1970s Aquastar Benthos 500 Chronograph (Ref. 1002) "Minute Creeper"

The Aquastar brand is "relatively" new to the watchmaking world as they didn't debut as a company until 1962 in Geneva and were most known for their watersport-related timepieces, such as diving watches and regatta chronographs. Included in that list is the now-famous Aquastar Benthos 500, the world's first-ever watch rated to 500 meters.

Featuring a remarkable A. Schild cal. 2162 movement, the Aquastar Benthos 500 ref. 1002 is what is known to the horological community as a "minute creeper" or "slow counter". The minute creeper's chronograph hand advances by the minute, instead of by the second, resulting in a much slower revolution of the center chronograph hand. That being said, this chronograph tracks time in an extremely legible way. Indicated by a large, luminous, bright orange hand. A notable feature of the A. Schild cal. 2162 is that the minute counter chronograph is always running, and is reset to 0 by using the reset pusher located at the 4 o'clock position on the case.
