The P.2003/10 movement is an automatic movement with an impressive blend of technology and art, of form and content. The technology is revealed in the top-end characteristics of the calibre: with a diameter of 13¾ lignes (31 mm) and three spring barrels which give the watch a power reserve of ten days, the movement has 25 jewels and a balance which makes 28,800 vibrations per hour (4 Hz). The main functions are hours, minutes, small seconds, date and linear indication of the remaining power reserve at 6 o’clock while a central arrow hand enables the time in a second time zone to be read, with the relative AM/PM indication on the counter at 9 o’clock. The artistic aspect consists of the delicately worked skeletonising, which reveals the complexity and sophistication of the movement. At first glance it is the rotor of the oscillating weight which catches the eye, grooved and with highly finished engraving embellishing the inscription “Officine Panerai” on the outer edge. Such a high standard of finish is the mark of top class calibres and demonstrates the abilities and skills of the Officine Panerai Manufacture.
