Tudor Royal Day-Date 30 Stainless Steel - Diamond / MOP Ref. M2830A1S0-0001

The Tudor Royal M2830A1S0-0001 debuted in 2026 as a 30mm stainless steel model within the updated Royal collection, combining a mother-of-pearl dial, diamond-set bezel, and a mixed display of Roman numerals and diamond-set hour markers. In the current 30mm steel range, it is one of the most elaborate executions. Its stainless steel case measures 30mm in diameter and 8.7mm in height, with alternating polished and satin-brushed surfaces. The bezel is executed in stainless steel and set with diamonds, setting this reference apart from the standard notched steel versions elsewhere in the line. A screw-down winding crown in stainless steel, signed with the Tudor shield in relief, contributes to the 100-metre water resistance, while a sapphire crystal protects the dial. As with the rest of the updated Royal family, the end-link and case relationship was also revised so the bracelet links no longer touch the case directly. The dial is executed in mother-of-pearl and arranged with Roman numerals at 6, 9, and 12 o’clock, while the remaining hours are indicated by diamond-set markers. With no calendar indications, the display is left open enough for the dial material and marker arrangement to take visual priority. That combination gives the watch a more decorative character than the simpler 30mm steel variants with full Roman numerals or stick markers. Inside is the Tudor Manufacture Calibre MT5201, a self-winding mechanical movement with 26 jewels, bidirectional winding, and a power reserve of approximately 50 hours. It is regulated to -3/+5 seconds per day on the fully assembled watch and features a variable inertia balance, a non-magnetic silicon hairspring, and a stop-seconds function for precise time setting. The integrated five-link stainless steel bracelet combines satin-brushed external and central links with polished intermediate links and closes with a folding clasp and safety catch. This version is cleaner internally. The dial paragraph now carries the decorative point once, instead of circling back to it.
