For sale we have a vintage Eterna Royal Quartz Kontiki, circa 1977. Made during the golden age of quartz by Eterna who were the watchmaking side of the company while ETA was created by Eterna as the movement-making company, making this basically a totally in-house Swiss-made watch. When this released it was the thinnest quartz watch in the world at 9.3mm. It is rumoured that only 1000 Royal Quartz Kontiki were made each numbered on the case back (in this case this is number 868/1000) with the first example being gifted to Dr Rudolf Schild-Comtesse, who was managing director of ETA and laid the foundation for the Swatch Group to come. The Royal Quartz has several interesting features including a screw-down crown (to help with the then-water resistance of 100m), a hidden invisible clasp, anti-reflective scratch-resistant sapphire glass and a design very similar to Gerald Genta designed AP Royal Oak/Patek Philippe Nautilus with the blue-grey pin stripe dial, octagonal crown and integrated bracelet although the designer is not confirmed to be by him. The design also pre-dates the original Tissot that the Tissot PRX is said to be inspired by (and Tissot mainly use ETA movements as they are both owned by Swatch Group) despite sharing suspiciously similar design cues. The feel of the Royal Quartz is undeniably luxurious to the touch with astonishing fit and finishing (even the print of the date wheel is so crisp compared to many other big brands) - many collectors say that the Royal Quartz is far higher quality than Omega's quartz offerings of the time. The bracelet is a multilink affair for maximum comfort and with screw-in links for ease of use and quality. Condition is amazing for its age with minimal wear (although small general wear is expected), no refinishing. There is a slight purple hue in the middle of the crystal in some light which I assume is something to do with the anti-reflective coating over time. Although the lume is not as luminescent as it once was, it has turned into a very nice patina. The dial in some light is a navy blue while in other light it looks like a suit grey. The brushing surfaces and polished chamfers are in very good condition. The bezel is very unique and is possibly the best part of the design.  Dimensions are:35.6mm x 44mm x 9.1mm Looking for $750 (Buyer pays Paypal fees on top) International Tracked Shipping included in price More pics: [https://flic.kr/s/aHBqjC4eF9](https://flic.kr/s/aHBqjC4eF9) Can accommodate a wrist size of up to 18cm.
