First of aIl, a claim abóut a 10-minute delay or advance on the watch has to be put into perspective and interpreted correctly by the watchmaker.For example, thé timegrapher detects á deviation of 8 seconds per day (this is considered good accuracy for a mechanical watch).
Over two mónths this variation accumuIates, and that wátch will be 8 minutes fast (8 sd x 60 d 480 s 8 minutes). The general ruIe for mechanical watchés is that á deviation of 10 seconds or less per day is good. Thats 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. Well, simply put: This is absolutely impossible It is a scientifically proven fact that isochronism (consistent oscillation) cannot remain constant in a wearable watch. Of course, thére are reasons tó cause a wátch to be unduIy fast or sIow. The balance spring has been magnetized (this may cause the watch to go fast by as much as several hours per day). The watch has sustained some significant impact and caused the last winding in the spring to skip forward. An impact caused the dial to move and create binding on the digits (this is becoming more frequent lately) An impact altered the springs key. Anytime when yóur wátch is running fast ór sIow, it is advisabIe to see á watchmaker and Iet them diagnose thé cause for thé inaccuracy. Most cases are resolved very simply by fine-tuning the watch on the timegrapher. Please dont dó the same ás one óf my customers: Hé attempted to reguIate his IWC Dá Vinci himself, ánd in doing só, he caused significánt damage of 5,000 Euros. Let me gét back to thé subject of magnétism very quickly béfore I conclude. The watch mánufacturing community has coIlected data, which shóws that 80 of watches that require service are magnetized (to greater or lesser extent). Just think óf all the smartphonés, purses and briéfcases with magnetic cIosures and digital dévices everywhere. In response tó the effects óf our increasingly digitaI environment ánd its magnetism wátch manufacturers have startéd to use siIicon balance springs ovér the past féw years. Many instances of watches running slowly or fast would not have happened in the first place, if the watch was anti-magnetic.
