JB Roger Dubois Excalibur King Series RDDBEX0260 (Sport Version of RDDBEX0393, 45mm Diameter, Safety-Covered Bridge & Crown, Includes Original-Style Winding Box)

A meticulously crafted replica—the most authentic openworked tourbillon wristwatch ever produced. Built upon a genuine tourbillon movement, it faithfully replicates the complete architecture of the original RD505SQ integrated tourbillon caliber: balance wheel and tourbillon cage feature identical regulating screws (timing screws), sword-shaped hands are precisely reproduced, and overall movement similarity reaches 98%. It features the same safety-cover crown and an upgraded, fully enclosed folding clasp as the authentic piece. Not a single component is omitted nor added—the movement’s structure is an exact mechanical match. For precise visual reference, consult official images on WatchHome.com (China’s leading watch portal). Sapphire crystal anti-scratch glass; original-style folding clasp. Bold, elegant, and ultra-trendy—exuding exceptional sophistication and charisma; an essential timepiece for stylish, affluent, and confident men. A new horological icon following Richard Mille’s tourbillons and Roger Dubois’ Excalibur Double Tourbillon. Manufactured exclusively by JB Factory—specializing in premium-tier tourbillon replicas.
