Conquer demanding terrain and feel amazing with a rugged timepiece as bold and active as it is tough. Designed to work even in the harshest environments, the RANGEMAN GPR-H1000 from the MASTER of G line is a truly tough piece of outdoor gear. With a mud-resistant structure to keep out fine dust and dirt, it is designed to withstand the most punishing conditions and the worst weather situations. This muscular timepiece is equipped with a heart rate monitor, built-in GPS functionality, and a high-definition, high-contrast memory-in-pixel (MIP) LCD for an easy read. The case is guarded by sizable metal components on the left and right, protecting the GPS antenna and six sensors inside, to deliver what you need for a wide range of activities. The trekking function allows you to check your heart rate while on the move so you can keep track of your physical condition during workouts. Check the tide graph for low and high tides to get the most out of water sports. Enjoy all this functionality, with no sacrifice in comfort. The soft urethane band delivers a comfortable fit that your wrist will love and is textured on the top side so that even wet fingers can tighten it without slipping. The case, bezel, and band are made with bio-based resin, a material expected to help reduce environmental impact. With the engraved silhouette of the RANGEMAN wild cat character on a band piece, every detail of this timepiece exemplifies the spirit of this MASTER of G line of specialty watches.
