Fascinatingly flat watches are one of Jean Marcel's particular strengths. The new Optimum collection, which celebrates watch minimalism at its finest with its extremely slim cases, also follows in this tradition. With a total height of only 7.5 millimetres for the three-hand automatic watches and just 5.6 millimetres for the Optimum réduit, they are each one of the flattest mechanical wristwatches of modern times. Remarkable for this extremely low height are the two sapphire crystals and the water resistance up to 5 bar.
