1967 · Quartz Wristwatch Movement · Work 794 of 1,871

A prototype quartz wristwatch of 1967 on a green linoleum bench in an observatory laboratory in Neuchâtel, its back upward under a magnifier lamp, a tonneau-shaped case of clear acrylic thirty-five millimetres wide on a black leather strap, through the clear back a silver-grey plate pierced with small holes, on it a round button cell under a brass clip, beside it a gold-coloured circuit sheet with a small black block and a hexagonal brass cap, a tiny gear train with red jewels in the centre, its front pressed against the bench, tweezers and rubber finger cots nearby, a white-gloved hand steadying the strap, north light from a tall window.
What the sources leave open: The claim that Beta 1 was the first quartz wristwatch comes from Frei himself and from a website run by his estate; the opposing side (Forrer and others) is not represented among the sources here.
