Tudor Royal Day-Date 30 Stainless Steel / Blue Diamond Ref. M2830A1A0-0001

The Tudor Royal M2830A1A0-0001 debuted in 2026 as a 30mm stainless steel model within the updated Royal collection, combining the line’s integrated bracelet architecture with a blue dial and a mixed display of Roman numerals and diamond-set hour markers. Within the current Royal family, this reference stands apart through that dial layout, which gives the smallest case size in the range a more decorative character while retaining the collection’s compact, integrated profile. Its stainless steel case measures 30mm in diameter and 8.7mm in height, making it the slimmest execution in the updated Royal line. The case is finished with alternating polished and satin-brushed surfaces and fitted with the revised notched bezel design introduced for this generation, giving the watch a sharper external profile than earlier Royal models. 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 case and end-link relationship was also revised so that the bracelet links no longer contact the case directly. The dial is executed in blue and arranged with a combination of Roman numerals and diamond-set hour markers, giving it a more elaborate visual structure than the standard full-numeral or baton-marker layouts elsewhere in the range. In the 30mm Royal, the absence of both day and date indications results in the cleanest overall display architecture in the family, allowing the marker configuration and dial colour to play a larger role in defining the character of the watch. The blue dial introduces a stronger sense of colour, while the mixed marker layout adds a more decorative dimension without changing the underlying simplicity of the time-only format. Inside is the Tudor Manufacture Calibre MT5201, a self-winding mechanical movement with bidirectional rotor system, 26 jewels, and a power reserve of approximately 50 hours. It is regulated to a tolerance of -3/+5 seconds per day on the fully assembled watch and incorporates a variable inertia balance, a non-magnetic silicon hairspring, and a stop-seconds function for precise time setting. The bracelet is the Royal’s integrated five-link steel design, with satin-brushed external and central links, polished intermediate links, and a folding clasp with safety catch. In this 30mm blue-dial configuration, the uninterrupted transition from case to bracelet remains central to the watch’s identity, while the mixed numeral-and-diamond display gives the reference a more jewel-like presence within the broader Royal family.
