Croton Nivada Grenchen Chronomaster

Croton Nivada Grenchen Chronomaster

Nivada hit a legal hurdle when trying to sell in the USA, thanks to Movado who felt that their names were too similar and would confuse consumers. A judge ruled that adding ‘Grenchen’ to the title would suffice, and so watches sold thereafter are labeled as such.

In 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 CASD is a classic 1960s diver going through several iterations (like the Omega Speedmaster), with tritium, radium, broad arrow and baton hands, brown chocolate aged dials etc etc. They now have a big following, greatly enhanced by the recent Chronomaster Only book in 2018. The model has recently been reissued by Nivada in both manual and automatic versions but retaining a faithful appearance to the original.

Model One - straight lugs 1961 to circa 1971

This is the version covered in the Chronomaster Only book and most popular with collectors. They will appear with a variety of brand names. There are 5 main versions depending on the movement:

Venus 210

The very earliest versions have Chronograph rather than Chronomaster on the dial. Up to 1963 the dials and hands are radium with no T on dial. They are often found with browning dials due to a faulty lacquer used by Singer, the dial manufacturer. See also the VJ7733 models for the same problem in late 1969/70.

Valjoux 92

Short term replacement for the old Venus 210 movement. Quickly replaced by the VJ23

Valjoux 23

105-9870 VJ23 Croton only tritium dial circa 1966

The movement seen in most Nivada versions from 1963 to late 1960s.

Landeron 248

Used by Croton post 1966.

Valjoux 7733

Seen in all the late 1960s models onwards. Robust reliable movement used by hundreds of watch manufacturers and retailers.
