Help needed, spots on the watch

[Megamax]

Dear friends, I bought this watch from a non TD in Turkey few weeks ago and wore it few times. This morning I realized that there are very small spots on the steel parts ( grayish color). Does anyone have a solution on how to remove it? Or the right question is is it something removable? [emoji4] Thanks in advance for your valuable feedback. Cheers

Scotch brite should fix it

More info might help spur response; such as
have you worn it into the sea?
what general exposure has your watch had?
When looking closely does it look and feel like solid steel?
etc.

No sea no water, wore it couple of times during office days, I think it is steel

Looks like corrosion on low grade steel to me.

Considering these are not from the TDs (and even from them our expectations are not that high compared to gen manufacturers), I would not be surprised if that were corrosion.

seems to be a KW pam312?

As far as I know it is but I am not an expert though

I find the materials our reps are made from a little suspect.

I have worked with exotic and stain resting metals for over 4 decades. That, and I have products from Gen companies that are made from the materials that the rep companies claim they are using.

I have Gen Pams that I have worn for years. They show NO Where near the scratches and wear marks the Rep's do. And I am careful with both gens and reps equally! This is in the Stainless watches.

My experience in Ti. comes from both using it, and owning products from several grades of Ti.

Odd that the Rep companies, as well as the actual Gen companies rarely mention the grade of Ti. used. Without the grade being known, the title Ti is almost meaningless.

For instance, there is a High End AG manufacturer in England that braggs that their flagship offering is 7075 Ti. Well, 7075 is not Ti at all. It is a very high grade of Alu. Particularly if it has received a T6 Heat treat. (This is a company that makes high pressure, pneumatic Air Guns costing from over one, too thousands of dollars each)
Even this, highly respected company is misleading in the materials they use.

So how could we expect better from makers of clones!

I do know this, I have several Ti fitted Custom Knives, that I carry at least one every day, and have for years. Not a scratch on any of them. Where Stainless handles would be well marked by wear. The excuse that Ti. is softer than stainless is well, far from correct. "IF" a quality grade of Ti is used, it is much more abrasion resistant than a low carbon type SS such as 316.

I have NO Idea what grade of Ti. a Gen Pam uses. Haven't been able to find any info in that regard.

To say that a product is made of Ti, 20+ years ago was a huge selling point. It was considered to be very Exotic. This is not so much the case today. To simply tell the customer that it is Ti, is tantamount to telling us that our watches are made of metal. Yes they are, but this is virtually useless info. Metal could run the gamut from lead to platinum.
The big question here, is what is it, and does it have a heat treatment, and what kind.
Without any kind of info on specs, it is meaningless., and incredibly misleading!

Its not much of a citation, but FYI I did find this:

"... the titanium used by Panerai is Grade 2 whereas most of other watch manufactures use Grade 5.
It makes a big difference as Grade 2 is much more prone to scratching that Grade 5, and even more than stainless steel."

Unalloyed Commercially Pure (CP) Titanium is available in four different grades, 1, 2, 3 and 4, which are used based on the corrosion resistance, ductility and strength requirements of the specific application. Grade 1 has the highest formability, while Grade 4 has the highest strength and moderate formability.

CP Titanium users utilize its excellent corrosion resistance, formability and weldable characteristics in many critical applications. Titanium Grade 2 is stronger than Grade 1 and equally corrosion-resistant against most applications.

Titanium Grade 2 has numerous applications in the medical industry. Biocompatibility of Titanium Grade 2 is excellent, especially when direct contact with tissue or bone is required.

Titanium Grade 2 is typically used for:
– Orthopaedic applications, such as implants and prosthesis
– Airframe and aircraft engine parts
– Marine chemical parts
– Condenser tubing
– Heat exchangers

As to Urine, pretty much any grade Titanium is resistant. Urine will eat the crap out of Aluminum and Brass/Bronze (to some extent) though.

What will eat Titanium?
1. Sodium Hydroxide (drain cleaner)
2. Sulfur Chloride (insecticides)
3. Sulphuric Acid (used in making phosphate fertilizer)
4. Trichloroacetic Acid (used for chemical peels and wart removal)

Thank you for your efforts in the explanation Sir!

I am not familiar with the 1,2,3,4, scale. It is not how we order Ti at all.

For custom folder scales, I use Ti6al/4v. This does not fit any of the 1,2,3,4, scales.

It is very scratch resistant, and is predictable in machining, but must use a good carbide while machining, such as C-6.
