. Screwed down, the crown keeps the case sealed to 200 metres.
