Urethane band:
A urethane band is susceptible to discoloration from light, and it may deteriorate from contact with solvents or humidity in the atmosphere. If bands remain wet and in highly humid locations or are exposed to sunlight for extended periods, the rate of deterioration may accelerate and some cracks may appear on the band surface. In addition, a translucent, white, or pale colored band easily adsorbs other colors, resulting in color smears or discoloration. Care should be given to the condition of polyurethane bands, which are often worn for marine sports or outdoor activities.
Cleaning method:
Wash off any dirt with water and dry throughly with a dry cloth (protect the watch head from water splashes by wrapping it in plastic wrap etc.).
* When the band loses elasticity, please contact an Authorized Seiko Service Center to replace it with a new one. If you continue to use the band as it is, it may develop cracks or become brittle over time.
