The P.3001 is a hand-wound caliber designed and produced in-house by Panerai Manufacture in Neuchâtel. Fully developed and manufactured in-house, the caliber is not only very durable, but also extremely accurate. Actually, these Swiss movements are some of the most accurate and best performing on the time pieces market, representing a clear indicator of the quality craftsmanship that is a trademark of the manufacturing company Panerai.
Taking after a previous caliber movement – the Angelus – the P.3001 has a size of 16 1/2 lignes, and suited in a large case. The size of the movement is not without a reason: it helps with technical features that are highly appreciated by users such as accuracy and durability. A bolder size also means better visibility. The P. 3001 presents several features that are similar to the Angelus caliber 240. One of them refers to the going train placed beneath a single bridge, while the mainspring and winding mechanism are covered by a second bridge. There are, however, some differences, too. For instance, the P.3001 replaces the balance cock with a sturdy balance bridge, and features a power reserve indication that can be located on the barrel bridge.
The two main watch models to have featured the P.3001 movement until present day is the Luminor Marina 1950 3 Days Acciaio (PAM00422) and the Radiomir 3 Days GMT Oro Rosso (PAM00421).
A throwback to some of the iconic pieces created by Panerai, the P.3001 features the hallmarks of a classic Panerai watch with all the appealing characteristics of a modern piece, being robust and achieving the highest time measuring precision.
Being hand-wound and rather large in size, the P.3001 truly feels like a vintage pocket watch, and epitomizes the class and sophistication such a device can offer. It has only two hands – one for hours and for minutes, along with a smaller hand for seconds. There is no date aperture feature, providing a simple yet sophisticated watch movement when used with a PAM422.
Using the P.3001 with the PAM421 results in the watch having additional features, most notable a date function and GMT functioning as well. A power reserve indicator can be found at the back case of the movement. When the caliber P.3001 is used for the PAM421, a date and GMT function will also be present.
The second hand can also be automatically reset back to zero, which is an appealing functionality for all those who enjoy perfect synchronization of the time. Combined with the ability to move the hour hand entirely separately from the minute hand, the P.3001 provides complete control of time setting, which is useful for those who travel throughout different time zones.
Think of this caliber as the perfect everyday piece. It is highly durable and very reliable thanks to its impressive shock absorbers, showcasing its ability to withstand the trials and tribulations of everyday life. Be it commuting to work or going for a casual stroll, the P.3001 is designed to handle anything you might throw at it. No need to remember to take your watch off when going to the gym or undergoing various harsh circumstances that might damage a valuable time piece.
The movement measures in at 16 ½ and is 6.3mm thick, another example of the larger size of this piece which highlights the aesthetic appeal of its vintage design. It contains 21 jewels, with two spring barrels that are connect in series. It is made up of a total of 207 components, and features a Glucydur balance and Incablock anti-shock device. The 21,600 alterations per hour equate to roughly 3 Hz.
