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

For Seiko Collectors and Vintage fans, this is a highly sort after November 1968 Seiko 5 DX SUWA 6106-8180 25 Jewels Oversized Automatic Dress Watch in pristine condition. DX means Deluxe and this is confirmed with the number of jewels (25).

The silvery-white dial, 3D baton style silver indices, hands, day/date window and case are in immaculate condition after a thorough clean-up.

The case had also undergone a good cleaning and a good buff and is in near mint condition albeit a few minor scratches that are barely noticeable to the naked eye. The crystal has been replaced with an original Seiko crystal and is now spotless. The original glass will be provided with this watch upon purchase.

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 only in English.

The movement was carefully stripped and meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 30 June 2023 and another touch-up and calibration on 6 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 6106 movement, it has 25 jewels and operates at 21,600 beats an hour giving it an extremely high level of accuracy. The time-grapher, after 60 hours of calibration shows excellent readings i.e. rate of 0 seconds every 24 hours and amplitude of 203 with a straight 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 expert calibration.

The oversized case width and height are approximately 39mm (without crown), and 44mm respectively. The lug width is 18mm and the bracelet can accommodate wrists up to 20cm; thus, this watch is suitable for men and the modern women.

The bracelet is the original Seiko 5 signed SS bracelet that accompanied this timepiece. It too had undergone a thorough cleaning via ultrasonic immersion, tightening of links and a buff. It is now in near mint condition.

Due to its age, this timepiece has not been water-resistant tested.

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 a simple 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 / similar models in the market, BUT none are as well-kept and maintained as what you see here, and with an attractive price to boot. So, 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 November 1968! 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 cherished and well taken care of 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 full overhaul, an estimated S$ 80.00 to calibrate (depending on the condition of the watch), and S$ 100.00 to clean and 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 truly magnificent November 1968 Seiko 5 DX 6106-8180 SUWA in MINT condition with a beautifully preserved vintage dial, immaculate indices, case and movement; so, be unique and use something that is almost impossible to source.

This is a must-have for the Seiko die-hard fan, or any vintage watch fan for that matter!
