SKX013 Ceramic Bezel Insert (Slope) - Submariner Blue

See It On A Watch

The Submariner Insert. Ceramic. For the SKX013.

The bezel insert is the ring you actually read. The classic 60-minute diver's count-up scale — legible, timeless, and the fastest way to give your SKX a Submariner face.

This one is fired into scratch-proof ceramic with a mirror finish. A luminous pip sits at 12 o'clock, so you can still find noon in the dark. Slope profile, adhesive-backed and pre-fitted — it seats on the SKX013 OEM bezel (or any similar-dimension bezel) the way Seiko fits its own.

Questions, Answered

Everything worth knowing before you build.

How does a bezel insert attach?

With a double-sided adhesive disc that's included and already fitted to the back of the insert. Peel the backing, line the insert up with your bezel — 12 o'clock to 12 — and press it down firmly for a few seconds. No press-fit, no glue, no tools; it seats the same way Seiko fits its own inserts.

Will an SKX007 insert fit an SKX013, or vice-versa?

No — SKX007 and SKX013 inserts are different diameters, so they aren't interchangeable. Match the insert to your case: SKX007/SRPD inserts for the SKX007 family, and SKX013 inserts for the SKX013, SKX015, SKX017 and other 7S26-0030 cases. If you're unsure, check the "Fit Models" line in the Specs.

What's the difference between a "slope" and a "flat" insert?

It's the top profile, not the fit. A slope insert angles up toward the crystal for a raised, more three-dimensional look; a flat insert sits level. Both seat on the same OEM (or similar-dimension) bezel — so pick whichever look you prefer; it doesn't change what it fits.

What are the bezel inserts made of?

Four lines, each with its own character: scratch-proof ceramic with a deep, glossy finish; lightweight aluminium; solid 316L stainless steel; and lumed sapphire.

Which bezel inserts glow in the dark?

Some do — look for a luminous pip at 12 o'clock. Every steel insert has one, and the BGW9 steel and lumed-sapphire lines use a 100% Swiss Super-LumiNova® BGW9 pip (a cool ice-blue glow, up to eight hours on a full charge). Three ceramic Submariner inserts — black, blue and green — carry a lume pip too.

Do I need a bezel to use a bezel insert?

Yes — the insert is the printed ring that sits inside your bezel, so you need a bezel to hold it. It fits the Seiko SKX013 (or SKX007) OEM bezel, or any aftermarket bezel of the same dimension. Replacing both at once? Grab the matching bezel from the "Pairs with" links. For a bezel from another brand we cannot confirm a fit — check with whoever supplied it.

Can I remove or reuse a bezel insert?

Yes. You can lift an old insert out with a thin, blunt tool — our bezel & insert install guide walks through removal. The adhesive disc is single-use, so once it's off it won't stick again — but you don't need a fresh insert to reseat one: cut a few small pieces of any double-sided adhesive tape, place them on opposite ends of the insert, line it up and press. It holds just fine.

SKX013 Ceramic Bezel Insert (Slope) - Submariner Blue

Excellent finishing and quality. The appearance of the blue colour varies depending on the lighting. It looks like a rich, deep blue but turns into loyal blue under the bright light. This bezel insert definitely elevates the look of my watch.

Dear Sir or Madame,
Would you please provide the inner and outer diameter measurements. Would you tell me is this a bezel insert that is taped on or pressed fitted into place?
Thank you.

Hi Stephanos,

Thank you for your interest in the SKX013 ceramic bezel insert!

It shares the same dimensions as the OEM Seiko insert — an outer diameter of 33.7mm and an inner diameter of 27.5mm. As for fitting, it isn't press-fitted: like all Seiko bezel inserts, it's held in place with double-sided adhesive tape, so installation stays clean and simple.

Hope this helps — please let me know if you have any other questions.

Best regards,
Adriel
