According to most reliable online sources, the Seiko 6206 movement made its debut in 1963. This movement was an improved version of the Caliber 400 (later 410) movement. In between these 2 movements were the 6201 and 6220. The 6201 was used in the first Seiko 5 Seikomatic but it was the 6206 that laid the groundwork for the 62xx series that brought forth the Grand Seiko to the world.

The 6206 movement is found in Seikomatics and Weekdaters, and is highly sought after because it is not only a thing of beauty, but its components were cannibalised for many more expensive watches, thereby this particular 6206-8080 with white-gold filled indices and hands is highly sought after due to its scarcity.

For Seiko Collectors and Vintage fans, this is a Seiko SUWA Seikosha Dolphin series in near mint. The dolphin was used to impress its higher waterproofing capabilities of 30m; hence, it was used by many for shallow diving instead of the typical diver's watch that coincidentally uses the 62xx movement as well when first introduced!

This extremely rare Seiko Seikomatic Two Window is a sight to behold! Its original silver dial, reflective chapter ring, 3D white-gold-filled baton indices, logo, hands, date/day window, case and silver case-back are also in pristine condition after a thorough clean-up. The original crystal was polished and is now in excellent condition albeit miniscule scratches do remain. The timeless masculine cylindrical shaped case had undergone a proper cleaning and was buffed as best as possible; however, there are some hairline scratches still present.

The crown is located at the traditional 4H position and is nicely tucked away to prevent damage or snags. Its movement was carefully stripped and meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 17 August 2026; hence it underwent an overhaul and not a general servicing. It should be able to operate unhindered until the next servicing thereby providing the owner peace of mind.

Equipped with the well revered 6206 movement, it has 26 Jewels that operate at 18,000 BPH. The time-grapher shows excellent readings of 0 seconds and amplitude of 183! Such readings are truly exceptional even by brand new modern automatic watch standards whereby the accepted tolerance is -20 to +40 seconds a day!

The case width and height are approximately 36.9mm (without crown) and 44.0mm respectively. The lug width is 19mm and the bracelet can accommodate wrists up to 17.3cm. A vintage Bambi bracelet accompanies this watch as part of the deal. Take note that Seiko only produced their own signed bracelets in 1968; so, Bambi and Maruman bracelets accompanied these earlier watches.

This is a truly magnificent August 1965 Seiko Seikomatic SUWA Two Window watch in near-mint condition with a beautifully preserved vintage dial, immaculate white-gold-filled indices, hands, and case, clean movement, case and vintage SS Bambi bracelet; so, be unique and own an August 1965 Birthday Watch that is almost impossible to source in such fine condition or purchase it for that special someone instead.
