Even before the invention of the material Glucydur and the construction of a Glucydur balance, it was clear to every watch connoisseur: the heart of a mechanical watch is the system around the balance. The better and more precise it works, the more accurately the watch measures time. Likewise, it is well known that when designing a balance, the largest mass must be on the outside of the hoop.

The Maybach watches have an ETA movement which is refined by removing the balance and replacing it with a Glucydur. Balance - the heart of a watch Even before the invention of the material Glucydur and the construction of a Glucydur balance, it was clear to every watch connoisseur: The heart of a mechanical watch is the system around the balance. The better and more precise it works, the more accurately the watch measures time. It is also well known that when designing a balance wheel, the largest mass must be on the outside of the hoop.
In parallel with the development of the Nivarox hairspring material, Swiss scientists were working on the matching balance wheel in the 1930s. A new type of material called Glucydur presented itself for this purpose. The word is composed of the French words glucinium (beryllium) and dur (hard). This material is a copper alloy. Berrydur, as the material is also called, is created by the addition of about three percent beryllium. The distinguishing feature of these balance springs is their golden color.
A Glucydur balance has a hardness of 380 Vickers compared to 220 Vickers of a nickel balance and 180 of a brass balance. This makes them excellent for riveting, balancing and equally fine adjustment. Robert Lavest, ex-director of the Le Locle watchmaking school, described the Glucydur balance as follows: "This balance, made of a very hard metal, hardness 400 Brinell, amagnetic, non-oxidizing, with a fine shine, is distinguished by its remarkable finish and the dignity of fine craftsmanship which it gives to a movement. For mass-produced products as well as for special movements, the Glucydur balance is much sought after, appreciated by pivot-rollers and also by regulators. The Glucydur balance facilitates regulation and its invention represents an important step in watchmaking technology.
