The main novelty of the Radiomir Tourbillon GMT Ceramica – 48 mm is its refined skeleton structure, clearly visible from the dial. This in fact, is made of a fine mesh that supports both a fine external band, with small ecru-coloured luminescent Arabic numerals and hour markers and also the subsidiary dials, showing the small seconds, tourbillon movement and am/pm. The second time zone is indicated by a third central hand, which finishes in an arrow point, as luminescent as the hour and minute hands. The shape of the dial allows the numerous parts of the movement to be seen, including the tourbillon regulator at 10-11 o’clock. The dial is protected by sapphire crystal made from corundum (1.9 mm thick), with double anti- reflective coating.
The 48 mm diameter case is made of a zirconium oxide ceramic, an exceptionally hard, corrosion- resistant material that is first pressed in a single block and then fine-milled to give it, after numerous operations, its final cushion shape. The back-plate, made from a ring of titanium, houses a large window in sapphire crystal through which the movement can be seen.Despite the technical complexity of the tourbillon movement and the special material used for the case, this watch is waterproof to 10 bar (about 100 metres), thus qualifying as a true traditional Radiomir.
The new Radiomir has a P.2005/S movement with a diameter of 16 1⁄4 lignes and 31 rubies, characterised by its tourbillon that rotates perpendicularly to the axis of the balance, completing two rotations a minute instead of one and thus guaranteeing greater precision. Comprising 277 parts, the movement is the result of exceptional work by the maestro watch-makers at Officine Panerai and, thanks to its three spring barrels, enables a power reserve of six days, indicated by a hand that can be seen through the back plate moving through the arc of a circle. With reference PAM00348, the Radiomir Tourbillon GMT Ceramica – 48 mm has been produced in only 30 units, all millemised and numbered. It comes on a leather strap with adjustable buckle in scratch- resistant burnished steel.
