Ahead of SIHH 2012 later this month comes a look at the IWC Top Gun Miramar Chronograph, the latest edition to the Swiss watchmaker’s Pilot Collection. The beauty is powered by the new in-house caliber 89365 movement as opposed to the Valjoux 7750 which was found in the past versions. The new caliber is more advanced and robust than its predecessor as it features a flyback function and a 168-hour power reserve. The design is military-inspired with a case that’s made from scratch-proof grey ceramic. The dial’s a matte anthracite color with camo-colored beige hands and chapter ring and a green textile strap to finish things off. More details to drop once this beauty is unveiled at SIHH along with four other models from the Pilot collection.
