These production watches were accurate to 5 seconds per month, far better than any automatic or manual wind chronometer at the time and an enormous leap in accurate time keeping. The movement was a modular design and components were manufactured by individual companies (such as Omega who made the micro motor) and then assembled at three workshops.
