●Product Description
[1960s, Overhauled]
This is an early model (Ref. J15019) of the Skyliner Calendar, which carries on the lineage of Seiko's slim dress watches.

Although it was introduced as a more affordable version of the high-end Liner at the time, it is equipped with a high-end 21-jewel movement.
Its slim form, with unnecessary thickness shaved off, and the three-dimensional, beautiful indices on the AD dial (14K gold filled) symbolize the Japanese aesthetic of the era.

The case back retains the Skyliner script, and the 14K gold-filled case adds a touch of glamour to your wrist. This is a timepiece befitting an adult vintage style, suitable for everything from business to formal occasions.

(This may vary depending on posture, etc.)
・Exterior: As this is a vintage item over half a century old, there are age-appropriate scuffs and minor scratches on the case and crystal, and slight fading around the edge of the dial. However, these do not detract from its antique charm.
・Strap: Equipped with a lizard leather strap (burgundy). It shows signs of use but is still wearable.
・Functionality: The manual winding feels smooth, and the calendar changes over correctly.
