A BIRTHDAY WATCH IS A WATCH PRODUCED THE SAME MONTH AND YEAR AS YOUR BIRTH MONTH AND YEAR Type: Automatic Model: Gyro Marvel Year of Production: December 1959 Movement: 290 BPH: 18,000 Number of Jewels: 17 Hand and Dial: 3D Gold-Filled Baton Indices and Hands Width: 34.5mm Lug to Lug Height: 41.1mm Thickness: 12.0mm Lug Width: 18mm Bracelet: Brand-New Uber-Quality Genuine Reptile Red Leather Strap with Gold Buckle Pouch / Box: Brand-New EVA Type Zipper Pouch It was in 1956 that Seiko Seikosha debuted the Seiko Marvel (SUWA) which was Seiko's first ever built-in-house movement - Seiko used to build their watches using Swiss / English movements before this. The Seiko SUWA Marvel is a mechanical movement and is also Seiko's first watch with the second hand incorporated into the main movement. Prior to that, all Seiko watches were equipped with a mini second hand that was separate from the main movement. The Seiko SUWA Crown (Cal 560) would replace the Marvel in 1959. It was the same year (1956) that Seiko SUWA began upgrading the Marvel movement and incorporated the automatic winding, Diashock (anti-shock system) and the MAGIC LEVER*, and called this timepiece the Gyro Marvel. The movement number given is the Cal 290. Thus, this watch has the ability of mechanical and automatic winding which in truth, is a joy for watch enthusiasts. * The highly sensitive Magic lever utilises a "Claw Lever System" that allows bi-direction oscillation winding thus the watch is wound up faster and more efficiently. Most automatic watches have incorporated their version of the Magic Lever within their own movements soon after. Seiko SUWA officially launched the Gyro Marvel in 1959, and during those 3 odd years of production, the movement was upgraded from 17 to 19 to 21 jewels. This gorgeous December 1959 Seiko Gyro-Marvel, Model 290 is a 17 Jewel 14K Gold-Filled Automatic / Mechanical Watch, hence the world-famous Spinner located below the 12H Index. This is a breathtaking timepiece in so many ways that brought Seiko into the limelight as a serious watchmaking company that can now contend with the Swiss, English, German and American "big boys." For Seiko Collectors and Vintage fans, this may be one of the first ever Seiko Gyro Marvels to be produced in 1959. This December 1959 Vintage Seiko has a pearl white dial, gold indices and hands that were meticulously cleaned and are now in excellent condition. The crystal has been polished and is now in excellent condition as well albeit miniscule scratches do remain. The classical designed gold-filled case was also given a good cleaning and buffing to remove age marks, and miniscule hairline scratches. The crown is located at the traditional 3H positions and nicely tucked away to prevent damage or snags. The crown was reduced in size compared to the previous Seiko mechanical movements that require mechanical winding (hence the oversized crown). The movement was carefully stripped and meticulously cleaned via ultrasonic immersion, oiled, re-assembled and calibrated on 20 August 2026; hence, it underwent an overhaul and should be able to operate unhindered until the next servicing thereby giving the owner peace of mind. Equipped with Seiko SUWA's first ever automatic 290 movement, it has 17 Jewels and operate at 18,000 BPH. The time-grapher shows superb readings of +1 seconds and amplitude of 184 with a super straight consistent 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 expert calibration. 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. The watch comes with a brand-new uber-quality genuine reptile red leather strap with gold buckle as part of the deal. The case width and height are approx. 34.5mm (without crown) and 41.1mm respectively. The lug width is 18mm, and the strap can accommodate wrists up to 19cm; hence, suitable for men and the women. Due to its age, this timepiece has not been water-resistant tested. The pictures provided shows the watch in excellent 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 brand-new EVA pouch is provided. This rare watch will make a beautiful birthday present for that special someone, and its value will appreciate over time. This is a stunning Seiko Gyro Marvel; so, be unique and own a December 1959 Birthday Watch that is almost impossible to source in such fine condition or purchase it for that special someone instead.
