Manufactured in the 1940s, this rare Jules Jürgensen chronograph is equipped with the Landeron Cal. 13 and housed in a solid 14K yellow gold case with a two-tone dial featuring a three-color scale design. While most Jürgensen chronographs from this era are seen with steel cases and Valjoux movements, this example stands out as an exceptional piece with its solid gold case paired with the Landeron Cal. 13.
Its concave case design, reminiscent of the Patek Philippe Ref. 130, is of non-waterproof construction yet exudes a substantial presence. The finely executed two-tone dial with three-color scales offers both excellent legibility and refined aesthetics—details that reflect the craftsmanship unique to solid gold models.
The Cal. 13 movement features shock protection and a column wheel mechanism in a compact layout, a high-grade chronograph caliber also adopted by Breitling and Heuer during the same period. This is a rare and remarkable timepiece in every sense.
