Patek Philippe Gondolo 5135G-010

Patek Philippe Gondolo Calendario (Ref. 5135G-010) is a distinguished annual calendar timepiece characterized by its art-deco inspired "cushion" or tonneau-shaped case. Crafted from 18k white gold, the case measures approximately 38mm. Its slate grey dial features a central guilloché pattern, white gold dauphine-style hands, and a combination of applied arrowhead indices and Arabic numerals at 3 and 9 o'clock. The sophisticated annual calendar complication is displayed through three distinct apertures: day between 10 and 11, date at 12, and month between 1 and 2 o'clock. At the 6 o'clock position, a sub-dial houses a moon phase display integrated with a 24-hour day/night indicator. Visible through the sapphire crystal exhibition caseback is the self-winding Calibre 324 S QA LU 24H, which features a 21k gold rotor and provides a 45-hour power reserve.
