Apple Watch Ultra 3 Black + Black Milanese Loop - Sapphire Screen Scratches From Official Band?

I recently purchased a Apple Watch Ultra 3 in Black Titanium together with the black Titanium Milanese Loop.

After only around 10 days of careful, normal use, I noticed a small scratch on the sapphire display. I was honestly surprised, because one of the main reasons I chose the Ultra was the reputation of the sapphire crystal being extremely scratch resistant.

After researching the issue online, I discovered that many other users — especially with the black Ultra models and the black Milanese Loop — are reporting very similar experiences. A recurring explanation mentioned across Reddit, MacRumors, Apple Discussions, and other communities is that the black Milanese Loop appears to use a DLC (Diamond-Like Carbon) coating, which may actually be hard enough to mark or scratch sapphire under certain contact angles or impacts.

What makes this especially concerning is that the scratches seem to happen during completely normal handling — mainly while putting the watch on or taking it off — when the clasp or band can accidentally swing and tap the display. Multiple users describe micro-scratches or dot-like scratches appearing very quickly after purchase.

A few things I’d really like to understand from the community:

Has anyone else with the black Ultra + black Milanese Loop combination experienced scratches on the sapphire display?

Did anyone have Apple inspect the watch, and if so, what was their response?

Is Apple aware of the possibility that the DLC-coated clasp/band may be harder than expected against sapphire?

Are people switching away from the black Milanese Loop because of this?

Has anyone found a reliable way to prevent it, short of using a screen protector?

To be clear, I absolutely love the design, comfort, and look of this combination. But for such premium materials and a very expensive setup, it feels wrong that an official Apple band might be capable of scratching the watch’s sapphire display during ordinary use.

At this point, it no longer feels like an isolated incident, but rather something that more Ultra owners are beginning to notice and discuss online.

It is incredibly frustrating to invest in premium materials like a titanium case and a sapphire crystal display, only to find a scratch just days into normal use. You are definitely not alone or imagining things—this specific combination has raised a lot of eyebrows in the tech community.

Here is the breakdown of why this happens, what is actually causing the damage, and your best options moving forward.

The Culprit: DLC (Diamond-Like Carbon) Coating

While sapphire is incredibly hard—ranking at a 9 on the Mohs hardness scale—it is not indestructible. The key factor here is the finish on your black Titanium Milanese Loop.

To achieve that deep, durable black finish, Apple uses a DLC (Diamond-Like Carbon) coating. As the name implies, DLC coatings share structural properties with diamonds. On the hardness scale, a DLC coating can reach a hardness level that is equal to or slightly higher than natural sapphire.

Because the band is a flexible mesh, it is very easy for the metal links or the magnetic clasp to accidentally swing, fold backward, or snap against the watch face while you are taking it off or charging it. If a sharp edge of that DLC-coated titanium contacts the sapphire screen with enough velocity or at a specific angle, the band can and will scratch the display.

Is it a True Scratch or a Material Transfer?

Before panic sets in, there is a small chance the screen isn't permanently damaged. Sometimes, what looks like a scratch is actually material transfer. Because the metals are rubbing together, a tiny amount of the coating from the band can bind to the surface of the glass or the watch's anti-reflective (AR) coating.

The Test: Try cleaning the spot firmly with a microfiber cloth and a tiny bit of water or specialized screen cleaner. If it’s material transfer, it might buff out with some elbow grease. If you can catch your fingernail in the groove, unfortunately, it is a physical scratch.

What Can You Do Now?

1. Visit the Apple Store (Within Your Return Window)

If you are still within your 14-day return or exchange window, your best bet is to pack up the watch and band and head straight to an Apple Store. Explain the situation calmly. While cosmetic damage generally isn't covered by the standard warranty, some store managers may offer a one-time customer satisfaction exchange if you just bought it.

2. Use AppleCare+

If you purchased AppleCare+ for your Ultra 3, a scratched screen is usually considered cosmetic and might be denied a swap if the display is still fully functional. However, if the scratch evolves into a crack, or if it bothers you enough, you can utilize one of your accidental damage claims for a screen replacement (subject to the standard AppleCare+ service fee).

3. Adjust How You Handle the Watch

To prevent the micro-scratches from multiplying:

The Charging Guard: When placing the Ultra on its charging puck, lay the watch flat on its side or face-up, and ensure the Milanese loop is pulled completely straight or threaded so it cannot loop back and snap against the glass.
Consider a Screen Protector: It feels counterintuitive to put a cheap glass or film protector over premium sapphire, but if you love the black Milanese band and want total peace of mind during daily handling, a tempered glass protector will absorb those accidental band strikes.

Not saying you don't have a scratch, but how to proceed is unclear.

On the Mohs scale, Sapphire is a 9 and Diamond is a 10. So Sapphire is very hard and resistant. I imagine you could scratch it with some concentrated effort and some combination of sand and quartz, but I do know that the Apple Watch has its screen plus a coating. Is the scratch in the coating? I believe, based on what I have read in the warranties, that some cosmetic blemishes might be considered normal wear and tear. Hard to say much about this without seeing an image of the scratch.

I have a Series 11 and a simple rubber band but when I take it on and off I would find it difficult to reverse the band to actually make contact with the watch face. But I can see how the titanium band could do that if you take it off in a hurry. Maybe just take it off slowly? I don't know which of the titanium bands have that DLC coating, but "diamond-like carbon" coating sounds like something with potential to scratch sapphire, I don't know.
