F.P. Journe: 32 refers to the maximum number of unique hour representations you can do with just five fingers

With one finger, you can represent a max of two different numbers (up and down). With two fingers, you can represent four numbers max (2x2). Eight numbers max with three fingers (2x2x2). Sixteen numbers max with four fingers (2x2x2x2). and finally, thirty-two unique numbers max with five (2x2x2x2x2)

A. Lange & Söhne: The cut-out in the reset lever makes it act like a detent "spring" and allows some bending - think of it as a little shock absorber, when you press the pusher.

To be more precise, it acts as a shock absorber between the reset hammer (like in a chronograph), and a second lever which disengages the vertical clutch that drives the seconds hand. Probably acts as a buffer/safety for slight tolerance issues, so that the vertical clutch doesn't get damaged in the

Montblanc: As a matter of fact, you are correct - The pocket watches weren't symmetrical!

I did a quick search and found this article from timeandwatches , which has some scans of past Minerva watches. One of the photos show a rattrapante pocket watch, which does indeed, have the top subdial sitting slightly higher up than the lower one! (I verified it by measuring the photo digitally) I

Audemars Piguet: There are some 777 movements with defined interior angles, but there doesn't seem to be a pattern with the varying levels of finish

This example below, taken from the deconstruction by The Naked Watchmaker , showcases two defined interior corners on the 777 movement. While admittedly not the cleanest execution, shows some of the effort needed by hand to execute the anglage. The anglage also appears to be wider and more rounded.

Audemars Piguet: This is not necessarily true anymore, unfortunately

In some 5177 movements (I'm unsure if this applies to all new 777Qs), the interior angles are now replaced by rounded ones which are likely done by machine. This can be seen in this video at 0:41, officially from Breguet: Regards, skyeriding

Independents: The clickspring is integrated inside the crown wheel itself - just barely visible in the last photo.

Two clicks are fixed to the inner ring of the crown wheel, which both interact with a fixed star wheel/ratchet hub. The hub itself can freely rotate slightly, as it has two radial track/grooves. This allows for the "slack" to prevent overwind of the mainspring at its fully-wound limit, just like a r

A. Lange & Söhne: Are you adjusting the time backwards near midnight? I'm not fully familiar with the L121.1 bigdate mechanism if it has one-way safety features,

,but that might be one possible reason. If the grinding happens at anytime elsewhere, then I'm not sure and would need a watchmaker to ascertain. Regards, skyeriding
