I have been hearing people saying their 2500 movements are getting magnetized at airports. Anyone have this happen too? Or in other ways?
Kind of a weird blanket statement. Hasn't happened to me in the ownership of three different 2500-based Seamasters, and plenty of flights between.
If a problem watch comes my way for correction, being magnetized is the very last problem I look for. Unless it is a very old watch. Then very often, it is the first thing I look for. I maybe use my demagnetizer 4 or 5 times per year, and then almost always to magnetize a screw driver. Comes in handy for clockmwork.
Not really a known issue for the 2500. It doesn't have a silicon balance spring, but an Anachron alloy spring from Nivarox, so it would be as susceptible to magnetism as most other modern watches. Note that in a modern servicing environment, watch movements are always demagnetized during service. I demagnetize before cleaning, and also after reassembly and before final timing adjustments - this is common practice in any service center or modern shop. Cheers, Al
