About the Patek Philippe Regulator 5235/50R-001 The Patek Philippe Regulator 5235/50R-001 is a unique luxury timepiece that stands out with its distinct design and technical brilliance. Crafted with a 40.5mm rose gold case, it features a sophisticated mix of polished and satin-brushed finishes, making it versatile for both formal and casual occasions.

What makes this watch particularly special is its regulator-style dial layout, which separates the hours, minutes, and seconds into their own sub-dials for excellent legibility and a refined aesthetic. The dial itself boasts a striking two-tone graphite and ebony black design, with the satin-brushed center radiating outward and matte black sub-dials enhancing readability. This layout is inspired by traditional regulator clocks, adding both functional clarity and visual appeal. Underneath its elegant exterior, the Regulator is powered by the in-house 31-260 REG QA movement, an automatic annual calendar designed for precision and reliability. This movement, visible through the case back, features an off-center mini-rotor and Patek Philippe's signature high-quality mechanics, including a Pulsomax escapement and Gyromax balance. With a power reserve of 38 to 48 hours, the watch ensures accurate timekeeping and requires minimal adjustment. Measuring just under 10mm in thickness, the Regulator is slim enough to wear comfortably under a cuff, making it both a stylish dress watch and a distinctive everyday accessory. The black leather strap and rose gold pin buckle offer a secure and elegant fit, adapting well to various wrist sizes.
