Yes, you read that right. This changes the moment of inertia of the balance wheel, and the change is adjusted such that it compensates for the change in modulus of elasticity of the balance spring. It causes the balance wheel to oscillate with a resonant frequency when the timepiece is running, which controls the speed at which the wheels of the timepiece turn, thus the rate of movement of the hands. As the name suggests, the Parachrom hairspring is a hairspring, but in true Rolex fashion, it’s not just any hairspring. This is why most watches are equipped with a regulator on the balance cock that can be adjusted to vary the active length of the hairspring. A regulator lever is often fitted, which can be used to alter the free length of the spring and thereby adjust the rate of the timepiece. The pinion is usually fitted with a graduated silver or steel disc. The Bosley Regulator, as described above, in which the Pins are mounted on a lever pivoted coaxially with the Balance, the extremity of the lever being able to be moved over a graduated scale. The Spiromax hairspring has been improved over the years, now holding several patents for its geometry and the addition of an inner boss making it highly accurate.

Moving the regulator slides the slot along the outer turn of the spring, changing its effective length. Your email address will not be published. All-stars Swatch Group, Rolex, and Patek Philippe got together to work on a silicon hairspring in the early 2000’s in collaboration with the Suisse d’Electronique et de Microtechnique. LETAOSK Balance Wheel With Hairspring Replacement . The extremely thin, coiled spring that controls the swings, or oscillations, of the balance. By appointment only. 61,867 dated February 5, 1867. I Crafted from a paramagnetic alloy, it is unaffected by magnetic fields and up to 10 times more resistant to shocks. The modulus of elasticity of materials is dependent on temperature. From your initial contact to after you have your new watch on the wrist. A regulator lever is often fitted, which can be used to alter the free length of the spring and thereby adjust the rate of the timepiece. While the compensating balance was effective as a way to compensate for the effect of temperature on the balance spring, it could not provide a complete solution. So, let’s open the caseback and see what it’s all about. Its resonant period makes it resistant to changes from perturbing forces, which is what makes it a good timekeeping device.
