My brother-in-law is in town…he’s somewhat of a watch guy and he digs Seikos. Anyway, he fairly recently acquired this Seiko 6106-8237. It looks like it’s from the 7th month of 1971 based on the serial number on the caseback. He recently had it serviced…but we can’t figure out how to set the day and date…the crown only has one detent [that we know of] and we can set the time. Any ideas? Thanks in advance.

Crown should push in, hard (deep) push sets day and date, gentle push (not all the way in) sets date only.

OK…I gave it the old college try…AND IT WORKED!!!

The FUN METER is pegged at MAX!!!

THANK YOU kind sir for that direction! My brother-in-law as well as myself had no idea regarding how that “push mechanism” worked…or that it existed. We are now schooled in this area of vintage Seiko horology THANKS TO YOU! 👍

I love the 6106 and 5126 movements that push in! Way more fun than pulling the crown to set the date IMHO.

The date on my Zodiac Astrographic SST from '72 works by pushing the crown in. Must be an early '70's thing.

It’s a much easier way the change the date, nowhere near as fiddly, don’t really know why it didn’t catch on

The Longines cal 505 (date only) has a similar date advance system, which I only discovered by chance.

Having set the date the ‘old fashioned way’, I couldn’t work out why, when I pressed the crown in, the date jumped ahead …..

As with @blufinz52's Zenith, another late 60s early 70s movement.
