Basically, the fabric of the strap constantly rubs up against the case back, and when dirt gets trapped in between, over time, that causes scratches and even marring on the case back. According to a dedicated article by British GQ, this kind of marring cannot be prevented by simply cleaning the strap. They say no matter what, the fabric will cause wear to the case back. Are they right?
Here is a Seamaster that has spent most of the last 4 years on nato or MN straps.
I wouldn’t be too worried.
Holy crap that’s pristine. Do you regularly clean your strap?
Not really.
Well, interchanging straps helps. Change em out before they get dirty enough. haha
I normally leave this one on all the time. It’s the most comfortable strap I’ve got
It’s technically plausible, but it’s not a practical concern. You might see significant marks after a couple hundred years of wear.
I only have one NATO strap that I wear infrequently, but yeah, that’s completely plausible. Now, what the extent of that will be, I dunno, but on steel watches that I wear a lot (on straps), the caseback is covered with tiny swirls and scratches just from setting down the watch on a wooden surface for years.
At the end of the day, I wouldn’t worry about it.
Lmao so much for tough tool watches if they can get scratched by fabric
Oh my gods just wear your fuckin watch
