Built to mark the opening of the Patek Philippe's new flagship production building, Ref. 6007A-001 Calatrava is a limited edition piece. It has a 40mm polished steel case and a gray-blue dial that contrasts well with the gold applied numerals and white gold, white lacquered baton-style hands. A Caliber 324 S C self-winding movement is visible through the sapphire caseback, adorned with a Calatrava cross and "New Manufacture 2019" inscription. It's finished with a gray-blue calfskin strap with white decorative seams and a fabric texture emboss that pairs well with the pattern in the center of the dial. Limited to just 1,000 examples.
