A distinctive vintage Seiko 5 Automatic, this example showcases the characteristic TV-screen/cushion-shaped case design that made many Seiko watches of the 1970s instantly recognizable. Powered by Seiko’s dependable Caliber 6319 automatic mechanical movement, the watch features a classic three-hand display with a practical day-date window at 3 o’clock.
The stainless-steel case has a compact, period-correct profile, while the original Seiko bracelet completes its vintage character. The case back identifies the watch as reference 6319-5021, with serial number 824993 indicating production in February of a year ending in 8, most likely February 1978 based on the documented production period of the 6319 movement.
Please note: the dial on this example is a redial. The original Seiko bracelet is retained.

Collector’s Note
The Seiko 5 collection has long been appreciated for combining automatic mechanical movements, practical day-date functionality and durable everyday construction. During the 1970s, Seiko produced a wide variety of case shapes and dial designs, including the distinctive cushion and TV-screen profiles seen on this example.
This watch is powered by the 21-jewel Seiko Caliber 6319, a 21,600 bph automatic movement from Seiko’s period of extensive mechanical watch production. The 6319-5021 reference identifies the movement and specific case configuration.
The serial number 824993 follows Seiko’s traditional serial-number format, indicating February of a year ending in 8. Given the known production era of the 6319 series, February 1978 is the most likely production date.
For collectors, the watch benefits from retaining its original Seiko bracelet, while the dial should be regarded as a redial rather than an original factory dial.

Case Back Details
The original case back carries the following markings:
* SEIKO
* 6319-5021
* 824993
* JAPAN A
* STAINLESS STEEL
* WATER RESISTANT
The 6319-5021 reference identifies the Caliber 6319 movement together with the specific case configuration.
The serial number 824993 can be read using Seiko’s traditional serial system:
* 8 — year ending in 8
* 2 — February
* 4993 — production sequence
Based on the 6319 movement’s production period, this points most likely to February 1978, although the serial itself does not independently establish the decade.
The original bracelet’s end links are marked Z101.

Movement Highlights
Powering the watch is Seiko’s Caliber 6319, a 21-jewel automatic mechanical movement operating at 21,600 vibrations per hour (3 Hz).
The self-winding movement is designed to wind through wrist movement and provides the traditional mechanical experience associated with vintage Seiko 5 watches.
Its combination of automatic winding, 21 jewels and practical day-date functionality made the 6319 family well suited to everyday wear during Seiko’s mechanical era.

Important Note
This is a vintage pre-owned timepiece. All specifications, including movement details, production date, dimensions, water resistance, bracelet configuration and other manufacturer information, are based on the watch, visible markings and available reference information and are provided for reference only.
Dial: The dial on this particular watch is a redial and is therefore not represented as the original factory-finished dial.
Bracelet: The watch retains its original Seiko stainless-steel bracelet, including the Z101-marked end links.
The serial number indicates February of a year ending in 8. Based on the known production period of the Caliber 6319, February 1978 is the most likely production date, but the serial number alone cannot conclusively establish the decade.
Due to age, previous use, servicing, replacement of components and service history, actual performance may vary. The original WATER RESISTANT marking should not be considered a guarantee of current water resistance. We recommend avoiding exposure to moisture unless the watch has been professionally pressure-tested.
Please review all photographs carefully, as they form an important part of the description and accurately represent the watch’s current cosmetic condition.
