A charming example of one of Rolex’s most historically significant early automatic wristwatches, this stainless steel reference 4392, part of the celebrated “Bubble Back” family combines technical ingenuity with elegant Art Deco aesthetics. Produced in the 1940s, these models marked Rolex’s pioneering transition into fully-waterproof and self-winding wristwatches, forming the foundation of the Oyster Perpetual line as we know it today.

The dial is an exquisite highlight of this example, showcasing a beautiful two-tone silver and cream design with a contrasting circular central field most probably reprinted, we cannot guarantee the originality of the dial. The applied Breguet numerals, rendered in a refined, stylized form, elevate the watch with a strong vintage character rarely seen in Rolex production after this period. The small-seconds subdial at 6 o’clock, framed by a precision minute track, completes a layout that feels both technically driven and artistically executed.

The polished Oyster case retains the rounded, compact proportions typical of the Bubble Back architecture, its thickness a direct result of the early self-winding mechanism housed inside. Paired with a desirable and hard-to-find period “Big Logo” steel bracelet, the watch presents an authentic and cohesive aesthetic, still deeply connected to its era.

Its serial number 607'544 corresponds to mid-1940s production, a particularly appealing period for collectors seeking strong originality and early Oyster engineering. Light, honest wear confirms a life of careful enjoyment, while preserving the integrity and vintage charm that make authentic examples so collectible today.

Early Rolex Bubble Backs like this one featuring Breguet numerals, a well-preserved two-tone dial, and a historically correct bracelet occupy a special place in the brand’s evolution and continue to rise in appreciation among connoisseurs of early Rolex craftsmanship. A delightful and historically resonant acquisition for the discerning vintage enthusiast.
