The aquasport seams to be not sold in Scandinavia,only found one during 20 years.grateful if somebody have any information about this.
The Aquasport model was launched in the late 1930s and lasted until the mid-1940s. Early ones used the caliber 17.5 family; later ones were from the caliber 27 family. Most were manual-wind movements with stainless steel, screwback cases.
That's a nice example. Looks like 30mm? I'll guess it's a variant on the 17.5 caliber. Is it missing its center second hand?
