I have a MN22 FXD which I’ve owned from new. Poor strap longevity aside, I love the watch - the design, comfort and military association all add up to a cool timepiece.

I’ve worn mine as part of a rotation for over a year now and it spends a fair bit of time on a winder. Timekeeping was very accurate for the first few months - it would lose about 5s a week which is impressive.

Over the past few months I’ve noticed the timekeeping slipping significantly - it’s now losing 7-8s per day - not anything to cry about, but out of spec and poor for this movement. It also takes a lot of shaking to get going once the PR has been drained and doesn’t seem to respond particularly to manual winding.

Is this normal for a MT5602 movement or do I have a bad one? Has anyone else experienced poor performance from their FXDs?
