Anchoring the Royal's design is a round 41mm stainless steel case with a polished and satin finish, topped by a sapphire crystal. The notched bezel is rendered in yellow gold with alternating cut grooves and a polished finish, while the screw-down winding crown — also in yellow gold and engraved with the Tudor logo — reinforces the watch's refined two-tone character.
The champagne sunray-finish dial is laid out with roman numerals, lending the piece a classically proportioned look. Powering it all is the self-winding mechanical Calibre T603, offering a power reserve of approximately 38 hours, with water resistance rated to 100 metres (330 feet).
The bracelet combines steel center links alongside links covered by a 0.2mm yellow gold cap, secured by a folding clasp with a safety catch — a considered construction detail that ties together the overall two-tone aesthetic of reference M28603-0004.
