The Classima 10857 is distinctive for its round 40 mm case in polished steel with a 4N PVD coating. Its crown and solid case back in polished steel complete the understated look. Its silvery opaline sun-satin dial features a barleycorn pattern, showcasing 4N gold-tone Roman numerals and indexes, as well as 4N gold-tone leaf hands. A date aperture at 3 oclock rounds out the dial. Powered by a quartz movement (ETA F06. 115), it offers a 4-year autonomy and is water-resistant to 5 ATM. Its interchangeable strap in dark brown alligator-patterned calfskin features a reliable spring bar system that allows it to be changed without the use of tools.
