Certina – Argonaut Automatic “TV Case” – Cal. 25-651 – Ref. 5801-167 – 1960s/70s A distinctive vintage Certina Argonaut automatic wristwatch, powered by the respected in-house Caliber 25-651. This model captures the bold transition in Swiss watch design from the late 1960s into the early 1970s, featuring the iconic TV-shaped cushion case — a form that has become increasingly appreciated by collectors for its strong architectural presence and unmistakable period character. About Certina Founded in 1888 in Grenchen, Switzerland, Certina is one of the historic manufactures of Swiss watchmaking. Unlike many brands of its era, Certina developed and produced its own movements in-house, building a reputation for durability, reliability, and technical seriousness. The brand’s famous DS (Double Security) concept, introduced in 1959, further reinforced its standing as a maker of robust and well-engineered watches. Often regarded as an insider’s brand, Certina remains highly respected among collectors for offering genuine manufacturing pedigree and strong technical quality without the inflated image-driven premiums seen elsewhere. The Argonaut Line The Argonaut name represents one of Certina’s most versatile and attractive vintage lines. From dive watches to Valjoux-powered chronographs, the Argonaut range covered a broad spectrum. Yet the three-hand automatic models such as this one offer a particularly appealing balance: distinctive late-1960s / early-1970s design, practical everyday wearability, and a true in-house Swiss movement — all without the significantly higher cost associated with vintage chronographs. Dial Silver dial with a subtle vertical texture that gives the watch a refined and understated appearance. Applied faceted baton hour markers and matching hands create a clean, elegant look, while the framed date aperture at 3 o’clock adds a classic functional touch. Signed: CERTINA AUTOMATIC Argonaut T SWISS MADE T The dial shows natural ageing and light marks consistent with its vintage character. Case Stainless steel cushion / TV-shaped case Approx. 35 mm excluding crown Reference: 5801-167 Serial: 6805664 The caseback bears the Certina turtle logo, and the crown is signed.
