According to most legitimate online information available, the Seiko 6309 movement made its debut in 1976 and lasted until 1988.

This movement was extremely successful and was used in numerous vintage models including this famous 6309-7290 4th generation diver's watch that became affectionately known as the "Turtle."

For Seiko Collectors and Vintage fans, this is a Made in Japan Seiko 6309-7290 Turtle SUWA in superb condition.

This classic 6309-7290 Automatic has a well preserved matt black dial and date/day window that underwent a good clean-up thus revealing minimal signs of aging. The hands show signs of aging yet the hand lumens are operable!

The classic cylindrical shaped silver case was buffed as best as possible; however, there are some hairline scratches present. The original mineral glass was replaced with an aftermarket glass. The original glass will accompany the timepiece as part of the sale.

The bi-directional Bezel and Insert underwent a good clean up and is moving smoothly yet firmly.

The crown is located at its traditional 4H position and tucked away nicely between crown guards located north and south of the crown to prevent damage or snags, yet easily accessible.

The Hands and Day/Date adjustments are via the traditional method of pulling the uncorked crown to the first and second level for date and time adjustment respectively.

The Day is in English and Roman Numerals, cool!

The movement was carefully stripped and meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 16 February 2024; 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 a peace of mind.

Equipped with the famous 6309 workhorse movement, it has 17 jewels and operate at 21,600 beats an hour giving it uncanny accuracy! The time-grapher, after 60 hours of calibration, shows excellent readings i.e. rate of -2 seconds every 24 hours and amplitude of 143 with a relatively straight centered line! Such readings are truly exceptional even by brand new modern automatic watch standards! This is a testament to the quality, excellent power reserve and longevity for such a vintage timepiece, the meticulous care provided over the years, and of course the painstaking expert calibration conducted.

The case width and height are approximately 43.5mm and 43mm respectively. The lug width is 22mm and the strap can accommodate wrists up to 21cm; hence, suitable for men and the modern women.

All seals and gaskets have been serviced/replaced. However, due to its age, this timepiece has not been water-resistant tested.

A brand new OEM Seiko Wave Strap is provided, and is extremely comfortable to wear. The Buyer has the option to choose a different design and colour silicon strap from my array of straps should he / she wishes to do so.

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 parts or modified.

The pictures provided shows the watch case in immaculate condition (no dents 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, so an aftermarket box / pouch will be provided instead.

Seldom can one find a vintage watch that offers this and more. Yes, there are many other same models in the market, BUT none are as well kept and maintained as what you see here, and with an attractive price to boot. Hence, it is a no-brainer that this one-of-a-kind watch will make an extremely beautiful birthday present for that special someone born in September 1985. Another no-brainer is the fact that the value of this watch 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 cared and cherished for the next generation to savour such engineering beauty.

Do also bear in mind that it will cost between S$ 180.00 to S$ 200.00 for a proper overhaul, an estimated S$ 80.00 to calibrate, and S$ 80.00 to clean and polish the entire watch - these costs do not apply when purchasing this timepiece. So, if anyone was to sell such a timepiece at a low price yet claim that it has been serviced, one has to ask what kind of servicing was conducted, if any.

This is a highly sort-after Made in Japan Seiko Turtle 6309-7290 Diver's; so, be unique and use something that is almost impossible to source.

This is a must-have for the Seiko die-hard fan or a serious watch collector!
