In fact, it's not that the strap is good or bad. Of course, those inferior ones will not be mentioned. Ordinary stainless steel is slightly more durable than belts. But according to the different wearing conditions, we can't draw a conclusion. I can only say that the correct way to wear, pay attention to custody and care, can last longer. 1. leather, pay attention to sweat corrosion, soaking in water, corrosiveness, etc. And pay attention to keep ventilation when wearing, which can also avoid skin allergies. You should take off your watch when you sleep. It is also necessary to avoid the times of wearing and taking off the watch and reduce the damage to the belt. 2. Generally, there is nothing wrong with the metal strap, and skin allergy should be ventilated.
