Seiko 5606-7192

Seiko Lord Matic (LM), 1968-1977. What it is, how to date it, how to check it's original, and what it's worth.

The Seiko 5606-7192 is a Seiko Lord Matic (LM). It runs on Seiko's calibre 5606, an automatic movement with 23 or 25 jewels, beating 28,800 times an hour. It can't be wound with the crown and winds itself as you wear it. Seiko made the 5606 from about 1968 to 1977. A step up from the Seiko 5, with 23 or 25 jewels and a faster beat. Kanji day wheels are common.

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 5606, made 1968–1977, a serial starting 35 means May 1973. Our Seiko Identifier works it out for you.

Is it original? The small dial code at 6 o'clock should start with 5606, 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 5606-7670 S.

What is it worth? A running 5606-7192 in average condition usually sells for about €150–260 in Europe; an original dial, a strong colour and the original bracelet push it up. Price guide

Most 5606 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
