Balance
Wristwatch Balance
The beating heart of a mechanical watch movement is the balance. Fed by the energy of the mainspring, a tirelessly oscillating little wheel, just a few millimeters in diameter and possessing a spiral-shaped balance spring, sets the rhythm for the escape wheel and pallets with its vibration frequency. Today the balance is usually made of one piece of antimagnetic glucydur, an alloy that expands very little when exposed to heat.
Anti-Reflective
Dubey Schaldenbrand Anti-reflection
A film created by steaming the crystal to eliminate light reflection and improve legibility. Anti-reflection functions best when applied to both sides of the crystal, but because it scratches, some manufacturers prefer to have it only on the interior of the crystal. It is mainly used on synthetic sapphire crystals. Dubey & Schaldenbrand applies anti-reflection on both sides for all of the company’s wristwatches such as this Aquadyn model.

Automatic Winding
IWC Automatic Caliber 50611
A rotating weight, set into motion by moving the wrist, winds the spring barrel via the gear train of a mechanical watch movement. Automatic winding was invented during the pocket watch era in 1770 by Abraham-Louis Perrelet, who created a watch with a weight swinging back and forth (that of a pocket watch usually makes vertical movements contrary to a wristwatch). The first automatic winding wristwatches, invented by John Harwood in the 1920s, utilized so-called hammer winding, whereby a weight swung in an arc between two banking pins. The breakthrough automatic winding movement via rotor began with the ball bearing Eterna-Matic in the late 1940s, and the technology hasn’t changed fundamentally since. Today we speak of unidirectional winding and bidirectionally winding rotors, depending on the type of gear train used.
