A classic Japanese-made Seiko 5 Automatic, this vintage example features an original matte black dial with large Arabic hour numerals, a framed day-date display, and the iconic Seiko 5 emblem. Powered by the dependable Seiko Caliber 7009 automatic movement, it combines the practical day-date layout with the distinctive styling of vintage Seiko 5 watches.
Collector’s Note
This example retains its original Seiko dial, original Seiko 7009 automatic movement, original stainless steel case, and original/period-correct folded-link stainless steel bracelet.
The bracelet features B1297-E stamped end links. The fold-over clasp has been replaced with an aftermarket clasp.
The case-back serial number 370656 indicates July of a year ending in 3. Based on the serial alone, the watch can be dated to July 1983 or July 1993, so the exact decade cannot be conclusively established from the serial number alone.

The large Arabic numeral layout gives the watch a distinctive vintage character while maintaining the clean, highly legible design associated with Seiko 5 models.
Case & Bracelet
The watch retains its original stainless steel case with the characteristic vintage Seiko 5 case profile and slightly recessed crown positioned around 4 o’clock.
It is paired with the original/period-correct folded-link stainless steel bracelet, with B1297-E stamped on the end links.
Note: The bracelet’s fold-over clasp is aftermarket.
Case Back Details
The original case back carries the following markings:
SEIKO • 370656 • 7009-3181 • STAINLESS STEEL • WATER RESISTANT • JAPAN A
The serial number can be interpreted as:
* 3 — Year ending in 3
* 7 — July
* 0656 — Production sequence number
Therefore, the serial indicates July 1983 or July 1993. The serial itself does not provide enough information to definitively determine which decade.
The 7009-3181 marking identifies the Seiko movement/case reference combination.

Inside is the original Seiko Caliber 7009, a 17-jewel automatic mechanical movement operating at 21,600 vibrations per hour.
The movement is:
* Automatic / self-winding
* 17 jewels
* 21,600 vph
* Non-hand-winding
* Non-hacking
* Equipped with quickset day/date functionality
The day and date can be adjusted through the crown using the appropriate crown positions.

Important Note
This is a vintage Seiko with its original dial, movement, case and bracelet. The bracelet clasp is aftermarket. The production date is stated as July 1983 or July 1993, as the serial number identifies the year only by its final digit.
As with vintage mechanical watches, minor signs of age, wear, patina and previous servicing may be present. Water-resistance markings on vintage watches should not be interpreted as a guarantee of present-day water resistance. Please review all product photographs carefully before purchase.
