Good pocket watch by Vacheron Constantin, circa 1900.
Diameter is 50mm, weight is 83 grams.

Vacheron & Constantin have a long tradition of striving to create highly precise movements without losing the sight of the fact that they must also serve their intended purpose as wearable timepieces. With this principle at the forefront of their production for methodology Vacheron Constantin decided to create the Chronomètre Royale.
The name “Chronomètre Royal” was registered on May 28, 1907, under the No. 22 193.
