At the heart of the Royal M28600-0003 is Tudor's Calibre T603, a self-winding mechanical movement offering approximately 38 hours of power reserve. Protection is assured by a sapphire crystal above and water resistance to 100 metres (330 ft) below, while the steel screw-down winding crown bearing the Tudor logo keeps the case securely sealed.
The 41mm stainless steel case features a notched 316L steel bezel with alternating cut grooves and a polished finish, giving the watch a refined yet structured profile. The black sunray-finish dial is laid out with Roman numerals, lending the piece a timeless character that sits comfortably between sport and dress.
A five-row 316L steel bracelet completes the package, with satin-brushed external and central links contrasted by polished intermediate links, and secured by a folding clasp with safety catch. Reference M28600-0003 presents a well-considered combination of materials and detailing throughout.
