Without any extension or added thickness, the strap ensures no peeling or fading. It can be freely re-gilt. The case, measuring 13mm, is consistent with the authentic product. The precious metal dial is perfectly molded in 1:1 ratio to the original. It utilizes the Shanghai 3255 integrated movement, providing a power reserve of 72 hours.
