Cro WatchesSeiko 6319-8000
Seiko Seiko 5 (21-jewel sister of the 6309), calibre 6319. What it is, how to date it, how to check it's original, and what it's worth.
The Seiko 6319-8000 is a Seiko Seiko 5 (21-jewel sister of the 6309). It runs on Seiko's calibre 6319, an automatic movement with 21 jewels, beating 21,600 times an hour. It can't be wound with the crown and winds itself as you wear it, and the seconds hand keeps running while you set the time. Seiko made the 6319 from about 1976 to 1988.
How old is it? The first digit of the serial number on the caseback is the last digit of the year, the second is the month (1–9, then O, N, D). On a 6319, made 1976–1988, a serial starting 15 means May 1981. Our Seiko Identifier works it out for you.
Is it original? The small dial code at 6 o'clock should start with 6319, like the caseback. If it starts with another number, the dial was made for a different model (a replacement dial). We have seen this reference with dial code 7009-6210 R1.
What is it worth? A running 6319-8000 in average condition usually sells for about €60–130 in Europe; an original dial, a strong colour and the original bracelet push it up. Price guide

Questions
Can I wind a Seiko 6319-8000 by hand?
No. The 6319 winds itself as you wear it. To start it, move the watch gently from side to side for 20–30 seconds.
How do I set the day and date on a Seiko 6319-8000?
Most 6319 watches either change the day when you press the crown, or have a quickset when you pull the crown out one click. Never change the date between 9 pm and 1 am. Step by step: crowatches.com/seiko-set-day-date.html
