Chronometer Watches

A chronometer is a watch whose movement has been tested for accuracy by an independent body such as the Swiss COSC. Here you will find certified models from various manufacturers, from sporty diver's watches and pilot's chronographs to classic everyday watches. New watches are unworn and come with box, papers and manufacturer's warranty, while inspected Certified Pre-Owned models are labelled as such. Shipping is fully insured and the delivery time is shown on every watch.

How a chronometer is tested

The term chronometer is protected and requires passing a test by an independent body – in Switzerland usually the COSC. Testing takes place over 15 days in five positions and at three temperatures. The limit is an average daily rate deviation of minus four to plus six seconds; movements that do not meet this tolerance may not bear the designation.

In-house standards beyond the COSC norm

Several manufactures also apply their own, stricter standards and test the fully assembled watch rather than just the uncased movement. Rolex, for example, specifies minus two to plus two seconds per day for its models, while Omega tests according to the Master Chronometer standard, including exposure to magnetic fields. Such certificates say a great deal about a manufacture's production effort and play an important role in the later valuation of a watch.
