Aquastar Regate for Heuer Ref. 4000N

Aquastar was founded in 1962 and focused on watches intended to be used around water. In 1964 the company collaborated with Heuer on the Regate. Aquastar produced the watch and Heuer distributed it. This was an early collaboration before collabs became a thing. The function of this watch, aside from keeping time, is a 5 minute count down timer. This function was specifically meant for timing the start of a yacht race. This particular watch is in excellent unpolished condition. The case is super strong with very few surface scratches. All the writing and hallmarks on the case back are strong and clearly visible. The all original silver dial is pristine with neat hour markers. This lovely watch is powered by a Felsa 4000N automatic movement.
