Soprod is a movement manufacturing house based in Switzerland. Today, Soprod is most well-known for their ETA clone/compatible movements, but the company started making watch parts in Tramelan, Switzerland in 1966. At one point in their history, Soprod was a contract movement maker (like Sellita), assembling movements for companies like ETA. In 1984, the former Chief of Production at Swatch (Victor Bruzzo), left and registered his own company called Indtec. While officially registered as being a Scion, Switzerland based company, […]

What is rebanking in watches? Rebanking or knocking (sometimes referred to as knocking the banking) occurs when the pallet fork horns (prongs) hit the impulse pin. Here is how the dictionary defines it: “A malfunction in a watch caused by excessive balance motion that makes the roller jewel strike outside the fork horns and renders the escapement inoperative —distinguished from overbanking” –source What does rebanking sound like? The quick video above gives an audible example of what it sounds like […]

What is a mecaquartz watch? Mechaquartz or meca-quartz typically refers to a chronograph watch movement that uses quartz technology for the main timekeeping functions of the watch, with a mechanical module for operating the chronograph – giving it a smooth sweeping like motion (similar to an automatic watch) and a snap-back style return to zero when resetting the chronograph. That is why these are often called hybrid movements – but is a hybrid movement different than a mecaquartz? Is a […]
If you’ve been in the Caliber Corner Community for some time, you’ve seen the word lignes here and there. What does it all mean? What is a lig-nez?! Lignes is the French word for lines (and pronounced the same way), a unit of measurement for watch movements. Although most watch movements will have the diameters listed in millimeter (mm), you may also see linges listed – especially when dealing with raw movements. Here is a brief history from Wikipedia: The […]

Cymaflex is a proprietary anti-shock device found in vintage Cyma watches. “Cymaflex” can cause caliber confusion because the name of the anti-shock device is sometimes also the name of the watch. It may be difficult to find individual Cymaflex components, therefore, if you are in need of parts, you may have to purchase a movement or watch for parts/repair. Sometimes there are sellers on eBay parting out old Cymaflex watches. In Cyma’s own words: “Shocks are the greatest enemies of […]

The amplitude (AMP.) of a watch movement indicates sufficient energy transmission. Amplitude is found by measuring the rotation in which the balance wheel of a running watch swings back and forth. It is measured in degrees and is a great way to check the mechanical health of your watch, and more specifically the mainspring’s ability to deliver needed power. This is how Witschi, a well-known Swiss manufacturer of testing equipment, describes amplitude in their documentation: The amplitude is the angle […]
