If you like the most posssible precision, the Model Railroad Chronograph can be certifed as a Chronometer – the most precise what you can carry as a mechanical wristwatch.

The certification is carried out exclusive from the C.S.O.C. (Controle Officiel of the Chronomètres), an indipendend association in Switzerland and is a rather costly process.

Only clockworks with minimal tolerences are selected and fine-adjusted. Then every watch has to go through a measuring program and runs in each case 24 hours in different positions and at different temperatures. After every cycle the deviation is read and may not cross on average ±8 seconds. The measuring cycles last a total of 14 days. Then the report is displayed to the numbered clock.

On account of the high expenses we certify the chronographs only on order. Delivery time on inquiry.
