The oversized reference 1897 is without any doubt one of the rarest wristwatches to come to auction as only a handful have appeared on the international auction market in the past 20 years, the present lot being the only one known with black dial. Produced in the 1930s, the reference 1897 with its large case and superbly crafted, charismatic dial has an avant-garde aesthetic that is as modern today as it was nearly a century ago. In addition to the oversized case, the present example has its original black glossy dial, which beautifully complements the copper-colored numerals and matching hands. This watch remains in superb and unrestored condition. The case has seen some, but respectful wear and the few scratches visible on the side of the case are modest signs of aging for a watch that is over 80 years old. The present timepiece is a rare treasure that will certainly impress collectors and aficionados alike.
