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.
The Seiko Silverwave was designed as a sports / sports diving watch in mind because of the cessation of the Seikomatic and Sportsman in the early 70s; hence it is a swimmers' watch but not full fledged divers watch. Notice its 4H crown location ala diver's watch style.
For Seiko Collectors and Vintage fans, THIS IS A SEIKO 6306-8000 Silverwave JDM model in stunning condition and IS A HIGHLY SORT AFTER COLLECTORS WATCH for a variety of reasons.
It's original silvery-white dial, 3D baton indices, hands, date window and case are in excellent condition after a deep clean-up. The case and original crystal were buffed to remove age marks and stains and is now in stunning condition albeit a few minor scratches that are barely noticeable to the naked eye.
The crown is original and is located at its traditional 4H position.
This beautifully preserved watch was carefully stripped and every part meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 26 August 2023. 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 workhorse 6306 movement, it operates at 21,600 BHP and has 21 jewels that provides outstanding accuracy. The time-grapher, after 60 hours of calibration, shows excellent readings i.e. rate of -2 seconds every 24 hours and amplitude of 187 with a straight center line! Such readings are extremely 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, the meticulous care provided over the years, and the expert calibration conducted for such a vintage timepiece.
The case width (without crown) and height are approximately 38mm and 43mm respectively. This lug width is 20mm and the strap can accommodate wrists up to 21cm; hence, this watch is suitable for men and the modern women.
A beautiful hi-quality carbon-fibre heavy duty strap with greenish stitching is provided to enhance the colour of the case and dial.
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.
Due to its age, this timepiece has not been water-resistant tested.
The pictures provided show the watch’s 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. A nice purposeful carrying case or box 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, maintained and calibrated 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 August 1978. 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.
This is a highly sort-after Seiko Silverwave 6306-8000 in stunning condition with a stunningly preserved dial, indices, hands and case, and a high quality carbon-fibre strap, 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!
