A model with a design motif of "The design is based on the theme of the bright red fire fall phenomenon that appears only when the conditions are met several times a year at El Capitan in Yosemite National Park a sacred place for climbers. - A waterfall of fire that looks like orange lava flowing down a precipice is expressed by sharply shining red deposition on the rim of the windshield sapphire glass. - Together with the blacked out titanium band bezel and back cover by IP processing it creates a scene of a waterfall of fire that can be seen miraculously on the jet-black steep cliffs. - PRW-60YT adopts newly developed red vapor deposition for the red line on the top of the index - The liquid crystal adopts red light emission that does not impair dark adaptation. - Useful for checking the time and data at night - The PRW-50YT uses a gray IP that expresses the darkness of dusk for the bezel and band to express the dusk and pursue a metallic and luxurious finish. - In addition the Arabic index on the dial uses newly developed phosphorescent silicon. - The three-dimensional convex shape reacts to UV light and enhances visibility at night. - The digital PRW-30YT uses a newly developed liquid crystal processing to illuminate the entire liquid crystal in red. - Combined with a bold font it has been carefully designed as a real gear that emphasizes visibility and does not interfere with the dark adaptation of the eyes at night. - Fire Fall is a rare natural phenomenon that can only be seen when various conditions such as the time of day and weather are met from winter to early spring. - While maintaining the functionality of the PRO TREK a model that expresses this majestic natural phenomenon superimposed on the model of the climber line is now available. ・ Tough solar (solar charging system)・ 10 ATM water resistant function Radio wave reception function: Automatic reception (maximum 6 times/day) (Chinese radio waves maximum 5 times/day) / Manual reception supported areas: Japa..
