Specifications Model: Tudor 951 Oyster Automatic Release Year: 1946 Case Material: Stainless steel Case Diameter: 34mm Dial: Aged patina with Tudor “small rose” logo Movement: Bumper automatic movement Functions: Hours, minutes, seconds Water Resistance: Oyster case sealing (vintage durability) Strap: Leather The Tudor 951 Oyster Automatic, introduced in 1946, represents one of the earliest automatic watches under the Tudor brand, founded by Hans Wilsdorf—the visionary behind Rolex. This watch was a pioneering effort, housing a bumper automatic movement, a system that predated modern full-rotor automatics. With its 34mm stainless steel case, Oyster case sealing technology, and historical significance, the Tudor 951 remains a sought-after collector’s piece. Unlike traditional modern automatic watches, the bumper movement in the Tudor 951 provides a unique tactile experience—where wearers can feel the rotor “bumping” against springs instead of freely rotating. This engineering approach was an early solution to self-winding efficiency. The Tudor “small rose” logo is another rare branding mark seen on early models before transitioning to the shield emblem. The Oyster case, originally developed by Rolex, grants superior water resistance, making the watch both practical and historically significant. The 34mm stainless steel case features a screw-down case back, ensuring durability and protection against moisture and dust. The clean dial layout develops a rich patina over time, enhancing its vintage appeal. The Tudor “small rose” emblem sits below 12 o’clock, alongside gold-tone hour markers and dauphine hands, reinforcing the watch’s refined aesthetic. While many surviving examples are fitted with leather straps, the model originally featured a riveted stainless steel bracelet, which collectors highly covet today. The Tudor 951 is powered by an early bumper automatic movement, a design that represents a transitional phase in automatic watchmaking. Unlike modern full-rotor automatics that spin freely in both directions, the bumper system features a weighted rotor that moves within a restricted arc, “bumping” against a pair of springs at either end of its travel. This mechanism helps to wind the mainspring while minimizing friction and wear. The bumper movement was a precursor to the more advanced Perpetual rotor used in later Rolex and Tudor watches. While not as efficient as modern self-winding mechanisms, it provided a significant improvement over manual-wind watches at the time. Collectors appreciate the distinctive feel of the movement when worn—subtle but noticeable feedback from the rotor hitting the springs. The Tudor 951 Oyster Automatic was among the first automatic watches produced by Tudor under Rolex’s influence. It bridged the gap between early manually wound Oysters and later fully automatic Tudor models. The use of Rolex’s case technology and branding elements makes it an important piece in Tudor’s evolution. It also reflects the post-war era’s innovations in watchmaking, when brands were experimenting with self-winding technology to improve convenience and reliability. Despite its vintage status, the Tudor 951 remains a highly wearable timepiece. The Oyster case provides water resistance, ensuring durability in daily use. Its mid-century 34mm size makes it a comfortable choice for collectors who appreciate classic proportions. The tactile nature of the bumper movement adds a unique connection between the wearer and the watch, reinforcing its charm beyond aesthetics. The Tudor 951 Oyster Automatic is an important piece of horological history, bridging Rolex’s pioneering spirit with Tudor’s growing identity. Whether for its mechanical novelty, vintage appeal, or collectibility, this watch remains a must-have for enthusiasts. As one of Tudor’s earliest automatics, it stands as a testament to the brand’s journey toward independence and technical refinement. Ready to wear . Comes with Tudor travel pouch. |
