This rare 1930s Geneva sport baby chronograph features a 28 mm Staybrite steel case manufactured by Adams Watch Inc Switzerland, a renowned case maker for Swiss chronographs of the pre-war period. The black sector dial with copper print remains untouched, showing telemeter and tachymeter scales and evenly balanced registers at 3 and 9 o’clock.

It is powered by the Geneva Sport 23.7 manual column-wheel caliber, a mechanically sophisticated and well-preserved movement. The articulated hexagonal hinged lugs, often associated with early military and sports chronographs, provide improved wrist comfort and a distinctive visual presence.

Offered with two Italian hand-crafted Torre Straps and two vintage 10 mm lizard straps. Overall condition is excellent, preserving both aesthetic originality and mechanical integrity. A highly collectible example with strong historical and design appeal.

Case: the case is round and made of Staybrite steel, a corrosion-resistant material commonly used in pre-war sports watches. Its hexagonal articulated lugs offer not only improved comfort on the wrist but also a distinctive design feature often found in early military and sport chronographs. The caseback is snap-on and internally signed "Adams Watch Inc – Switzerland," confirming the provenance from a notable Swiss case manufacturer.

Dial: the black sector dial with copper print exemplifies the graphic refinement of the 1930s. It features balanced subdials at 3 and 9 o’clock, as well as telemeter and tachymeter scales. The printing remains crisp and untouched, showcasing both originality and aesthetic harmony.

Movement: the watch is powered by the Geneva Sport 23.7 caliber, a manual wind, column-wheel chronograph movement. This type of mechanism is highly regarded for its precision and traditional Swiss watchmaking complexity. The movement is in excellent working and visual condition, consistent with the period and quality craftsmanship.
