"Almost exactly the same but executed with more finesse, the pocket watch is a perfect tribute to turn-of-the-19th century watchmaking."

A delightfully in-depth look at Philippe Dufour's Grande Sonnerie Pocket Watch No. 1 by JX Su, Sheng Lee, & Richard Lee.

One thing that has perplexed me about Philippe Dufour's Grand Sonnerie in the past, which this article addresses tangentially, is how Philippe would go about letting down the power in each of the gear trains when working on this piece—both in development and later on each time it required service. As it turns out, the satellite ratchet system nested into each of the ratchet wheels is not the full story. The visible ratchet system solely governs winding direction, similar to the way a pair of reversers would operate in an automatic winding system. Beneath these ratchet wheels is another set of clicks, which are responsible for holding the power in the barrels, and it is these clicks that a watchmaker would disengage to let down the power in a controlled manner. It's a masterful solution to a complex problem, in a masterfully complex watch.

The sun indicator, crafted from a ferriferous mineral known as bronzite, lends this piece an extra bit of depth and character.

Debuting in the new Royal Oak Extra Thin, this caliber improves on its predecessor, the AP 2121, in a number of significant ways.

I am incredibly happy to see the barrel get a dedicated bridge. Previously, in the caliber 2121 (itself based on the Jaeger-LeCoultre 920), if there were any issues with the barrel, such as a broken mainspring, nearly the entire movement would have to be disassembled to address it. Mirroring it handsomely on the other side, I am pleased to see this caliber also make the move from a balance cock to a full balance bridge. The move from peripheral automatic winding to a centrally driven system, mounted on ball bearings, is a likewise welcome change.

I am curious to learn more about the specifics of the implementation of the new stud holder. Ostensibly, the mechanism to move the stud holder, in order to adjust the beat error, appears to be mildly over-engineered and the screw to lock in the beat error once corrected is precariously close to the soft metal of the balance bridge.
