I got this at a garage sale a few years back. Wore it from time to time and it kept amazing time honestly better than 20spd. But not knowing the history of it I stopped wearing it. Sent it out for service and got it back a few weeks ago. Its a retirement watch from a company called the same as my last name 25 years of service. The guy died and his kids were selling everything for dirt cheap. This was in a bag of junk jewelry for 3 dollars. Inscription says 1974 so its at least 46 years old. Has quick set date too so now this will be in my rotation regularly!
