SJX: Introducing the Neuchâtel Observatory Chronometer Database

SJX: Introducing the Neuchâtel Observatory Chronometer Database. “Put together by Dr Christian Müller, the Observatory Chronometer Database (OCD) is a comprehensive compilation of all 3356 wristwatch movements ever submitted to the Neuchâtel Observatory for testing between the years 1945 to 1967 – the golden age of mechanical wristwatch chronometry. Then known as the Observatoire Astronomique et Chronometrique de Neuchatel, as it was described on historical chronometer certificates, the Neuchâtel Observatory conducted annual contests for various classes of timekeepers, from pocket watches to wristwatches, both mechanical and quartz (the OCD only covers mechanical wristwatches).”
