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

Horological Meandering: For the tourbillons, technically, I prefer the VC Overseas. Here's why:

First, let me say that its nice to see that both AP and VC tourbillons here have an overcoil hairspring, which encourages concentric breathing of the spring and gives better isochronism (i.e. the timing is constant regardless of of the varying power as the mainspring unwinds). Lower-end tourbillons

Horological Meandering: Short answer: no. Long answer: ...

EDIT: I misread the question and thought the intention is to compare the column wheel with the cam chronograph. In that case, they do not really affect the hour recorder, as they mainly manipulate the mechanisms for the seconds and minute counter. But to directly answer your question, not too compli
