The Heuer “Boxing” Chronograph wristwatch is one of the rarest timepieces available on the market today. The present example is one of only two known chronographs and is in exceptional overall condition. The TAG Heuer catalog from 1986 displays the reference 510.547 describing it as a watch designed for timing boxing matches. The black dial features an inner bezel graduated to 15 units with each representing one three-minute boxing round with green markers represent a one-minute rest period. Additionally, there are subsidiary dials for constant seconds, 12-hours and 24-hour time.

Accompanying the chronograph is a Heuer Ring-Master stopwatch with seven interchangeable rings used to time different events including boxing. In excellent condition the present watch makes a wonderful addition to any collection. This is a collector’s opportunity to own one of the rarest chronograph available on the market and presented in near new condition.
