XB.3729.ECO Luminox Bear Grylls Survival 3720 Sea Series watch Luminox Bear Grylls Survival 3720 Sea Series

For true adventurers and militaries, the Luminox manufactory has designed the Bear Grylls Survival 3720 Sea Series XB.3729.ECO watch. It is a rugged device that should become an essential piece of equipment during survival. This is evidenced by the applied Rule of Threes, which allows a person to survive in extreme conditions, viz: 3 minutes without oxygen, 3 hours without shelter in extreme weather conditions, 3 days without water, 3 weeks without food. The model for this is distinguished by its solid workmanship, lightweight durable materials and practicality. It consists of an orange rubber strap, a brown envelope created from #TIDE plastic made from recycled plastics fished from the ocean. The advantage is undoubtedly the tritium gas backlighting (LLT), which will make the watch face legible at any time of the day or night. Additional conveniences include the "3" numeral coated with super-LumiNova compound, a screw-down crown and screw-down steel caseback, as well as a day-of-the-month date counter. The safety of the dial is ensured by hardened mineral glass, which reaches 550-650 HV on the Vickers hardness scale. Water resistance counts 200 meters.
