This new addition to the PRO TREK PRW-3100 series uses materials selected to enhance PRO TREK level usability.
A sapphire crystal improves durability and readability, while a field composite band improves overall performance. The STN LCD also enhances readability.
Field composite band
This composite band is made of urethane components that have metal inserts, and fine resin components. Fine resin is used for the center elements, while urethane H-pieces have metal frames embedded. A double-lock buckle has a slide adjustment mechanism made of titanium alloy. The result is a light weight band that puts less load on the wrist during long-term wear, without sacrificing durability.
