Notes on skin 

irritation and allergy

Skin irritation caused by a band has various reasons such as 

allergy to metals or leathers, or skin reactions against friction on 

dust or the band itself.

Notes on the 

length of the band

Adjust the band to allow a little clearance with your wrist to

ensure proper airflow. When wearing the watch, leave enough

room to insert a finger between the band and your wrist.

Polyurethane band

○

A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or atmospheric humidity.

○

Especially a translucent, white, or pale colored band easily adsorbs other colors, 

resulting in color smears or discoloration.

○

Wash out dirt in water and clean it off with a dry cloth.

（Protect the watch body from water splashes by wrapping it up in plastic wrap etc.）

○

When the band becomes less flexible or cracked, replace the band with a new one.

○ Refrain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, 

and when working with water even if the watch itself is water-resistant enforced for daily use 
