Demagnetising

[baradona]

Hi

My 116520 Daytona appears to be magnetised - it runs a bit fast, and both moves the needle of a compass (though only a very few degrees), and comes up as magnetised on the Lepsi app.

Given current conditions, I'm not going to be able to get it to a watch shop, so I plan to buy a cheap generic demagnetiser from Amazon.

My question is this. In all of the videos I've watched the watch is demagnetised by placing the watch case-back to the demagnetiser and lifting it away. I don't have a springbar tool, and don't want to remove the bracelet because I am concerned that I will drop a springier and damage the watch case. Is there any reason not to demagnetise the watch dial side down?

Thanks
