Why Bronze? When you first get the bronze watch, it is slightly rose gold in color. When you wear it for a month or more, the case will gradually darken and become very retro (I prefer this). Of course, the depth of the case color and the oxidation time vary according to each person's wearing habits. Interestingly, if you don't like the color of the oxidized case, you can remove the watch strap and soak the watch head in Coke or ketchup for a few minutes and it will return to its original color. This process was actually tried by our team, and it was very interesting!
