Hamilton Khaki X-Mach Watch

Stay stylish while confusing onlookers with the Hamilton Khaki X-Mach Watch ($1,125). Not content to simply tell time, or offer a chronograph function, the X-Mach does exactly what the name suggests, letting you measure the Mach speed of an aircraft. In addition, it features a stunningly complex black dial with day and date calendar, a black PVD steel case, and a black leather strap with a crocodile pattern and carbon fiber inlay. If anyone should ask why the hell you need such a complicated wristwatch, simply reply, "I'm a pilot."
