Please don’t do the same as one of my customers: He attempted to regulate his IWC Da Vinci himself, and in doing so, he caused significant damage of 5,000 Euros. Depending on the watch and your location the cost runs somewhere between EUR 20 and 50. Most cases are resolved very simply by fine-tuning the watch on the timegrapher. An impact caused the dial to move and create binding on the digits (this is becoming more frequent lately)Īnytime when your watch is running fast or slow, it is advisable to see a watchmaker and let them diagnose the cause for the inaccuracy.The movement needs to be professionally serviced.An impact on the watch altered the spring’s key.The watch has sustained some significant impact and caused the last winding in the spring to skip forward.The balance spring has been magnetized (this may cause the watch to go fast by as much as several hours per day).The movement requires professional service.Of course, there are reasons to cause a watch to be unduly fast or slow.Ī few of the reasons why a watch may be fast: Well, simply put: This is absolutely impossible! It is a scientifically proven fact that isochronism (consistent oscillation) cannot remain constant in a wearable watch. That’s when my customers usually disagree: „But my neighbor tells me that his Rolex has been 100% accurate for five years with no time deviations ever”.

The general rule for mechanical watches is that a deviation of 10 seconds or less per day is good. Over two months this variation accumulates, and that watch will be 8 minutes fast (8 s/d x 60 d = 480 s = 8 minutes). For example, the timegrapher detects a deviation of +8 seconds per day (this is considered good accuracy for a mechanical watch). First of all, a claim about a 10-minute delay or advance on the watch has to be put into perspective and interpreted correctly by the watchmaker. Is your watch gaining or losing time every day? Very often when a customer comes to us, the reason is an inaccurate running of their watch.
