====== IWC Pilot's Watch Chronograph Mechaquartz ======
The **Pilot's Watch Chronograph Mechaquartz** (**Fliegerchronograph** Ref. 3740) is a [[pilot's watch]] [[chronograph]] produced by [[IWC]] from [[1988]] through [[1992]].

===== Overview =====
The legendary [[IWC Mark XI]] aviator's watch was a "cult watch". Produced from [[1948]] until the early eighties, the Mark XI was never available to the public. Sensing an opportunity in the 1990s, IWC introduced a civilian version in [[1993]], the [[IWC Pilot's Watch Mark XII|Mark XII]]. But this was not the first civilian "flieger" from IWC. In [[1988]] the company introduced this **Pilot's Watch Chronograph Mechaquartz** model, with styling from the Mark XI and the innovative [[Mechaquartz]] movement from IWC sister company, [[Jaeger-LeCoultre]].

The "Fliegerchronograph" was quite unusual for the time, since the chronograph subdials added distraction to a dial that was designed for simplicity. For this reason, the markings are quite restrained, with no circular dial around the running seconds at 6 00, simple markings on the subdials at 3 00 and 9 00, and lume only at 3, 6, 9, and the familiar triangle at 12. The hands are simple sticks too, with a point on the end of the minutes hand. The only out of place element is the date window at 4 30, with a white background contrasting with the black dial.

The Ref. 3740 was released for sale in [[1989]] and produced through [[1992]] when it was updated as Ref. 3741. It used IWC's [[IWC 631|Cal. 631]], one of the first analog quartz chronograph movements. The case maintained the 36 mm dimensions familiar on the Mark XI, though a thicker bezel gives a smaller dial overall. It was usually made of brushed [[stainless steel]], though [[yellow gold]] versions were also available. It is 10.2 mm thick and is water resistant to 60 meters with a solid caseback etched with "IWC" and "Der Fliegerchronograph". The Fliegerchronograph was available with a leather strap or metal bracelet similar to the Mark XI.

The Mechaquartz chronograph was replaced by mechanical chronograph models, the [[IWC Pilot's Watch Doppelchronograph|Doppelchronograph]] first in [[1993]] and then the [[IWC Pilot's Watch Doppelchronograph|Pilot's Watch Chronograph, Ref. 3705]] in [[1994]].
