Last week it what I recently bought. Now after cleaning Cal 265, some light screw head polishing, hand and marker cleaning (rose), and a new crystal, it is taking me out for vindaloo at lunch time.
Probably the cheapest watch on WRUW today but I quite like the retro square look and if I happen to drop if from 10m I know all will be good 😉
Casio G-5600E-1DR
I might have you beat. Early 70s Timex, $10 at a junk shop. It is a watch I never have to worry about, and surprisingly it keeps good time. Been running continuously for a month and still accurate to the minute.
