Slim watches have paradoxically always provided watchmakers with the best means of lending substance to their talent, while also enabling their owners to reveal a noble-minded and impeccably well-cultured approach. Baume & Mercier has made a number of thin watches in the course of its history. First launched in 1965, the ultra-thin white gold watch, powered by a self-winding micro-rotor movement, still offers one of the finest examples of this passion. Representing the ultimate balanced classical watch, this model belonging to the Baume & Mercier museum inspired the Classima collection and has shaped its success. The Classima collection is inspired by a slender watch from the late 1960s. The extremely pure case combining straight lugs with a guilloché silver-colored dial is unanimously appreciated by connoisseurs for whom minimalism and finesse are a token of durability. Further heightening this impression of purity, Roman numerals and slim indexes share the available space in a supremely discreet manner. This timepiece fitted with an alligator strap or steel bracelet is driven by a mechanical self-winding movement. It is an instrument designed to meet the expectations of those keen to wear a model perfectly tailored to match a strict and chic business suit.
