IWC Pilot’s Watch Losing Time Consistently – Need Advice on Possible Causes

Hi IWC Community,

I 've had my IWC Pilot's Watch Mark XVIII for about a year, and recently I've noticed that it's been losing time consistently--about a few minutes each week. I wear it daily, so it should be staying wound, and I haven't had any issues like this before.

Here 's what I'm wondering:

• Could environmental factors like temperature or magnetic exposure cause this type of time loss?
• Is this a sign it needs a maintenance service, or should I consider a full regulation?
• Has anyone else had a similar experience with an automatic IWC watch?

Any advice would be greatly appreciated! I 'd love to understand the possible causes before I send it in for service. Moreover, if you are into capcut video editing and looking to download CapCut pro from a trusted source then click here. Thanks in advance!

Easy to first check if it has been magnetised. Lots of free apps for your phone can diagnose that for you- and if so, that is an easy and cheap fix.

A watch that has been magnetized will generally run fast rather than slow. A watch running slow is more likely to have debris or dried oils slowing it down, but there are other possibilities as well. As Remi mentioned, there are some apps you can use to make some assessments. These apps can provide information such as rate, beat error and amplitude.

I like an app called "Watch Accuracy Meter" that is able to produce good results quickly. However, it wll not diagnose the cause of a slow rate or beat error. You will need a watchmaker to really address the issue. Fortunately, your watch has a movement that alomost any qualified watchmaker should be able to service.

If you want to check if your watch is magnetized, just hold a compass directly over it and see if the needle changes direction when the compass is next to the watch.
