The C70 DBR1 COSC, with its new movement is accurate to within one second a month and has been certified by the Contrôle Officiel Suisse des Chronomètres (COSC). It is available in a limited edition run of only 200 pieces.
A bit about the new upgraded ETA 251.232 quartz movement. The new movement spots an additional 4th chronograph hand that is centrally mounted and it measures minutes. This configuration then allows the chronograph eyes to measure hours, minutes and tenths of seconds.
This watch will launch in October 2011 at a price of just £575 replacing the original C70 DBR1, which sold out in record time. I suspect this version will also be a run away success.
