Tudor Monarch Stainless Steel / Champagne Ref. M2639A1A0U-0001

The TUDOR Monarch M2639A1A0U-0001 was listed in pre-release information for the 39 mm stainless steel Monarch. This reference appears to have been replaced by reference M2639W1A0U-0001, and is unlikely to have been used for production watches. The watch has a faceted stainless steel case, an integrated two-link bracelet, and a dark champagne-color vertically brushed dial with applied Roman and Arabic numerals. It is powered by the Manufacture Calibre MT5662-2U and is certified as a METAS Master Chronometer. Its stainless steel case measures 39 mm in diameter, 11.9 mm thick, and 46.2 mm lug-to-lug, with a 20 mm lug width. The case is faceted and combines polished and satin finishes, continued across the matching bracelet. It is fitted with a stainless steel screw-down winding crown, a sapphire crystal, and is water-resistant to 100 meters. The dial is dark champagne-color and vertically brushed, with applied hour markers in a mixed layout using Roman numerals from 10 to 2 and Arabic numerals from 4 to 8. This configuration corresponds to TUDOR’s historical Error-Proof-style dial format. Time is indicated by central hour and minute hands, with a small seconds register at 6 o’clock. Inside is the Manufacture Calibre MT5662-2U, a self-winding mechanical movement with a bidirectional rotor system, small seconds at 6 o’clock, stop seconds, COSC certification, and METAS Master Chronometer certification. It measures 31.78 mm in diameter and 6.52 mm thick, uses 32 jewels, operates at 28,800 beats per hour, and provides a certified 65-hour power reserve. Its construction includes a variable inertia balance with micro-adjustment screw and a non-magnetic silicon balance spring, while its finishing includes Côtes de Genève, perlage, and an 18 ct gold inlay on the rotor. The watch is fitted with a two-link faceted stainless steel bracelet and a TUDOR T-fit clasp.
