・A urethane band may be stained by dyes present in or on clothing or other accessories. Since these stains may not be removable, avoid wearing your watch with clothing, purses, etc. that tend to transfer color easily.
・A urethane band may be deteriorated by solvents or moisture in the air. Replace with a new one when it has lost elasticity or become cracked.
