As watches continue to embrace a wider range of color options for their dial, straps, and other details, orange remains relatively scarce in the expanding spectrum, though undeniably appealing to a core of loyal fans. Here are five timepieces where orange tones dominate.   

HUBLOT BIG BANG TOURBILLON AUTOMATIC ORANGE SAPPHIRE

Hublot takes pride in being the first watch manufacturer to make sapphire cases on an industrialized scale and even greater pride in its leading role in creating new color variations in that difficult-to-machine material ? most recently, orange. The translucent 45-mm case of the Big Bang Tourbillon Automatic Orange Sapphire is achieved through a process that incorporates titanium and chromium. It attaches to a matching orange, structured rubber strap with a lined relief pattern, equipped with Hublot?s patented One Click interchangeability system. Inside the world?s-first case is a world?s-first movement, Hublot?s Caliber MHUB6035, a skeletonized, self-winding tourbillon movement that amasses its three days of running autonomy by means of a 22k gold micro-rotor placed unconventionally at 12 o?clock on the dial side. Price: $169,000, limited to 50 pieces.
