According to most reliable online sources, the Seiko 6306 movement made its debut in 1976 to 1981, and is the predecessor of the famous 6309 movement.

As most Seiko die-hard fans know, the Seiko Actus was manufactured and assembled in Japan and solely meant for the Japanese Domestic Market (JDM).

The Seiko Actus was manufactured in both SUWA and DAINI factories because both factories competed against one another (think Apple and Macintosh) that brought out the best designs and movements during that era. Thus, the value of each vintage watch is determined by the movement within. So, the buyer must exercise due diligence when purchasing a Seiko Actus, Seiko 5 Actus etc. and which movement calibers they are using because the value is determined by this important factor.

For Seiko Collectors and Vintage fans, this is a Seiko Actus JDM SUWA 21J in near mint condition and is highly sort after due to its unique dial and its design scarcity.

The patterned milk white dial, 3D baton silver indices, day/date window, hands and case are in immaculate condition and been given a deep cleaning to bring out the true beauty hidden.

This beautifully squarish shaped silver case also underwent ultrasonic immersion and a good rub while maintaining its super sexy curves and lines. Most imperfections were removed without compromising the case shape. The crystal is original and was also given a good polish.

The crown is original and is located at the 3H position and is nicely tucked away yet easily accessible. The date / day and time quickset works flawlessly by pulling out the crown to the first and second level for relevant adjustments.

Because it is a JDM, the day is in English and Kanji - cool!

The movement was carefully stripped and meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 25 August 2023; hence it underwent an overhaul and not a general servicing. It should be able to operate unhindered for the next 5 to 10 years at the very least thereby providing the owner peace of mind.

Equipped with the 6306A movement, it has 21 Jewels that operate at 21,600 beats per hour (BPH) giving it excellent accuracy and longevity. The time-grapher, after 60 odd hours of calibration, shows very impressive readings i.e. rate of 0 seconds every 24 hours and amplitude of 177 with a relatively straight and centered line! Such readings are truly 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, excellent power reserve and longevity for such a vintage timepiece, the meticulous care provided over the years, and of course the painstaking calibration conducted.

The case width and height are approximately 35mm (without crown) and 40.5mm respectively. The lug to lug is 19mm and the bracelet can accommodate wrists up to 20cm; hence, this watch is suitable for men and the modern women.

The SS bracelet is original Seiko Actus signed and also underwent ultrasonic cleaning and a good rub and is now in excellent condition.

To the best of our knowledge and expertise when overhauling the timepiece, the watch is 100% original Seiko components from this particular watch. No parts were replaced with aftermarket parts or modified thereby it is considered in near MINT condition.

Even though the seals and gaskets are present / replaced, this timepiece has not been water-resistant tested due to its age.

The pictures provided show the watch’s case in near perfect condition 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 nice purposeful carrying case or box will be provided instead.

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.

Yes, there are many other same models in the market, BUT almost all are not in the same quality condition or is well maintained as what you see here. Hence, it is a no-brainer that this one-of-a-kind timepiece will make an extremely beautiful birthday present for that special someone born in September 1976! Another no-brainer is the fact that the value of this watch will appreciate over time.


Do also bear in mind that it will cost between S$ 180.00 to S$ 200.00 for an overhaul, an estimated S$ 80.00 to calibrate (depending on watch condition), and S$ 100.00 to polish including tightening of bracelet links - 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 Collectors Seiko Actus 6306-5000 patterned milky white dial with original bracelet in stunning condition; so, be unique and wear something that is almost impossible to source.

This is a must-have for the Seiko die-hard fan, and in fact, any serious watch collector!
