Tudor
chronographe heritage racing - Blue Opaline Full Set

Tudor Chrono Blue chronograph reference M70330B-004 from 2018, part of the new Tudor Heritage series inspired by the Seventies. A pre-owned collectible Full-Set watch, 42 mm in diameter, in satin-finished and polished 904L steel, in near mint condition.

This 150m water-resistant chronograph features a bidirectional rotating bezel with a twelve-hour scale. It allows tracking of a second time zone, offering a sporty alternative to a traditional GMT watch. Powered by a self-winding mechanical chronograph movement, it’s ideal for motorsports thanks to its 55-jewel Calibre 2892 with a 2054 module manufactured by Dubois-Depraz—specifically designed to absorb shocks and vibrations while supporting the chronograph function. Screw-down pushers ensure secure operation, preventing unintentional stops due to mishandling or impact.

The dial is two-tone, with a dominant opaline blue over a vanilla background. The two sub-dials echo the color codes of the Racing series Tudor chronographs from the 1970s, dedicated to motorsports. Baton-shaped black luminous hour and minute hands ensure optimal legibility, while the central seconds hand is orange-tipped. A date window sits at 6 o’clock, all protected by a flat, scratch-resistant sapphire crystal without a cyclops lens. The Tudor shield logo is positioned above the "Tudor Genève" branding and also appears on the winding crown.

All in all, this is a stunning high-end watch with a vintage aesthetic combined with modern watchmaking excellence: a robust, reliable, and precise movement running at 28,800 vibrations per hour, with a 42-hour power reserve. It features Stop & Go chronograph functionality with locking pushers, similar to the Rolex Daytona. The watch includes a 12-hour graduated rotating bezel and a deployant clasp with a safety catch. Note that both original straps are included in the set: a Heritage Blue NATO strap with vintage styling, and a 904L steel bracelet with all removable links, making it suitable for wrists of all sizes.
