The P.9003 automatic calibre is one of the latest lines produced by Panerai. The model was first released in the year 2014. It was specifically created for use with the Panerai Luminor 1950 3 Days GMT 24H and its technical specifications suit this watch model’s design. The calibre itself was originally developed around the P.9001 and comes with quite a few notable features that set it apart from this original design concept.
The first and most prominent of these is the GMT 24 hour function, as well as the second time zone indicator, which is on the outermost edge of the dial and featured automatic in-house movement. This GMT function allows for time to be indicated over the 24 hour time rather than the traditional 12 hours. This feature is rather interesting as most luxury watches have a 12 hours dial approach.
The Panerai Luminor 1950 3 Days GMT 24H featuring a P.9003 calibre can therefore be used by wearers to help determine the time of a different time zone from the one they are currently in, a perfect addition for the traveling watch wearer. The independent hand that displays this time is the large hand that features a large arrow design. This dial will make one single rotation during 24 hours.
Another feature is that of the power reserve indicator on the back, which has been designed in a circular fashion and allows for a clear view of the indicator. This is protected by the transparent sapphire crystal of the case back, and measures at 2.6mm thick.
When it comes to the power reserve specifications, the P.9003 calibre movement features a reserve that can last up to three days, which is accomplished by connecting two spring barrels in series. This comes to underline values like robustness and durability the brand stands for.
The dial features an interesting black colour and nicely designed Arabic numerals along with hour markers, both of which are luminous – this provides a clear view of the dials even when the lighting conditions are not the greatest. The date function is situated at 3 o’clock and connected to the hour hand of the watch, with seconds being indicated at 9 o’clock. There is also a device that allows for seconds to be reset, allowing for a perfect synchronising when used with a reference time signal.
When regulating the time, the hour hand is able to be moved entirely on its own as well as increments of one single hour. This allows for adjustments to be made that do not interfere with either of the minute or seconds hands. This way, you will be able to make small adjustments, if needed, in no time.
The automatic mechanical P.9003 calibre features a diameter that is 13 ¾ lignes and its thickness measures to 7.9mm. With 28 jewels present in the movement, it is built using a total of 233 components.
With the balance wheel oscillating on a frequency that is 4Hz, the alternations per hour clocks in at 28,000. There is also an Incablor® anti-shock device present, along with Glucydur® balance. These features are meant to provide the movement with a high level of resistance to various external factors so that it can be used within the most unfavourable circumstances. The watch is also water resistant to 30 bars (300m), so it can be worn while taking a swim, but it does not make the appropriate accessory for a deep sea dive.
