Vintage Seiko 5 Automatic 6309-7270 | Sunburst Blue Dial, Retro Tonneau Case

This is a stunning vintage Seiko 5 Automatic featuring a vibrant and eye-catching blue sunburst dial. The dial has a distinct striped or brushed horizontal pattern, which shifts beautifully in the light, giving it a true 1970s retro appeal. The watch is housed in a classic Tonneau-shaped stainless steel case, a popular design in its era. The case has an approximate size of 37mm. The dial features applied baton hour markers and an easily legible day/date complication at the 3 o'clock position. The timepiece is powered by a reliable Seiko automatic movement, which can be identified by the movement/case code 6309-7270 etched on the stainless steel caseback. This classic 6309 caliber is a workhorse known for its durability. The movement can also be seen through the open case during servicing or repair, as shown in the movement photo. It comes fitted on a black leather strap, complementing the retro aesthetic of the case and dial.
