This 1970s vintage chronograph is the popular "Orange Boy" version of the automatic Heuer Autavia 1163. It has a stunning tropical dial.
Tropical dials are the result of a rare phenomenon in vintage watches, where the color of the dial changes over time due to various environmental factors such as sunlight, humidity and temperature fluctuations. This aging process, usually in combination with a lacquer defect, can cause the dial to lose its original color and take on a brownish hue. Tropical dials are particularly coveted by collectors because they give the watch a charismatic vintage character and uniqueness.
The formerly black dial of this Autavia developed an absolutely uniform brownish color over the years. Due to the orange accents in the hands and indexes, this model is also known as the "Orange Boy". This color combination is very popular with collectors and, together with the tropical patina, gives the watch a stunning vintage look.
This Autavia is equipped with the automatic Caliber 12, that operates perfectly. It is the improved successor to the legendary caliber 11.
