This series is characterised by pure simplicity, without complications. The white, silver-plated dial, with its comforting appearance, highlights the blue steel hands. This simplicity reduces this model to the essence of the Chronograaf. The ZD serial number means 'zonder datum', i.e. without a date. Limited edition of 888.
