Here, we have a robust Marathon 'CSAR' Automatic Chronograph Jumbo 46mm, known as Chronograph Search and Rescue (CSAR). First introduced in the 1990s, it was developed and specifie d by the Canadian Government for special Search and Rescue operations. A brushed 46mm stainless steel case curves over your wrist thanks to tapered drilled lugs, and a lug-to-lug length of 55mm and a case thickness of 17.5mm give the watch an impressive wrist presence. Down the right side we have the screw-down chronograph pushers with cross-hatch knurling and a large screw-down crown with cross-hatch knurling for grip protected by crown guards. The unidirectional 120-click bezel has thick knurling for ease of grip when wearing gloves and a black 60-minute dive insert holding a flat sapphire crystal AR coated above a matte black dial. An outer 1/100 of a minute Decimal scale is precisely executed surrounding applied Tritium Gas Tubes and MaraGlo baton indexes above large 12-hour Arabic numerals and smaller 24-hour numerals marking the hours; at 3 o’clock, we have a day/date window, at 12 o’clock a 30-minute register, at 6 o’clock a 12-hour register and finally at 9 o’clock a small seconds register. Thick syringe hands have Tritium Gas Tubes and MaraGlo for a distinctive green glow complemented by a tapered red arrow-tipped chronograph hand. We have the Marathon motif with H3 and the radioactive symbol. In 1973, the H3 and Radiation symbol was added to US military specification requirements; the H3 stands for radioactive Tritium, which gives that exceptionally long-lasting bright lume. On the reverse, a screw-down solid case back with the details of the watch around its edge and the Government specification ID numbers engraved for the following: ISO 6425, 26 MILLICURIES is the amount of Radioactive material in the watch, NRC ID- Nuclear Regulatory Commission ID number for Tritium, next is the General Services Administration contract number with the ID number for suppliers to government agencies, inside an Automatic ETA/Valjoux 7750, 25 jewels, beating at 28,800 beats per hour, this workhorse chronograph movement has quick-set date, hacking seconds and hand winding for your convenience. It comes paired with its 22mm brushed stainless steel 3-link bracelet secured by a signed deployant clasp and flip lock engraved with the Canadian Forces tri-service logo. All links and an additional 22mm NATO strap are provided, and the watch comes with this Marathon presentation box, spare bezel and paperwork. Show more
