Panerai Luminor due 3 days automatic acciaio 45mm PAM00674. The new Luminor Due 3 Days Automatic is the first watch in the LUMINOR DUE collection with automatic winding and it contains one of the most sophisticated movements made by the Panerai Manufacture in Neuchâtel, the P.4000 caliber with decentralized micro-rotor. Compared to the similar Luminor 1950 models already in the collection, the ingenious structure of this caliber 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. Immediately recognizable by the iconic bridge device protecting the winding crown, the case is available in AISI 316L stainless steel. 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. The new Luminor Due 3 Days Automatic has the P.4000 caliber. the thinnest automatic caliber developed by the Panerai Manufacture. The most distinctive feature of this caliber is the decentralized micro-rotor 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 synchronizing the time perfectly. The Luminor Due 3 Days Automatic is supplied with a black alligator strap. It is water-resistant to 3 bar (about 30 meters).
