Annual Calendar 38.5mm Moon Phases White Gold

The exceptional Patek Philippe Ref. 5396G-011 showcases the manufacturer's dedication to practical complications through its acclaimed annual calendar mechanism in an elegant dress watch execution. This sophisticated 38.5mm reference in lustrous 18K white gold features a balanced dial layout with central date hand and symmetrically positioned day/month apertures at 12 o'clock—a distinctive arrangement inspired by Patek's historic triple calendar models from the 1940s and 1950s. The silvery opaline dial with gold applied hour markers creates perfect legibility across its multiple calendar displays.

Inside beats the self-winding caliber 324 S QA LU, featuring annual calendar mechanism displaying day, date, month, and moon phase with legendary precision. The annual calendar system operates through an ingenious mechanical solution requiring just 154 components, compared to over 200 in traditional perpetual calendars. The innovative mechanism requires adjustment only once yearly at the transition from February to March. The exclusive 21K gold rotor ensures efficient winding, while the decoration includes Geneva striping, chamfered bridges, gold-filled engravings, and circular côtes de Genève—exemplifying Patek's commitment to traditional finishing techniques.

Master Luxury offers this preowned annual calendar in excellent condition. The black alligator strap with matching 18K white gold deployant clasp completes the reference's refined aesthetic. This distinguished timepiece bridges the gap between simple calendar watches and perpetual calendars, combining practical functionality with architectural symmetry rarely found in complicated timepieces. For collectors appreciating both technical sophistication and classical design principles, this reference delivers exceptional value within Patek's calendar watch category.
