According to most reliable online sources, the Seiko 6218 movement made its debut in 1964. The 6218 is an improved version of the 6206 and many consider this movement as a forerunner to the GS6245 and GS6246 that were launched in 1966.

The 6218 movement is found in Seikomatic's and is highly sort after because it resembles the Seiko Chronometer GS6246 and it also has a higher number of jewels (35) and BHP (36,000) compared to previously launched Seiko models, and also due to its scarcity.

For Seiko Collectors and Vintage fans, this is a Seiko SUWA Seikosha Dolphin series. The dolphin was used to impress its higher waterproofing capabilities; 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 Seikomatic is the holy grail because its model and case number (6218-8950) tally's with the dial and case-back which is extremely rare!

This extremely rare Seiko Seikomatic's original silvery-white dial, reflective chapter ring, 3D gold-filled baton indices, logo, hands, date/day window, case and silver case-back are in pristine condition after a thorough clean-up. The crystal was buffed albeit miniscule scratches do remain but are barely noticeable.

The masculine shaped gold-filled case had undergone a proper cleaning, and was buffed as best as possible; however, there are some hairline scratches present.

The crown is located at the traditional 4H position and is nicely tucked away to prevent damage or snags. The date and time quickset is via the traditional method of pulling out the crown to the first and second level for date and time adjustment respectively. The day quickset is via turning the hands forwards and backwards past midnight. Another unique feature is the day is only in English.

Its movement was carefully stripped and meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 4 July 2024; hence it underwent an overhaul and should be able to operate unhindered until the next servicing thereby providing the owner peace of mind.

Equipped with the well revered 6218 movement, it has 35 Jewels and operate at 18,000 BPH. The time-grapher, after hours of calibration, shows excellent readings of an average rate of +1 seconds every 24 hours and amplitude of 239 with super straight centered line! Such readings are exceptional even by brand new modern automatic watch standards whereby the accepted tolerance is -20 to +40 seconds a day! This is a testament to the quality, the meticulous care provided over the years, and the painstaking expert calibration.

The case width and height are approx. 37mm (w/o crown) and 42mm respectively. The lug width is 19mm and the strap can accommodate wrists up to 21cm; hence, suitable for men and the modern women.

A brand new beautifully crafted high quality hand-stitched genuine suede leather strap with matching stitching is provided.

To the best of our knowledge while overhauling this timepiece, the watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket or modified parts.

Due to its age, this timepiece has not been water-resistant tested even though the seals are in place.

The pictures provided shows the watch in pristine condition (no dents, dings and major scratches), and the movement within squeaky clean and well maintained. It has also been demagnetised to improve parts reliability, minimise wear + tear, and improve accuracy. The only drawback is the lack of documentation and original box. A brand new EVA pouch is provided.

This extremely rare timepiece will make a beautiful birthday present for that special someone born in June 1965, and its value will appreciate over time.

Bear in mind that this watch has seen many of the previous owners’ ups and downs in life, and should be cherished and well taken care of for the next generation to savour such engineering beauty.

This is a truly magnificent June 1965 Seiko Seikomatic Weekdater SUWA watch in near-mint condition; so, be unique and own a watch that is almost impossible to source in such fine condition.
