The Radiomir Firenze is entirely hand-engraved by Italian master craftsmen, making each timepiece unique. Its design is inspired by motifs existing in the Florentine iconography. Similar to the inlays adorning the marble facades of the Florentine's churches, the engravings enhance the elegant structure of the case, enfolding the case-band and the crown. Shaped by the master craftsmen, the lines appear to form geometric figures creating a harmonious piece. Some symbolic details stand out, such as the Florentine lily, emblem of Firenze.
The engraving is entirely done by hand, and each case takes one craftsman more than a week to finish. The geometric and floral motifs are first drawn as a temporary outline – using powdered chalk or magnesium powder – and then engraved with a burin. The engraved surfaces are formed of very thin parallel lines, giving depth to the design and accentuating the contrasts between light and dark.
The new Radiomir Firenze houses a hand-wound mechanical, P.3000 calibre, executed entirely by Panerai and visible through the sapphire case-back. Two mainspring barrels, connected in series, provide 3 days of power and the balance wheel oscillates at a rate of 21,600 vibrations per hour. The P.3000 movement is equipped with a system that allows the adjustment of the hour, through the decorated crown, without interfering with the running minutes or the timekeeping of the movement. Consistent with its origins as a watch originally designed for military use underwater, the new Radiomir Firenze (PAM00604) is water-resistant to 100 metres. It is supplied with a black alligator strap.
The Panerai Radiomir Firenze is limited to 99 pieces and is only sold at the Florence boutique in Italy.
