The Classima collection, composed of watches in steel, 18K red gold or made of red gold capped steel on the two-tone models, fitted with alligator straps or steel or two-tone bracelets, is driven by mechanical self-winding movements, mostly visible through the sapphire crystal case back, or by Swiss-made quartz movements. Available in 39 and 42 mm diameters, this collection has been redesigned, in 2015, in a 40 mm-diameter version intended for men keen to wear an elegant and discreet watch. Enlivened by a variety of dials, including the iconic line guilloche decor, these watches admirably combine masculine understatement with technical sophistication.
