$ 3,000


The Chronomaster range of watches from Nivada Grenchen and Croton were produced when adventures and exploration were at the forefront of what was happening in the world and within the pop culture of the 1960s. Within the expansive world of vintage timepieces, there is no uncertainty that vintage tool watches hold a particular position in the minds of numerous collectors. The 1960s and 1970s were what we now know as the golden era of sports watch design where the form of a watch needed to meet its intended function to support the adventures that the watch was created for. Nivada Grenchen or Croton in the States was founded in Grenchen, Switzerland in the 1920s by Jacob Schneider, Nivada Grenchen was actually one of the first watch brands to manufacture automatic watches. Nevada also encompassed other modern wristwatch innovations, creating waterproof and “rustless” watches that would stand up to the rigors of the outdoor adventures they were creating a watch for.

DIAL & HANDS

The matte black dial is in overall exceptionally vintage condition, exhibiting only subtle age, namely some darkening to the dial around the hand stack but no notable damage. The tritium lume plots have achieved an even dark tan patina throughout, under U.V. light inspection none of the lume plots exhibit degradation but the 4 and 5 o'clock markers feature an odd texture from factory. The original "broad arrow" hands have been professionally restored with tritium to match the dial.
