Blemish

[direwolf]

Has anyone else gotten these marks on the underside of the clasp where it rests on the bracelet? I have used dish soap, a toothbrush and water and they are not coming out.

I have the same thing on my Sub. It drives me nuts! Luckily, it’s on the inside and I can’t see it until I’m putting it on or taking it off. Hope someone has a good answer for us on how to get rid of it. Ultrasonic doesn’t work.

Yep, this is par for the course. You can do your best to rub it off, but it will reappear.

Ok. Thx for the comments. Glad it is fairly typical, although I didn’t notice it on my previous sub. Anyone know why this happens?

This is the result of continuing metal to metal contact in the bracelet. Each time new surface is exposed some oxidation takes place, even with stainless steel. Not to worry about in my view. A mild acidic solution (CLR is one) would remove but I would not use it on a fine watch.

Looks terrible. I'll give you $10K for it.

Metal and metal touching does that. You'd have to have a piece of plastic there to prevent it and it would be unsightly.

The good news is that at the rate you're abrading the two surfaces (100u per year) the clasp should come apart in about 20,000 years.

Exactly that and nothing to be concerned about as it happens with all metal contact when friction metal to metal is involved, except for perhaps giving some Rolex owners something to moan about.

Use to rip apart golf clubs for fun n put them back together because from factory nothing ever worked for me and every now n then you can add a little to much heat removing a head that leaves a discoloration on the hosel but they made a product called “blue away” mostly for the ti stuff but on ss it would remove any cook marks n leave the hosel looking freshly polished new. I almost wonder if that same product would wipe away that oxidation mark n keep it from returning. The stuff worked wonders and wasn’t very messy like a liquid pasty consistency and all you’d need after was a warm water rinse to remove any excess.

Would Bar Keepers Friend work? They have a SS cleaner with these ingredients:

Water, Isopropyl Alcohol, Propylene Glycol, Mineral Oil, Surfactant, Preservative, Glycerin, Fragrance

Could a little dab of this once in a while hurt??

Stainless steel is "stainless" because it forms it's own passive coating due to the chromium content which combines with oxygen in the air.

If that passive barrier is rubbed at continuously, which happens with metal to metal contact, then some corrosion can get a foothold.

The fix is to polish the corrosion out so that the chromium can again form it's protection film.

This is the same phenomenon that happens at casebacks where the gasket sits. It is the constant movement of the gasket, breaking down the barrier, that lets corrosion start. Another reason for regular maintenance.

Contact burnishing.

A non-issue; every bracelet from every manufacture will have this.

Wear is wear.
