The P.4000/10 calibre is the fascinating, precious, skeletonised version of the P.4000 calibre, the thinnest automatic calibre developed by the Panerai Manufacture. The most distinctive feature of this calibre is the decentralised micro-rotor in 22-carat gold oscillating weight having Clous de Paris decoration which rotates in both directions, feeding energy into the two spring barrels which accumulate a power reserve of three days. The balance bridge is the type with twin supports, more secure and stronger than the single cantilever balance cock, and the watch also has the device which stops the balance wheel when the winding crown is pulled out, for synchronising the time perfectly. The bridges have circular brushed finish and gilded engraving, and they are skeletonised to allow a large part of the movement to be seen, every detail being clearly visible through the large porthole in sapphire glass which opens on the back of the case.
3 Days Automatic Oro Rosso - 45 mm
The red gold model of the Luminor Due 3 Days Automatic has the precious, skeletonised P.4000/10 calibre, the thinnest automatic calibre developed by the Panerai Manufacture. Its 22-carat gold oscillating weight having Clous de Paris decoration. The ingenious structure of this calibre and the work of the designers has enabled the thickness of the case to be reduced by about 40% (10.7 mm), while maintaining the solidity, strength and functionality of the watch and leaving its distinctive design unchanged. The design of the dial, with its sandwich structure, is minimalist, in perfect Panerai style: figures at the cardinal points, bar markers corresponding to the hours and an auxiliary small seconds dial at 9 o’clock.
