Marathon GSAR aka Government Search and Rescue large diver’s automatic. Just the right size at 41mm. Made in Switzerland, company based in Canada, “US Government” on the dial, sold to USA military. This tool watch is equipped with self glowing tritium tubes for visibility without needing charged. Powered by a Swiss made Sellita caliber SW200-1, although Marathon likes to call it the “M2” because of a signed rotor – ok, we know those are 2012 tactics, but let’s roll with it anyway. Truth is, you already know about this piece, so here you can get one slightly used to avoid paying full boat. Get it!
