After receiving orders from the government and military, several companies including our company sell only the excess production to the general public. MARATHON watches are not intended for sale to the general public, so they have a very high CP (cost performance). A special watch developed for Canada's TSAR (Search and Rescue Team) rescue team. The dial uses tritium vial technology that does not require luminescence. Achieves stable luminescence for approximately 15 years. "H3" at 9 o'clock is the symbol for tritium. Radioactive mark inside the 3 o'clock position. *The amount of radioactivity is extremely small (below daily life levels), so there is no harm to the human body. The maximum width including the bezel, crown, etc. is 46.0mm. The case is machined from solid 316L stainless steel. The crown is of course a screw-down design, and it is a large type that is easy to operate even while wearing gloves and has a non-slip finish. The sapphire crystal is also 2.8mm thick and robust. The rotating bezel is a counterclockwise ratchet type (120 clicks). It is useful not only for diving but also for measuring the passage of time in daily life.
