Object description

Case and Dial

The watch is housed in a rectangular case constructed from white gold, featuring a distinct triple-step edge geometry that creates a structured profile. The case dimensions are recorded as 33 by 41 millimeters. The design focuses on the material quality of the dial, which is composed of a solid piece of black onyx stone.

In accordance with the minimalist aesthetic, the dial is devoid of hour markers or indices, displaying only the brand name at the top center and the word 'SWISS' at the lower edge. The central hands are fashioned from white gold and lack luminous material, maintaining a clean appearance that emphasizes the natural texture of the onyx.

Movement and Functionality

This timepiece is equipped with the Beta 21 caliber, an early electronic quartz movement produced in Switzerland during the late 1960s. The development of this movement was a collaborative effort initiated by the Centre Electronique Horloger (CEH) to introduce quartz technology to the Swiss market.

Approximately 6,000 units of the Beta 21 were manufactured, finding use in luxury models from brands including Rolex, Patek Philippe, and Omega, alongside Piaget.
