Croton/Nivada "Chronomaster" chronograph [ca. late 1960s]
- Movement: hand-wound Valjoux 72 chronograph with column-wheel switching.
- Case: stainless-steel, ~40mm Ø.
- This is the North American version of the Nivada Chronomaster - Croton was Nivada's US importer/distributor and used their own brand on this side of the pond.
- Most variants of this watch are 2-register chronographs powered by a variety of Landeron or Valjoux movements, ranging from no-frills movements such as the Valjoux 7733 up to fine movements such as the Valjoux 23 and 92.
- This particular example is quite rare: it's equipped with a 3-register Valjoux 72 movement. So the 12-hour register on this movement takes the place of the verbose text/branding that appears on lower-half of the dial of the commonly available 2-register variants - here are some examples. The net result is a very functional "long-playing" chronograph and a very crisp, clutter-free dial.
i gave this watch to a good friend -- here it is "in action"
