At 41mm, the Royal wears a round stainless steel case with both polished and satin finishing. A notched yellow gold bezel with alternating cut grooves frames a sapphire crystal, while a yellow gold screw-down winding crown stamped with the Tudor logo adds a refined contrast at the side of the case. Water resistance reaches 100 metres (330 ft), making this a versatile everyday companion.
The silver sunray-finish dial is laid out with Roman numeral hour markers, lending the Royal a classically proportioned look. Powering the watch is the self-winding mechanical Calibre T603, offering a power reserve of approximately 38 hours.
The bracelet combines center links in steel alongside links capped with a 0.2mm layer of yellow gold, secured by a folding clasp with safety catch — a detail that echoes the two-tone character carried throughout the reference M28603-0001.
