The challenge of a long power reserve, which enables the watch to run uninterruptedly for more than a week without requiring any manual intervention, was tackled by Panerai at the beginning of the 1940s with the usage of a hand-wound Angelus® movement with eight days of power reserve, a very solid, reliable calibre. These characteristics were vital for the Panerai watches used by the underwater commandos of the Royal Italian Navy, which had to be reliable even in the most extreme conditions of use. The long power reserve significantly reduced the manipulations on the winding crown, which improved the durability and helped to maintain water-resistance. Thus it became one of the distinctive elements of the Panerai watches and a part of the DNA of the Brand. It is indeed no coincidence that the first movement (P.2002) developed by the Panerai Manufacture in Neuchâtel in 2005 was a calibre with a power reserve of eight days.
3-DAY POWER RESERVE
RADIOMIR 1940 3 DAYS
GMT AUTOMATIC ACCIAIO – 45 MM
PAM00657
MOVEMENT Automatic mechanical, P.4001 calibre, executed entirely by Panerai. FUNCTIONS Hours, minutes, small seconds, date, second time zone, 24h indicator, power reserve 3 days, seconds reset. CASE 45 mm, AISI 316L polished steel. DIAL Black with “vertical stripes”, luminous Arabic numerals and hour markers. Date at 3 o’clock, seconds and 24h indicator at 9 o’clock. WATER RESISTANCE 10 bar ( ~100 metres).
THE CALIBRE P.4001
The P.4001 is developed from the automatic P.4000 movement: the off-centred micro-rotor which rotates in both directions, the power reserve of three days stored in two spring barrels linked in series, the mechanism for stopping the balance, enabling the time to be set with absolute precision and the full balance bridge with twin supports for greater stability.
The new calibres also have some extremely useful additional functions: the date, the GMT function with a central hand which indicates the time in a second time zone, am/pm indication (relative to home time) in the small seconds dial and, finally, indication of the remaining power reserve.
The P.4001 has the circular indicator on a bridge of the movement. Finally, two very useful devices make setting the watch extremely simply and precise: the first is the mechanism which stops the balance and zeroes the seconds hand as soon as the winding crown is pulled out; the second enables the local time hand to be adjusted forward and backward in jumps of one hour at a time, without stopping the minute hand or interfering with the running of the watch, but automatically adjusting the date.

THE CALIBRE P.4002
The P.4002 calibre shares the same characteristics of the P.4001 calibre: the off-centred micro-rotor which rotates in both directions, the power reserve of three days stored in two spring barrels linked in series, the mechanism for stopping the balance, enabling the time to be set with absolute precision and the full balance bridge with twin supports for greater stability.
The new calibres also have some extremely useful additional functions: the date, the GMT function with a central hand which indicates the time in a second time zone, am/pm indication (relative to home time) in the small seconds dial and, finally, indication of the remaining power reserve.
The P.4002 has the indicator positioned directly on the dial at 5 o’clock. Finally, two very useful devices make setting the watch extremely simply and precise: the first is the mechanism which stops the balance and zeroes the seconds hand as soon as the winding crown is pulled out; the second enables the local time hand to be adjusted forward and backward in jumps of one hour at a time, without stopping the minute hand or interfering with the running of the watch, but automatically adjusting the date.

Date at 3 o’clock, seconds and 24h indicator at 9 o’clock, linear power reserve indicator at 6 o’clock. WATER RESISTANCE 5 bar ( ~50 metres).
THE CALIBRE P.2002
The P.2002 hand-wound calibre is the progenitor of the P.2000 series and it takes its name from the year in which the project was launched to supply Panerai watches with movements entirely designed and developed at the Manufacture in Neuchâtel. The P.2002 calibre consists of 247 components; it has 21 jewels and a thickness of 6.6 millimetres. Hand-wound and with a power reserve of 8 days with linear indicator on the dial, it has the characteristics peculiar to all the calibres of the P.2000 series: great structural strength; three spring barrels; GMT function with 24-hour indicator; seconds reset device; rapid adjustment of local time; free-sprung balance; balance wheel oscillating at 28,800 alternations per hour (a frequency which is unusual in a movement with a large power reserve). The three spring barrels in series, the design of which is an Officine Panerai patent.

WATER RESISTANCE 10 bar (~100 metres).
THE CALIBRE P.2003
The P.2003 was the first automatic movement entirely designed and created by the Panerai Manufacture in Neuchâtel. It is an automatic calibre of advanced technical content with an unusually long power reserve of 10 days (240 hours).
As in the case of the P.2002, such a prolonged power reserve is possible because of the innovative system (patent filed) with its unusual energy accumulator, consisting of three spring barrels: two of these are located one above the other, while the third is linked through a gear train which enables the power remaining to be indicated on an appropriate graduated scale.

THE CALIBRE P.2004
The P.2004 calibre is the first chronograph movement created entirely by the Panerai Manufacture, an expression of the quality of mechanical tradition applied to sports watches. The calibre P.2004 is a hand-wound mechanical movement with a power reserve of 8 days.
It is a single-button column wheel chronograph which combines the start/stop/reset functions in a single push-piece. This push-piece is positioned at 8 o’clock so as to maintain the unmistakable appearance of Luminor watches, with the device protecting the winding crown, a distinctive feature of the design of Luminor cases.
