・ Because some titan bracelets use pins made of stainless steel, which has outstanding strength,
rust may form in the stainless steel parts.
・ If rust advances, pins may poke out or drop out, and the watch case may fall off the bracelet, or the
clasp may not open.
・ If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and
request repair.
