It sounds like your watch has been magnetised. I had the same issue with a watch and bought a watch demagnetiser from eBay, followed the instructions and the watch now keeps great time. The demagnetiser costs about $15 so I'd say it's worth a try to fix the watch 👍

It's interesting when people focus on the history of the company when it comes to the Germans, how far back do we go? The brewery giant in England Greene King, has a very colourful history but no-one thinks of that when they are in their pubs. I recently bought the laco 42 as I didn't want an 18mm strap and love the watch, highly recommend no matter the history 👍
