Product Description "Power Reserve Vintage" reproduces the atmosphere of the 19th century Potato Watch made by Moritz Grossmann. The dial uses the same silver as at the time, and the logo and Roman index are reproduced in the same way as at the time. I would like you to pay attention to the thin and beautiful handmade needles. The minute hand, in particular, is 0.1 mm at its thinnest point and just 0.05 mm at its tip. The hands are tempered blue instead of the brown violet used in existing Grossmann models. By matching the color of the power reserve indicator, the presence of the power reserve indicator is blended into the classical style without any discomfort. The movement to be installed is a hand-wound Cal.100.2. It features a time adjustment mechanism with a pusher that switches to time adjustment mode as soon as the crown is pulled out, and the crown returns to normal without having to push it in by hand. After that, pressing the button at 4 o'clock shifts to normal mode, and the second hand begins to move and start ticking the time. This is a unique mechanism designed to prevent the hands from changing position when the crown is pushed in. Parallel import goods with no written date in the warranty card. Since it is Unworn, we only check the movement.
