I’m one of those people who wears a watch at night. I thought I’d give this 165.003 a run out, not having worn it much it very much since I had it serviced a year or so ago.
Finding it had gained about thirty minutes over a four hour period (twice) I’ve now watched a couple of YouTube videos, downloaded the Lipsi app onto my iPhone and after a positive? negative? result, have now ordered a demagnetiser from eBay.
So, back in the box until it’s demagnetised and this Longines was handy …..
