ETERNA Royal Quartz Kontiki

Eterna Royal Quartz KonTiki Ref. 729.1505.41 Quartz Cal. 940.111 · Black Fluted Dial · Integrated Steel Case · Circa 1970s The 1970s marked the golden age of quartz, when Swiss watchmaking was redefining precision through slimmer profiles, sharper case design, and a more modern sense of everyday luxury. The Eterna Royal Quartz KonTiki belongs to that moment beautifully, carrying the forward looking spirit of the era while coming from a manufacture with deep technical importance in Swiss watch history. Produced by Eterna, the historic watchmaking side closely tied to the origins of ETA, this reference represents far more than just period styling it reflects a serious moment of transition in horology. What makes this example especially compelling is its black fluted dial, paired with silver-coloured indices and a framed date display that give the watch a crisp, architectural character on the wrist. The integrated stainless steel case and bracelet design reinforce that distinctly 1970s aesthetic, while the dial texture adds depth without disturbing the overall restraint of the watch. It is a design that feels clean and confident, with just enough detail to reward a closer look. Measuring 36mm without crown and 38mm with crown, with a 43mm lug to lug and a slim 9mm profile, this Royal Quartz KonTiki wears with the balanced proportions that made these early quartz pieces so appealing. Inside beats the Quartz Calibre 940.111, a movement fitting for a model born during the most experimental and ambitious years of Swiss electronic watchmaking. Often regarded as one of the more interesting and less commonly seen Royal Quartz executions, this reference stands out as a thoughtful collector’s piece for those drawn to integrated design, early quartz history, and overlooked Swiss innovation.
