Certina KF 320 – Swiss Made – circa 1951–1952 – Stainless Steel – Sector Dial – Small Seconds Offered here is an exceptional and fully original Certina wristwatch dating from the early 1950s, fitted with the highly regarded in-house KF 320 (Kurth Frères) movement. This is a fine example of post-war Swiss watch design – elegant, perfectly proportioned, and increasingly difficult to find in such complete and well-preserved condition. Movement: At the heart of this watch is the in-house, manually wound Certina KF 320 calibre, signed “15 Jewels” and “Swiss Made”. This movement was manufactured by Kurth Frères, the historic founders of Certina, and is well known for its durability, precision, and robust construction. The movement presents beautifully, with clean bridges, well-preserved screws, and original finishing throughout. It clearly reflects careful ownership and proper watchmaker maintenance over the decades.
