The PRT-B50T features a light grey coloring, which is offset by an orange second hand and north indication on the large rotary bezel that not only enhance visibility but also add attractive accents.
The large Arabic numerals on the multi-dimensional face enable easy, at-a-glance time reading, while metal parts combine to create a look of quality and elegance. The fine resin back cover is made using tough, lightweight glass fibers in a structure that integrates the band connection lugs, and button guards protect against operational error. Both of these features enhance the ruggedness of these models. The large rotary bezel allows easy operation outdoors, even while wearing gloves, and adds to the wild look of these designs.”
