Among the full-scale outdoor gear PRO TREK, the new model PRW-70 will be released from the "Multi Field Line" that supports activities in various outdoor fields. By adopting a metal layer structure that sandwiches the watch body with a metal bezel and a case back with an integrated lug, it is possible to achieve a size that fits comfortably at hand. In addition, a square side button with a special pattern that improves the hold feeling of the finger and a button guard that prevents button malfunction are adopted to realize high operability in the field.
