The white enamel porcelain dial is one of the most striking elements of this watch. Surrounding it are elegant Roman numerals for the hours and a minute scale with black Arabic numerals. Hand-applied gold ornaments emphasize its decorative character. The sub-dials indicating the month, day of the week, and date are in French, a typical feature of Swiss watchmaking of the period. The hands, black and finely crafted in the Louis XV style, perfectly complement the overall design.

On the sides of the case, there are small pushers that allow adjustment of the various calendar functions, a typical technical solution of complicated watches from the late 19th century. The visible movement reveals meticulous work of gears and components made of bronze and steel, the result of Swiss haute horlogerie craftsmanship.


Pocket watches with complications such as the complete calendar and lunar phases appeared in the 18th century but reached their peak in the 19th century. The combination of these functions represented the ultimate mastery of mechanical watchmaking, which aimed not only to tell time accurately but also to record it astronomically and calendrically. The indication of lunar phases had both a romantic and scientific aspect, allowing the lunar cycle to be tracked with a precision appreciated both in rural areas and among astronomy enthusiasts.

In the 19th century, Switzerland established itself as the undisputed leader in the manufacture of watches with big complications. Major watchmaking houses developed increasingly complex and reliable mechanisms capable of displaying the days of the week, months, date, and moon phases on small dials integrated into the main dial. These pieces were almost entirely handcrafted, intended for a select clientele who appreciated both practical utility and technical and aesthetic refinement.

This type of watch, with its multiple functions adjustable by external pushers, required great technical skill both for its manufacture and maintenance. It is not surprising that many of these watches are now found in museums or private collections. Over time, pocket watches gradually replaced wristwatches, especially after the First World War. However, vintage models with complications remain highly sought after today for their beauty, rarity, and the testimony they offer of a golden age of artisanal watchmaking.
