Fiftysix Self-Winding – High-Grade Stainless Steel Chassis Architectured Within a Mid-Century Retro Blueprint

The structural case framework projects absolute aesthetic authority through its fluid circular contours, achieving a perfectly proportioned 40 mm diameter scale and an elegant dress thickness profile of 9.6 mm to ensure uncompromised daily comfort. The entire integrated body and polished fixed bezel are masterfully sculpted from premium Stainless Steel—combining high-performance durability with a refined, sharp masculine aesthetic. The architectural design codes honor the legendary 1956 reference 6073, seamlessly integrating the stepped lugs whose profiles represent the four branches of the Maltese Cross emblem.

Elevating its vintage charisma, the container is topped with a historic box-type sapphire crystal that rises prominently above the bezel rim, mimicking the curved plexiglass domes of ancestral horology while providing superb optical distortion-free viewing. The reverse exhibition window exposes the hand-decorated mechanical execution of the movement. The high-grade structural container is securely sealed against dust and moisture to satisfy a daily-resilient 3 bar (30 m) water resistance, executing a flawless bridge between mid-century heritage and modern engineering.

Sophisticated Double Finished Grey Sector Façade Paved with Blue SuperLuminova

The visual dial canvas is beautifully laid bare across its highly customized, grey-toned face, utilizing a complex sector dial layout that divides the timekeeping landscape into concentric zones of contrasting textures for optimum scannability. The central focal area presents an understated matte opaline texture, while the outer chapter ring segment is finished with a striking sunburst satin-brushing that shifts dynamically from cool slate to shimmering platinum charcoal under direct light.

Ensuring micro-readability and high scannability, the track combines applied 18K gold baton index points with alternating bold Arabic numerals, framed by a traditional internal railway-type minute track. The absolute nocturnal legibility is driven by solid gold baton hands and indices heavily inlaid with a premium blue SuperLuminova® compound that radiates a sharp, brilliant luminescence in zero-light tracks. The temporal indicator array is cleanly punctuated by a matching date aperture positioned at 3 o’clock, maintaining absolute aesthetic equilibrium across the dial face.

Manufacture Caliber 1326 Engine – Self-Winding Core with 22K Gold Maltese Rotor

Ensuring absolute operational precision and tactile authority is the mechanical self-winding movement, Caliber 1326, calculated, constructed, and hand-decorated entirely within the highest specifications of fine watchmaking. Composed of 142 individual components and 25 jewels, this high-performance engine operates at a frequency of 28,800 vibrations per hour (4 Hz) with a movement thickness of 4.3 mm, supplying a trusted 48-hour power autonomy. The caliber integrates an advanced balance-stop mechanism for micro-precision temporal adjustments when synchronizing the sweeping central seconds display. The reverse view window reveals bridges chiseled with meticulous Côtes de Genève wave patterns, framing a magnificent openworked oscillating weight sculpted from solid 22K gold, shaped into the geometric silhouette of the historic Maltese Cross.
