Like all Mondaine products, they are based on the original 1940s Swiss railway clock, the work of (then) railways employee Hans Hilfiker. These watches are both available in black or white, with the Chrono offering a brushed steel case, coated bezel, illuminated display, full chronograph functionality and a leather strap.
By contrast, the Day is a more minimalist watch, but with the same steel case and contrasting bezel and leather strap. The Day retails for £210, the Chrono sells for £330.
Mondaine watches available now from the Watch And Jewellery Shop.
