The Chronomaster Aviator Sea Diver (CASD for short) is far from your typical chronograph. Originally designed in 1963, it was intended to be a tough diving capable chronograph that could be used in any situation. Its iconic dial-bezel combo packs as many complications as was known to be possible in the 60's. From the standard stop-watch function to a tachometer & a yachting timer, the Chronomaster is in short, for versatile men in need of a versatile timepiece.
