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. Appreciated for their slimness and their balanced proportions, Classima also offers ladies’ models. These watches are perfect for daylong wear. Depending on the model, the 31 and 36.5 mm diameter comes in polished steel, adorned with a diamond-set bezel, or in an 18K red gold capped steel version on the two-tone model. Their mother-of- pearl or white dials, graced with Roman numerals and a sun guilloché decor, admirably round out the feminine range.
