IWC Schaffhausen Big Pilot’s Watch Big Date Edition 150 Years

As part of the celebrations for the brand’s 150th anniversary, IWC have done something rather unusual. They have given the classic pilots watch a big date display. Pilots watch purists probably won’t like this. A pilot’s watch should have just hour and minute hands, a central second-hand, Arabic numerals and virtually nothing else on the dial. In this piece, there is a small seconds display at 6 o’clock and the big date display at the top of the dial.

Enamel dial

If you like large watches, you’ll love this watch. It is 46.2 mm in diameter and 15.2 mm thick, with a stainless steel case beautifully finished in differentiated polished and brushed surfaces. it has a large conical screw-in crown – in a shape typical of pilot’s watches – and a water resistance of 6 bar, 60 m. The numerals and hands are coated in SuperLuminova and they contrast well with the blue enamel dial.

Solid caseback

When you turn the watch over you see the solid case back with just a window showing the power reserve. Like classical pilot’s watches, this piece has a soft iron inner case to provide protection against magnetic fields and so there would be no point in having a sapphire caseback. In a way this is a pity because the hand-wound calibre 59235, based on the existing 59210, is a lovely piece of watchmaking, large and beautifully finished.

8-day power reserve indicator

On the calibre 59210 the power reserve is on the dial side. For the Big Pilot’s Watch Big Date the movement was adapted by moving the power reserve to the caseback side and adding the big date function based on two concentric numeral discs.The size of the movement makes it possible to have a very large mainspring barrel, and the watch, which is hand-wound, has a power reserve of 192 hours, 8 days, so that winding becomes a weekly ritual. It would be capable of running for even longer, as it incorporates IWC’s stopping device that brings the movement to a halt once the mainspring has reached a certain minimum torque. This ensures that precision is optimal throughout the entire eight-day period. The balance runs at 28,800 vibrations per hour (4 Hertz) and has 30 jewels.
