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

Horological Meandering: That's a good question

For clocks, the trick is to look for any shafts that are square. This is so that you can have a good "grip" on the shaft to turn it (i.e. transmit high torque), to wind the barrel. Also, within the same area you will notice gears are made of steel, not brass. Steel is a high strength material which

A. Lange & Söhne: There are two types of Lange Balance Cocks - for regulators, and for freesprung balance wheels

Before getting into it, let's revisit some theory first to better appreciate the subtleties of why the engraving differences arise. The 1st gen Lange Chrono uses a regulator to adjust the timekeeping (beat rate). Notice the swan-neck with its screw - it pins a long needle, which is the regulator lev

Horological Meandering: I'd humbly suggest the sapphire sandwich model for a few reasons:

1. The practicality of scratch-resistance over hesalite. 2. The sapphire has a clear caseback with the Cal 1863 - which is essentially a visible and "better finished" Cal 1861 of the hesalite model. The main differences being Cotes de Geneve of the bridges, and a metal instead of a Delrin plastic br
