Do obscure quartz watches count? Ignore the one on the left because it's a current model.
The watch on the right is a Swiss-made mid-'70s Westime and used to be my dad's watch. It is in working order. Obscure now because it's an LED watch.
The Citizen in the middle is from the mid-'80s. I got it as a kid and I still have it and it works. It gets a new battery every 3 years. The module is still in production but the metal case with a plastic shroud was available only for a short time. Nearly impossible to find now because it's obscure.
For completion's sake, the watch on the left is a dirt-cheap Casio AE 1200 module in an aftermarket SKX Mod 316L case with sapphire crystal. Great watch when traveling as it has a world time feature. Obscure because it's a modded watch.
