Vintage Late 80s World Time Casio W-50U. : r/casiovintage
Casio] My A500WA-1 that I've had for over a year now and my father's old W-50U (sadly the upper spring bar broke off around 20 years ago and damaged the watch case) :
An old watch repair shop had an original F-84 strap for my W-50U. So happy! : r/casio
Casio W-50U] Definitely not made in Switzerland but definitely cool! : r/Watches
