A great thing to have on hand are these nylon case back closing dies for extra large watches. 8 supplement dies (or replacement) for watch case back presses Prestige, Prestige New and GT. 3 plan dies with diameter 35, 40 and 45mm and 5 concave dies (rotatable) diameter 40, 42.5, 45, 47.5, 50, 52.5, 54, 55, 56 and 57mm. Nylon won't scratch or mar the watch case when closing so we think it is the better choice for hobbyist watchmaker, (better as aluminum dies). Supplied without a watch press tool.
