Seiko 6349-5190

Seiko Seiko 5 dress / square cases, calibre 6349. What it is, how to date it, how to check it's original, and what it's worth.

The Seiko 6349-5190 is a Seiko Seiko 5 dress / square cases. It runs on Seiko's calibre 6349, an automatic movement with 23 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 6349 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 6349, 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 6349, 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 6349-5210 R.

What is it worth? A running 6349-5190 in average condition usually sells for about €70–130 in Europe; an original dial, a strong colour and the original bracelet push it up. Price guide
