Manufactured in the 1940s, this is a rare and beautiful example of an unnamed “Zerograph”, featuring a stainless steel back, salmon dial, and a striking three-color scale design.
This is a simple chronograph operated via the button at the 2 o'clock position, which starts, stops, and resets the central seconds hand. When activated precisely at midnight, it enables time measurement of up to 12 hours.
There are various types of simple chronographs, such as Longines' stop-seconds, Rolex's Zerograph, and Venus Cal.103, among others. This particular piece is equipped with a rare movement—essentially a downsized version of the 29mm Landeron-Hahn reduced to about 23mm in diameter.
The salmon dial with its three-color scale features centrally oriented indexes, and together with its finely detailed design, offers a richly condensed and sophisticated aesthetic.
This recommended piece is in excellent preserved condition, boasting a beautifully toned salmon dial with crisp printing, a case with sharp edges retained, and includes its original leather strap and buckle from the era.
