Description
This Heuer Calculator 110.633 from the 1970s impresses with its unpolished case and its excellent overall condition.

The Calculator Chronograph was designed by Heuer for scientists. Mathematical arithmetic operations can be read off with the help of the rotating bezel. An original instruction manual, which can also be found online, explains how the slide rule bezel works.

The present example is in excellent condition. Although the case shows few natural signs of wear, it is unpolished and has very sharp edges, a condition that every discerning vintage collector is searching for.

The deep blue dial with orange hands is immaculately preserved. The chronograph has a 30-minute counter with orange stripes, a 12-hour totalizer and a date display. The tritium is original and has never been repainted. The Heuer automatic caliber 12 still ensures precise timekeeping and the flawless operation of the chronograph.

Another highlight of this watch is the original stainless steel bracelet from the 1970s with the Heuer Logo on the buckle. These bracelets are very rare and sought after.

The Calculator Chronograph is one of the most remarkable models from the renowned manufacturer and this excellently preserved example is a wonderful addition to any vintage collection.
