Favre-Leuba Deep Blue (59973) – Chrono Swiss Watch

Vintage 48mm x 42mm Favre-Leuba Deep Blue (59973) The Favre-Leuba Deep Blue emerged in the late 1960s, during a period when professional dive watches were becoming essential tools rather than fashion pieces. Favre-Leuba—one of Switzerland’s oldest watchmaking houses—introduced the Deep Blue as part of its push into robust, purpose-built sports models. The watch stood out for its impressive water resistance for the era, its bold, high-contrast dial designed for underwater visibility, and its signature cushion-style case that balanced durability with a distinctive aesthetic. Over time, the Deep Blue became one of the brand’s most recognizable vintage divers, reflecting Favre-Leuba’s broader commitment to technical innovation and adventurous design. Today, it’s appreciated by collectors for its characterful looks, solid engineering, and its place among the classic Swiss dive watches of the late ’60s and early ’70s.
