Vintage Seiko Accuracy
Playing around with a few pieces on my timegrapher here. The beat error is a little wide, but this 1962 Seiko Cronos is a great example of how Vintage Seiko watches just keep on going

And this 1964 Seiko Champion isn't too shabby either.

Hi Adam,
Can you please explain the results a bit. The first one says 1.9ms for 18,000 beats, what does that mean for loss or gain of seconds per day? And the second one, the 1964, it says .4ms for 52 degrees, I’m not sure what that means at all. (I guess I can google timegrapher, let me know and I will) Love that 1964!!

Hi Kevin,
Ok the 18,000 is the beats-per-hour, and 52 is the lift angle - these two numbers alternate on the display. Different movements require different lift angles, but 52 is pretty standard if you don't happen to know the required lift angle for your movement. 1.9ms is the beat error, which means the balance wheel swings a little unevenly, but not horribly so (anything between 0.0 and 0.9 is good). Amplitude is basically how far around the 360 degrees the balance wheel turns. Over 300 is great, 275 is good, and I'd say 230-240 is acceptable, and anything over 200 is ok if you want the watch to function. (others may disagree, and I'm really talking only about Seiko movements). The "Rate" is the seconds lost or gained per 24 hours (resting dial-up in this case) Hope that helps!

Thanks Check out the caseback, January 1964 and barely worn . . . I think this was in storage for a long time.

That is really cool and nice to see the great shape it is in. I love my Seikomatic, I’ll try to get some shots of it on this week. He might like a cousin to hang out with. Let me know if you’re interested in finding it a new caregiver some day. I googled the seahorse and Seiko’s and ended up looking at a 1964 Seiko Seahorse which had a great story: https://www.fratellowatches.com/seik...-review-62mas/ Sent from my iPhone using Tapatalk |

A Seahorse logo was used on the casebacks of early waterproof handwinding models, and a dolphin was used on the back of waterproof automatics.

For the record, here's another one I just got...a 1968 Sportsmatic, putting up good numbers right out of the barn, and doing even better on the wrist.

I like how you have wrapped the metal part on your timegrapher to prevent the watches from getting scratched!

Beats per hour is about 130 Beat error is fairly high (1.3) Amplitude is still above 280 The rate is not so good, but enough. (-15s/d) My wife stops once in a while the movement an sets up the exact time newly

Here's another one. A 1972 LM, which has just confirmed its timegrapher numbers by gaining about two seconds over the course of a week on the wrist

Yes thank you for showing these vintage watches!
I think we would have a good chuckle if we knew what they cost in the 1960s.

No suprises here, in that period seiko produced the worlds most accurate mechanical watches and swept the chronometer awards
My king seiko (while not 0spd, keeps time as well any any of my modern pieces
