The Annual Calendar Chronograph 5905R-010 has been designed to embody elegance and functionality in perfect harmony. Crafted in rose gold, this timepiece has been equipped with a sophisticated annual calendar mechanism that automatically accounts for months with 30 or 31 days.

The chronograph function has been seamlessly integrated, allowing accurate time measurement while maintaining the watch’s sleek aesthetic.

The dial, in a rich sunburst brown, has been meticulously arranged to ensure clarity, with the day, date, and month displayed in three apertures for easy reading. The self-winding movement, visible through the sapphire crystal case back, has been finely tuned for precision and reliability.

This model has been created to meet the highest standards of craftsmanship and durability, making it a versatile addition to any collection. The 5905R-010 stands as a testament to Patek Philippe’s commitment to both innovation and timeless design.
