IWC – Spitfire Perpetual Calendar Digital Date-Month

IWC - Spitfire Perpetual Calendar Digital Date-Month

For the first time, the Spitfire Perpetual Calendar (IW379105) watch with a large digital date and month display was presented in 2012. It was offered in the precious 18K red gold case, so the price was quite huge.

This time, the new edition of the Spitfire Perpetual watch is in more friendly and attractive price, because of its case made of an affordable stainless steel. It is really cool information for the IWC fans and aviation enthusiasts, but not only.

The new, stainless steel Spitfire watch includes everything, what builds a real Pilot’s watch. Big, stylish crown, massive and legible dial with numerals easy-to-read. It also bears characteristic for the aviation design codes like the large digital date and month display stylized for the instrument called the altimeter, which shows the altitude of the object above a fixed level.

This watch has been design with the incredible taste and sense of the harmony and proportions. Its big numerals and every dial’s feature don’t seem to be too overwhelming at all, it is perfectly designed. Pretty massive case with a diameter of 46mm hides the same in-house 89801 calibre mechanical movement with a self-winding. It features the 68-hour of power reserve, when fully wound.

Beautifully polished bezel and satin-finished case make a slight contrast to the dial in the ardoise colour. The hour markers and hands come with the luminescent coating to provide clear read both in the light and a dark conditions.

Spitfire Perpetual Calendar watch is equipped with the complications like the Perpetual Calendar displayed digitally in large numerals at 9 o’clock (Date) and 3 o’clock (Month). Small seconds are presented at 6 o’clock in the sub-dial along with the 4-year leap year cycle. The bigger sub-dial situated at 12 o’clock includes hour and minute indicators together in a single counter. Besides these functions, we get also the stopwatch function with hours, minutes and seconds, which can be easily reset thanks to the flyback function.
