Seiko's 1960s-era "Weekdater" line offered some of the most Bauhaus-like designs to come out of the time period, and echoes much of the minimalism Seiko brought forth in the years following.  And at the forefront of this line was the J13080 – like the one here from the mid-1960s – and unlike the Citizen 8110 bullhead which adorned the wrist of Brad Pitt’s character in Tarantino's “Once Upon a Time…in Hollywood,” the J13080 existed when the movie was set, in 1969.


The J13080’s movement, the 400 (produced between July 1963 and February 1965), is an automatic that evolved into the 6206 in 1964.  However, the 6206 was “down jeweled” from the 400’s 33 jewels to 26, to make it easier to produce.  The 6206 went on to be one of the best-known Seiko movements, cased in numerous Seiko designs of the 1960s – to include the famed Seiko 6218 Weekdater.

The J13080’s dial features the applied “Seikomatic” spinning top badge at the 12 o’clock position, and at the six o’clock marker the AD “Star” insignia signifies an appliqué dial.  The J13080, like the 6206 after it, featured Seiko’s well-known dolphin insignia (signifying water resistance), but the etched caseback was unfortunately quite prone to wear.  Finally, the case size is perfect for most individuals, and it features a tiny “hidden” recessed crown at four o’clock and a wide flat bezel, with nice fat lugs.

This J13080 comes with a leather rally strap, nylon NATO strap, Pelican travel case, and springbar tool.

1964 Seiko J13080 Seikomatic “Weekdater” Automatic

  • DIAL: Original silver starburst dial, with original dauphin minute, hour, and second hands. Date and day function at 3 and 9 o'clock positions work as designed. At over five decades old, the dial has only minor blemishes near the 12 o’clock position, and features a beautiful radial brushed finish, and a slightly depressed outer track ring that lends some depth to the overall look.  Please note a subtle raised dent in the dial near the 9 o'clock position.


    CASE: Original 37mm x 43.5mm stainless steel case, with original caseback; please note that although the caseback has wear – common in these models – the famous Seiko dolphin is still evident in correct light.


    CRYSTAL: Original acrylic Seiko crystal, with no blemishes or scratches – however, there is a small crack on the side of the crystal (so not noticeable from straight on) at the nine o’clock position.


    BAND: New 19mm dark brown leather rally strap, with black accent stitching.  This J13080 also comes with a 19mm nylon NATO strap, replete with stainless steel hardware – a great complement to the sporty nature of this Seikomatic automatic.


    MOVEMENT: Original Seiko 33-jewel 400 automatic movement, manufactured in 1964.


    CROWN: Original recessed unsigned stainless-steel crown.
