The classic early 1950s Helvetia Gentleman's square face watch, this example keeping good time with a lovely champagne dial, with transferred Arabic numerals, and round markers.

Helvetia watches were originally produced by La Générale Watch Co., a company founded in 1895 by the founders of Omega. Known for producing robust, high-quality movements, Helvetia became a successful brand that provided watches for military forces and innovated with early water-resistant and shockproof designs. After flourishing for decades, the brand struggled and disappeared during the "quartz crisis" of the 1970s and 80s.
