I wonder if you have thought about it, whether it is Roman numerals, Arabic numerals, diamonds or studs, our watches only have a 12-hour scale instead of a 24-hour scale? why? Xiaobian satisfies everyone's curiosity. It is convenient to watch the time. Generally, men's watches are 38-44 mm, and women's watches are only 20-36 mm. The dial is very small. If it is made with 24 time scales, it is dense numbers. It is difficult to see the time clearly and affect the beauty. Inconvenient to wear and use. Besides, for the same dial area, the number is increased to 24, and the font must be larger, which increases the production cost. Therefore, no matter from the wearer's perspective or the manufacturer's perspective, the 12-hour dial is more suitable.
