I've always liked watches with slide rules, although I need magnifying glasses to see the small numbers these days! This Seiko quartz must be about 15 years old but still works perfectly.
I had no idea you could get watches with slide rules built in. I'd have to learn to use a slide rule, but that's on the list of things I want to learn anyway, just below welding and hypnotising alligators.
they remodelled this watch as the Sinn Arktis 206 ...........but it is slightly different than the 203 , worn in Siberia back in 2007 , confirmed temperature of -52c , watch performed perfectly
