The Nivada Grenchen and Croton Chronomasters are becoming a staple in vintage chronographs and for good reason. They’ve got the ingredients for what makes a collectible watch, a sporty case design, water resistance, a rotating bezel, and multiple documented variations featuring different dials and movements.

One of the most sought after variants belongs to the Nivada Chronoking, which added a date at 12 o’clock to the Chronomaster while keeping all that signature style. These tend to be a bit more scarce (and expensive) and are all equipped with column wheel Valjoux movements. Croton, Nivada’s rebranding for the US market (after a tiff with Movado) got in on the action too, but these watches kept the Chronomaster name rather than adopt the Chronoking moniker. The Croton Chronomaster Date versions are extremely hard to find (seriously, try to find another one) and this example even has the “exotic dial” with reflective rings on the subdials.

These were built back when watches were used as tools and as such they often show quite a bit of wear. While this Chronomaster certainly has been used as intended over the years, it’s still in very good condition. The case shows its original signature chamfers, and the rotating bezel insert is mostly unscarred. The dial and hands are in wonderful condition which can be seen through the like new recently replaced acrylic crystal.
