Patek Philippe has created a totally new look for its famous split-seconds chronograph in platinum with a perpetual calendar.
Just like the 2015 Split-Seconds Chronograph Ref. 5370 model 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.
Both models are equipped with the manual-wound Caliber CHR 27-525 PS Q movement. Both indicate: Month at 3H, Day of the week at 9H, Date at 6H, Leap year at 4.30H, Day/Night display at 7.30H and Moon-phase at 12H. They also offer the split second chronograph function.
