This change can be seen engraved on movements from that time on (see Part 2. Main components, Chapter 2. Caliber, page 34). It also appeared to coincide with the introduction of a new identification, CRO-

that
NIVADA
GRENCHEN watches sold in the United States seem to have been marketed by CROTON WATCH CO. INC. rather than directly by NIVADA SA. They are in fact given a reference code that is specific to CROTON (see Chapter 3. Understanding the references of Chronomaster models, page 23).
Story’s end In the 1970s, the watch industry had to confront the quartz shock immediately after the oil crisis of 1973. It was a difficult time for the whole sector and proved fatal for some brands that lacked the means to fight off Asian competition. Among them were NIVADA SA and CROTON TIME CO. INC., which failed to cope with the times and had to give up their businesses. The two brand names have changed hands several times since and still exist today, but they have nothing in common with their prestigious predecessors. That is why it is impossible to find archives or any official information about models that came out before the end of the 1970s.

On this reference can be found the rare transitional dial type A4. CNG – CHRONOGRAPH Double SWISS, in which the second SWISS inscription is often invisible because it is situated too low beneath the minutes scale on the dial (see page 170).

CNG – CHRONOGRAPH Aligned Ns The CROTON brand name was probably added to the dial as an afterthought. The type size of CROTON turns out to be slightly bigger than that of NIVADA GRENCHEN, and the letters N of CROTON and GRENCHEN are aligned.

Chronomaster Aviator Sea Diver: this singular name belongs to one of the most original professional watches of the 1960s, combining an unparalleled number of functions with a timeless design. Created in 1961, this chronograph was produced for around ten years under several brand names, through a partnership between the Swiss company NIVADA SA and the American firm CROTON WATCH CO. This led to some of its dials bearing probably the most complicated name in watchmaking history: CROTON NIVADA GRENCHEN Chronomaster Aviator Sea Diver. Thanks to the authors’ trademark rigorous methodology, the signature of the “ONLY” reference works, this book reveals the incredible diversity of the Chronomaster models. It is intended both as an initiation for connoisseurs of exceptional watches and as a reference guide for collectors. This legendary watch will doubtless thus regain the place it deserves among the most desirable 1960s chronographs.
