The dilemma of Constant Force in Watchmaking - Monochrome Watches
Constant force is a holy grail of watchmaking and chronometry. The varying driving force delivered to the regulating organ of watches affects their rate, because balance wheels are not perfectly isochronous - isochronous means that the period of oscillation is independent of the amplitude of oscillation. Modern barrels and the Swiss lever escapement offer satisfactory regularity. Still, in their ongoing search for precision, watchmakers are showing renewed interest in taming power even further. Here is our technical guide to the complex concept of constant force.The barrel is the device that stores energy in a watch movement. It contains the mainspring coiled around the barrel arbor, which is put under tension to power the movement. The force delivered by the barrel is irregular. Strong torque is provided when it is fully wound, then it slowly wanes throughout the power reserve duration. This affects the rate of watches because balance wheels are not perfectly isochronous. The period o

Mechanical depth gauge - Monochrome Watches
A few years ago IWC was the first Swiss watch brand to make a high end mechanical watch with a mechanical depth gauge, the famous IWC Deep One. I can still remember the first time i saw that watch, it was for me the most beautiful divewatch i’d ever seen. And i guess untill this day it’s one of my favorite dive watches.Unfortunately IWC doesn’t produce them anymore, because the mechanical depth gauge gave them quite some trouble as i understood it. Now since last year there are some new high end watch brands bringing out a divewatch with a mechanical depth gauge, Panerai and Jaeger LeCoultre.
