In true mid-century chronograph tradition, the dial includes a tachymeter scale (Base 1000) and a 30-minute counter marked with three-minute divisions, a period feature once used for timing long-distance telephone calls. These historically documented elements, described in The Main Types of Chronograph Explained by Their Dials (1951), reinforce the model’s deep archival grounding.
Paired with a rich blue strap, this reference embodies understated refinement and pays tribute to the elegance of Lebois & Cie’s mid-century chronographs.
