PATEK PHILIPPE PERPETUAL CALENDAR  SPLIT-SECONDS MONOPUSHER CHRONOGRAPH

has created a totally new look for its famous split-seconds chronograph in platinum with a perpetual calendar. Just like the 2015 Ref. 5370 and the 2016 Ref. 5374, it comes in a round platinum case with a concave bezel as well as countersunk and satin-finished flanks. The dial in gold with a blue sunburst pattern or in vertically satin-finished rose gold also presents a subtly reworked appearance. It is a harmonious blend of sophisticated technology, elegance, and readability.
