The Louis Erard x Alain Silberstein Smile-Day Blue & Tourbillon Régulateur Blue

Louis Erard has spent recent years defining a very specific place for itself within contemporary Swiss watchmaking. Its strength lies in clarity of design and advanced mechanics. That balance has become central to Louis Erard’s identity.

That design awareness is especially visible in the brand’s collaborative work, where Louis Erard has shown a rare ability to absorb the language of an outside creative without losing its own. One of its most notable collaborations is with French designer Alain Silberstein, who has, over the years, developed a visual vocabulary that is instantly recognisable, one in which hands, markers, and displays become a composition of shapes as much as instruments of timekeeping.

Caliber

Caliber

Caliber, is a term that describes the engine of a mechanical watch, through a reference number for each watch, and this number indicates the size and shape of the watch movement, and is also used to identify the origin of the watch or its maker.

Each watch manufacturer or brand typically has its own set of calibers, which may vary in terms of design, complexity, and features.

Calibers can be categorized into different types, such as manual-winding calibers that require manual winding of the crown to keep the watch running, or automatic calibers that use a rotor to automatically wind the mainspring through the movement of the wearer's wrist. There are also quartz calibers, which are powered by a battery and utilize electronic circuits to regulate timekeeping.

The caliber number or code is often assigned by the manufacturer to identify a particular movement or model. It helps watchmakers, collectors, and enthusiasts differentiate between different watch models and understand the technical specifications and features of a specific watch.
