ETA Movement in refinement

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. The movement is decorated and polished, a process known as Côte de Genéve finishing!

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.
