According to Patek Philippe, “The movement is a prime example of tradition paired with innovation. It combines the classic column-wheel control concept with a modern vertical disk clutch that eliminates the risk of hand jump or recoil when the stopwatch function is activated. The clutch is practically friction-free, so that the chronograph hand can be used as a permanently running seconds hand if desired.”

In-house caliber CH 28-520 IRM QA 24H has 456 total components, including 14 bridges and 40 jewels. It features a Gyromax balance wheel and a Spiromax balance spring. It beats at 4Hz and has maximum reserve of 55-hours. The central rotor is in 21K gold.

The case measures 40.5 mm in diameter and features convex sapphire crystal, along with a sapphire crystal case back. The price is $54,800.
