Object description

Case and Dial Construction

The timepiece is housed in a three-body, polished stainless steel case with a cushion-shaped profile. The architecture of the case is defined by fixed wire lugs which are fastened to the main body via four screws, a traditional element associated with the Radiomir line. The case features a screwed-down winding crown, enhancing the water resistance to a stated depth of 100 meters. The back of the case is also screwed down and incorporates a transparent window.

The dial is rendered in black and is applied with luminous baton indexes, alongside prominent Arabic numerals at the 6 and 12 positions. The visual arrangement includes subsidiary dials for constant seconds and a 30-minute chronograph register. An outer tachometer graduation is present on the periphery, complemented by minute and seconds divisions. The hands are fashioned as luminous steel batons, ensuring legibility under various conditions.

Movement and Technical Specifications

Precision in timekeeping is managed by a monometallic balance equipped with a shock absorber system and a self-compensating flat balance spring. The integration of the chronograph function is achieved via round buttons situated on the case flank.
