n 1940 Croton was formed to distribute Nivada watches to US retailers, and subsequent watches could be found bearing the name ‘Croton’, or ‘Croton Nivada’ or even ‘Croton Nivada Grenchen’. By the ‘60s, Nivada had hit their stride with watches like the Chronomaster, Aviator, Sea Diver. The unique design and functionality of these watches struck a high note with consumers, and Nivada saw their exports go from 52,000 in 1964 to 173,000 in 1969 as a result. Croton also worked with jewellry stores to promote their wares.
The Chronomaster chronograph is the most collectible (and best known) watch to come from the Croton (and Nivada) stable. The Chronomaster was produced in a wide variety of case, dial, and movement executions throughout its production years. Today's watch is considered to be more desirable than your conventional Chronomaster for its combination of external and internal characteristics. Those include the broad arrow-style hands, the stepped sub-dials with radial numerals, and the hand wound Valjoux 92 movement ticking inside.
