A watch is usually a mechanical watch, and if it’s a mechanical watch it all works on gears, and the watch will be marked with how many diamonds the watch has. The number of diamonds does not mean how many diamonds the watch has, but how many gear shafts the watch has with diamond eyes. Usually replaced with synthetic diamonds, because synthetic diamonds are resistant to wear and tear, so the more diamond eyes the watch has, the longer the watch’s relative running life.
But the gears of a watch can’t be machined with such a hard material as diamonds, it can only use steel for the axle. The smaller the watch, the more bookish it is, the thinner the axle, and the tens of thousands of revolutions per day are entirely dependent on the minute amount of oil inside the drill eye to reduce wear, and once the oil dries up and the axle is in dry wear, the watch’s life span will be up after a few years.Warm reminder: The latest market news is always available, please follow LuFuture.com app.
