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

Jacques Bianchi JB200 Dive Watch Re-Edition Kickstarter
Kickstarter can be a beautiful way to launch a brand and it abounds with great and equally disappointing projects. From time to time, we see great campaigns surface and today is one of them, marked by a distinct French accent. France has a long history when it comes to watches and, specifically, dive watches. From Comex to Captain Cousteau, watches for professional divers are closely associated with the city of Marseille, on the Mediterranean Sea. Another name, less famous perhaps but no less significant has to be added to this list: Jacques Bianchi, a watchmaker whose workshop overlooks the Old Port of Marseille. In the 1980s, he created a watch specifically for these men, and today it stages a comeback. Meet the Jacques Bianchi JB200 Dive Watch Re-Edition launching now on Kickstarter.? Behind this name is a man who is now in his eighties. With his workshop next to Marseille’s port, Jacques Bianchi has known Jacques Mayol and Captain Cousteau and his secon
