According to most reliable online sources, Seiko introduced the 6106A and B movement in 1967. The 6106C was introduced in 1970 but do note that this "C" model comes in both 23J and 25J; hence, a significant price difference between both variations.

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 5 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.

For Seiko Collectors and Vintage fans, this is a Seiko 5 Actus SUWA 25J in excellent condition and is highly sort after due to its unique two tone maroon dial and 25J.

The two-tone reflective maroon dial, block style silver indices, day/date window and case are in immaculate condition after a good clean-up. The lumen hands show slight signs of age even after clean-up but they do faintly work.

This beautifully shaped ala Lord Matic silver case also underwent a good ultrasonic wash and rub while maintaining its super sexy curves. Most imperfections were removed without compromising the case shape. An original Seiko crystal was installed and polished.

The crown is located at its traditional 4H position and is nicely tucked away to prevent damage or snags yet easily accessible. The date quickset works as it should by pushing the crown in for adjustment.

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 22 August 2023. In short, it underwent an overhaul and  not a basic service. 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 6106C movement, it has an impressive 25 Jewels that operate at 21,600 beats per hour (BPH) giving it excellent accuracy and longevity. The time-grapher, after 60 hours of calibration, shows very impressive readings i.e. rate of +3 seconds every 24 hours and amplitude of 156 with a straight 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, 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 37mm (without crown) and 40.5mm respectively. The lug width 18mm and the bracelet can accommodate wrists up to 21cm; hence, this watch is suitable for men and the modern women.

The SS bracelet is an original Seiko 5 Actus signed SS bracelet. It too was given a good ultrasonic wash and 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, this timepiece has not been water-resistant tested due to its age.

The pictures provided show the watch’s case in near mint 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 and 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 someone special born in September 1973! Another no-brainer is the fact that the value of this watch will appreciate over time.

This is a highly sort-after Collectors Seiko 5 Actus 25J two-tone maroon black dial 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!
