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

Jaeger-LeCoultre: The Duometre works with two barrels thanks to one key component that's visible on the dial - the foudroyante

One barrel powers the timekeeping train, just like any watch. But at the same time, there is an extra "escape wheel" of sorts, stacked on top of the regular escape wheel. This extra escape wheel regulates the power of a second geartrain (which powers the chronograph), through a six-pronged star whee

Horological Meandering: I'll be "that guy" and share some comments

At this level of luxury (or honestly, any for that matter), I think there are some little details that deserve to be discussed or addressed, as a fruitful horological discussion. The biggest qualm I have is the tourbillon. To begin with, the tourbillon is an invention to solve problems in a pocket w
