Tudor - M2639A1A0U-0001 Monarch Stainless Steel / Champagne

Tudor M2639A1A0U-0001 description

The TUDOR Monarch M2639A1A0U-0001 debuted in 2026 as a 39 mm stainless steel model, introducing the Monarch name to the current TUDOR collection with a faceted case, integrated two-link bracelet, and dark champagne-colour dial. It combines a new external design with the Manufacture Calibre MT5662-2U and METAS Master Chronometer certification.

Its stainless steel case measures 39 mm in diameter, 11.9 mm in thickness, 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 metres.

The dial is dark champagne-colour 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 the historical Error-Proof dial format. The display consists of central hours and minutes with a small seconds register at 6 o’clock.

Inside is the Manufacture Calibre MT5662-2U, a self-winding mechanical movement with 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 in thickness, 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.
