According to the most legitimate information online, Seiko introduced the 6106 movement in 1967.

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 within and the number of jewels because the value is determined by these important factors.

For Seiko Collectors and Vintage fans, this is an April 1972 Seiko 5 Actus JDM SUWA 23J in stunning condition.

The silvery sunburst dial, 3D silver baton indices, day/date window, baton hands and case are in near mint after a deep cleaning to bring out the true hidden beauty.

This hour-glass shaped silver case with built-in lugs underwent ultrasonic immersion and a good rub while maintaining its super sexy curves and lines. Most imperfections were removed without compromising the case shape albeit some miniscule scratches remain. The crystal was given a good clean-up and buff and is now in excellent condition albeit miniscule scratches do remain.

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.

Because it is 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 May 2024. It should be able to operate unhindered until the next servicing thereby providing the owner peace of mind.

Equipped with the 6106 movement, it has 23 Jewels that operate at 21,600 BPH. The time-grapher, after hours of calibration, shows very impressive readings of 0 seconds every 24 hours and amplitude of 122 with a relatively straight and 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 calibration conducted.

The case width and height are approximately 37.4mm (w/o crown) and 41mm respectively. The lug width is 19mm, and the bracelet can accommodate wrists up to 17.2cm; hence, suitable for men and the modern women.

The SS bracelet is a Marumen brand hi-quality vintage model. It too was cleaned via ultrasonic immersion and given a good polish afterwards and is now in excellent condition albeit miniscule scratches on the buckle.

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 or modified parts.

Even though the case seal was replaced, this timepiece has not been water-resistant tested due to its age.

The pictures provided shows the watch 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 brand new EVA pouch is 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.

This timepiece will make a beautiful birthday present for that special someone born in April 1972, and its value will appreciate!

This is a beautiful April 1972 Seiko 5 Actus 6106-7520 case in stunning condition; so, be unique and wear something that is almost impossible to source in such fine condition.
