The Guinand watchmaking family is synonymous with Swiss chronometers and tourbillons of the highest quality. Many watches of this kind were intended for export to South America or, as is the case with the item presented here, to Cuba and were delivered with the typical champlevé dials, also used for this item.

Guinand
B. Guinand generally refers to the work of the Guinand family, a lineage of master watchmakers from the Swiss Jura region (specifically Les Brenets and Le Locle) who specialised in high precision pocket watches and chronographs during the 19^th and early 20^th centuries.

While the family name is most famously associated with the brand Guinand Frères, individual members like Benoit Guinand or his relatives often marked movements or cases with their initials.
