I have never seen a CASD in a better condition than this one. To summarize, there is only one flaw: a little mark on the tritium lume on the hour hand that is hardly seen by the naked eye. Now, the case is sharp and unpolished. The bezel is in incredible condition with just a few marks. The dial, the true protagonist here, is untouched and free of any marks. Both the red chronograph hand and the red regatta counter still preserve their true hue. The watch is signed by Croton in the dial, movement bridge and case back. The movement, a Landeron 248 caliber, works as a charm -sets and resets smoothly-.



Croton, which initially was found in 1878 by Jacob Horton in New York, has a direct relationship with Nivada (and thus we can see the same models branded by either firm).

The Chronomaster model was introduced in the early 1960s specially for the U.S. market. Their target customers where engineers, airline pilots, race car drivers, skin divers, scientists… That is why, for the time, this watches were produced in rather large cases, 38mm, for a better visibility.
