With the diversification of case designs, there are cases with square or rectangular shapes, which are formed into a square shape by press processing and then finished into the final shape by grinding. Grinding was done manually by relying on intuition, that is, pressing the case against a grinding belt or whetstone by hand, so if one side was over-sharpened or bent, the left-right and top-bottom balances could become unbalanced when viewed from the dial side. The yield rate was poor due to the product being distorted and the shape of the product being inconsistent.
