: Since this had generated interest and questions
: here before, I thought I'd post some
: findings about my SMP and magnetism.
: After my watch started loosing more than 8
: secs/day I found that it deflected a compass
: needle and was therefore magnetized. At the
: time no-one answered my question " did
: an otherwise accurate SMP deflect a compass?
: ". Having got mine serviced, I can now
: say it doesn't - at all.
: However, I'm still unsure what's required to
: demagnetize a mechanical watch. Some say the
: back needs to be removed, others don't. When
: you're dealing with a dive watch with seals
: this is an important factor. Please post if
: you know about this process. Also what a
: good watchmaker would charge.
: Also, mine was demagnetized under warranty, at
: least the authorized dealer's 1-year
: extended warranty - it had been mentioned
: here before that it should not be covered
: since it is not a fault of the watch design
: or manufacturing. Thankfully the dealer just
: received a quote back from Swatch saying it
: would be C$440 to fix, without it mentioning
: what was needed or what caused it. I guess I
: may have just been lucky (for once Swatch's
: substandard service practices worked in my
: benefit!) Let's hear your experiences.
Demagnitizing a watch is an extremely simple process. All you need is a simple device that alternates between North and South and keeps doing that really fast and all you need to do is to start near the watch and then pull it away from the watch slowly. This will neurtalize the field. Taking the back and iron ore off from the back will only speed up this process.
