Year In Review: What A Year For Chronographs! Here’s The Best In Technical Innovation From Omega, MB&F, And More
But, like the rest of the watches here, it’s what’s on the inside that counts. While you can read our fully-technical introducing post for more information, I’ll sum it up as succinctly as possible. Patek’s new movement is the CH 29-535 PS 1/10, based on the 2009 rattrapante chronograph caliber CH 29-535. The 1/10 second and normal chronograph hands sit together at zero, then depart when the pusher is depressed, running at different rates across the dial. The original rattrapante mechanism had to be reconfigured, starting with the escapement and oscillator, with the 1/10th hand driven off the fourth wheel of the movement. In some ways, the watch is like MB&F in that there are essentially two separate chronograph mechanisms inside the 5470P, but with an entirely different – and still incredibly impressive – result.
