A prize-winning design from 1962, the Classic Ultra-Thin OM2 Watch by Ole Mathiesen is the epitome of cool, mid-century sophistication. The 35mm gold-plated case features a convex, sapphire crystal—a signature of Mathiesen’s watches. The Swiss quartz movement, uncluttered dial with 12 index lines, date window, and fine black leather strap all contribute to the Classic Ultra-Thin OM2 Watch’s harmonious, timeless design.
