SIHH 2012: IWC Top Gun Miramar
The Top Gun Miramar Chronograph> is powered by the new in-house caliber 89365, as opposed to the Valjoux/ETA 7750 which previously powered the older version. This is a significant upgrade. The new caliber features a flyback function, a massive 68-hour power reserve and IWC claims, "it is one of the most advanced and robust chronographs ever produced."
The 46 mm diameter case is made of grey ceramic (zirconium oxide), with a polished finish. The dial is a matte anthracite color that is contrasted by camouflage colored beige hands and chapter ring, along with a green textile strap. Titanium case back, pushers, crown and buckle complete the look. (Ref. IW388002)
