Accuracy of automatic watches

By their very nature, mechanical watches are prone to a certain degree of inaccuracy. The complex interplay between the tiny components, the individual habits of the wearer, and indeed other external influences are responsible for the fact that the displayed time is constantly subject to certain variations. Generally speaking, care is taken when adjusting the watch in the first place to ensure that the movement will never run too slowly, even under unfavourable conditions, but instead is more likely to run slightly fast.

As supplied by the manufacturer, the ETA movement 2824-2 we use in our watches runs fast by 0 to 40 seconds per day. Our manufacturer's master watchmaker in Pforzheim then manually adjusts the movements to achieve a much lower degree of inaccuracy of between 0 and, at most, 15 seconds. This corresponds to the precision level demanded by manufacturers for automatic watches in the upper price bracket.

Lovers of mechanical movements should learn to live with a certain degree of inaccuracy. Anyone who attaches great importance to absolute precision and a time display which is accurate to the second should opt for our quartz models which achieve a comparatively negligible deviation of just -10/+20 seconds per month.
