Radiomir 1940 Equation of Time 8 Days Acciaio

The Radiomir 1940 Equation of Time 8 Days Acciaio creates a connection between solar time and the mean local time. Supplemented by the date, month display and the small seconds this model allows a fascinating comparison of the actual time with the usual concept of time. A variant of the P.2002 calibre with a very long power reserve and display back drives the rare complication of the so-called equation of time.

For everyday practical reasons, the day was divided into 24 hours. However, this division is only an average and deviates from the true solar time by a maximum of around 15 minutes due to the Earth's elliptical orbit and the tilt of Earth's axis. With the PAM 516, OFFICINE PANERAI presents a special edition that shows the correct values.

"Equation of Time" - the precise course of time

Since about 200 years ago, the image of the equation of time has been shown on the dials of the most impressive complications in watchmaking and this has eliminated the need of tables and charts for its exact determination. In a particularly easy-to-read version, the time difference is displayed on the dial of the PAM00516, which has the distinctive feature of showing its linear progression. This makes it possible to read the value at a glance and to determine the true solar time.

The classic aesthetics of the 1940 Radiomir

The PAM 516 is inspired by the 1940’s Radiomir, with its elegant lines and a timeless elegance. At 48mm in diameter, the stainless steel housing allows a large-format dial, which in turn enhances the visibility. In the PANERAI the dial is formed in a sandwich construction and is designed simply and clearly. The small second is at the 9 o’clock position. This display is opposite the date which, in combination with a month display in circular form, shows each day of the year exactly, the equation of time is shown at 6 o’clock. The hands and the markers are created out of a sand-coloured, fluorescent substance so that they shine in low light, in this way the PAM 516 remains faithful to the 1940 Radiomir.

In fact it’s a technical masterpiece

The manually wound calibre P.2002/E reaches a remarkable power reserve of eight days, which became important in the brand's history in the 1940’s. A power reserve indicator has been omitted from the matt-black dial. Instead the remaining power reserve can be read from the back through the sapphire crystal case-back. The sapphire crystal offers a clear view of the balance, which performs at a stable frequency of 28,800 vibrations/hour during the entire running time.
