This week's FriDiver. Purpose-built for military Search and Rescue units, it is standard issue for U.S. Marine Corps SAR personnel. It's powered by an ETA 2824-A2 and by lucky happenstance mine happens to be running well within Chronometre timekeeping specs. Night illumination is provided by fifteen tritium gas filled tubes, plus an ultra-bright Luminova triangle at 12 O'clock on the bezel. Today I'm wearing it on a 20mm grey ToxicNATO strap.
It's battered and worn and belonged to my father, it was his work watch. I found it at the weekend, it's not been used for at least seventeen years, I wound it up and have been wearing it ever since.
