・Case width: 43.5mm ・Arm circumference: 150-200mm ・Waterproof: 200M waterproof ・Movement: AGS quartz (power generation driven by arm movement) ・Replacement CORDURA ripstop nylon strap included explanation A Japanese watch brand that plans and manufactures products based on the concept of high-quality watches at reasonable prices. The Japan Air Self-Defense Force's ``Air Rescue Team'' (commonly known as the Air Rescue Wing) is said to be the ``last stronghold'' in rescue operations. The air rescue team model is a rescue watch developed for rescue team medics who work in harsh fields every day. This model was commercialized through crowdfunding in 2017 and sold out soon, but due to popular demand, it has been reprinted in a limited edition of 1,958 pieces. The exterior has a fearless appearance inspired by the Black Hawk rescue helicopter, and the dial is designed with the troop sign of the Air Rescue Team. The case back features the slogan That Others May Live - To Save Others and a gold design of the three aircraft that make up the unit. The movement uses an AGS system that generates electricity through arm movements. As long as you wear it on your wrist, the watch will never stop due to a dead battery. ■Function■ [1] The movement uses AGS quartz so that the watch will not stop due to a dead battery during rescue operations. Operates for up to 6 months when fully charged. [2] Tritium microcapsules are installed on the dial and hands. Ensures visibility even during long periods of darkness, such as nighttime open sea rescues. (Tritium is 12, 3, 6, 9 o'clock + hour and minute hands) [3] A pulsometer that can measure your pulse is printed on the bidirectional rotating bezel. The pulse of the person in need of rescue can be measured in a short time. (BASE30: Start measuring by aligning the red ▼ on the bezel with the second hand. The bezel memory at 30 pulses becomes the pulse for 1 minute.) [4] In addition to the standard metal belt, a replacement belt made of CORDURA ripstop nylon is included. Ripstop nylon is a strong nylon material that is woven into a lattice pattern of durable colors to prevent continuous tearing even if a tear occurs, and is used in parachutes, tents, etc. [5] This reprint model is limited to 1958 pieces, in honor of the year (1958) when the Air Rescue Squadron, the predecessor of the Air Rescue Squadron, was established.
