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.

Originally designed and manufactured in Grenchen, Switzerland we’ve kept true to our roots. Our Chronomaster is powered by the Swiss-made Sellita SW510 Chronograph with a choice of either the manual or automatic wind version. All of our watches are made in Switzerland in true Nivada Grenchen authenticity and quality standards.
Nivada Grenchen rose to fame in the 50's & 60's for their ruggedness by always pushing the limits of watch design. The Chronomaster is no exception to this rule - featuring a 10ATM water resistance & a curved sapphire crystal it is ready to face the usual wear & tear of everyday use.
