Officine Panerai’s special editions for 2015 choose to tackle one of the most interesting astronomical complications, “the equation of time”. For those who aren’t familiar with the concept; basically the difference between “mean” time indicated by a watch and “true” time indicated by the solar meridian is called ”equation of time”. So, the length of one day is derived from the period of one rotation of the Earth and the length of one year is related to the period of one revolution of the earth around the sun. As the saying goes: ”Science is enforced humility”. Because the truth of the matter is that a day only measures exactly 24 hours on four occasions per years, while on all other days, apparent time (solar time) and conventional time (mean time) tend to vary up to 15 minutes before or ahead, depending on the time of year.
This Panerai model: “Radiomir 1940 Equation of Time 8 Days Acciaio”, uses a linear indicator on the dial to try and tell “real time/solar time” vs “apparent time”. In order for the watch to be able to tell the difference it has to have the right month and date set on it. The movement that powers this timepiece is based on a variation of Panerai’s first in-house manufactured movement (P.2002), the new P.2002/E movement. It’s made up of 328 parts, with beats at 28,000bph and three spring barrels that give this watch a power reserve of 192h, to sum up 8 days.
It bears Panerai’s signature sandwich-style dial, with gold hands and a tan luminous glow which gives off a vintage feel. The date window is at 3 o’clock with a circular indicator for the months and at 9 o’clock are the running seconds with a reset function. The equation of time indicator is displayed using a horizontal meter at 6 o’clock. The “Radiomir 1940” also has a sapphire display caseback where the power reserve can be read on the back of the movement.

This watch model comes in a 48mm polished steel case and bezel. It has a screw-down crown and has been rated water-resistant up to 100m (330ft). “Acciaio” is the Italian word for steel. And to claim it’s been made in a 1940’s style; means it doesn’t feature the wire lugs of the regular Radiomir models. Hence the name: “Radiomir 1940 Equation of Time 8 Days Acciaio”. This model will be limited to 200 pieces.
Overall Panerai has managed to fit a lot of features on the dial while maintaining a smooth and elegant look. The circular indication of the month was a nice feature, but may be an intrusion during the month of March, because the hand will be blocking the day-date during the whole month of March; let’s just call it an oversight, or March madness.
