EVOLUTION OF THE FIRST NIVADA CHRONOMASTERS (VENUS 210)

CHRONOMASTER? NO, CHRONOGRAPH

The models fitted with the Venus 210 caliber are the first representatives of the Chronomaster dynasty, yet they don’t have that name on their dials. Instead they are inscribed CHRONOGRAPH.

The first watches appeared in 1961. They are immediately recognizable by their small pushers and their wide broad arrow hours hand. These are perhaps the most emblematic of the Chronomaster models and the most exemplary in the collective imagination of collectors.

REFERENCES

We have identified 5 references for these early CHRONOGRAPH models equipped with the Venus 210:

  • NIVADA GRENCHEN: ref. 8221 M 8719 and ref. 8221 M 9688 (both with 7-figure serial number engraved on the caseback).
  • CROTON: 3 different ref. 105 (105 with 5-figure serial number + 7-figure serial number; 105 with 5-figure serial number + 5-figure serial number; and 105/8987 with 5-figure serial number).

DIALS

Many different dials have been fitted on the Chronomasters. But only 7 of them can be found on CHRONOGRAPH models with Venus 210. They all have radial flat subdials and painted markers.

The main differences between those 7 dials are regarding the NIVADA GRENCHEN or CROTON NIVADA GRENCHEN name, and the position of the SWISS mention:

  • A1. NIVADA GRENCHEN – CHRONOGRAPH Two Lines
  • A2. CNG – CHRONOGRAPH Low SWISS Brown
  • A3. CNG – CHRONOGRAPH Low SWISS
  • A4. CNG – CHRONOGRAPH Double SWISS
  • A5. CNG – CHRONOGRAPH High SWISS
  • A6. NIVADA GRENCHEN – CHRONOGRAPH High SWISS
  • A7. CNG – CHRONOGRAPH Aligned Ns
