New Coke ceramic bezel is cooking, patent revealed

[Yoda_Eating_Pizza]

I hope they don't go completely bonkers and make a VTRO. People will call it the Santa.

[Travis29]

Would be cool to see this come back. Not my fav color combo, so a pass for me.

BLNR is the perfect combo Pepsi is grail.

[GrailTime]

Would the coke be a RONR or a NRRO ?

yesssss !!!!

[inadeje]

There can be only one RONR

Pepsi tastes like crap IMO, and that’s just one reason I prefer coke. Back when the SS BLRO was released, this forum wanted pepsi over coke by eight to one. I know, because I was one of the one’s. Not sure a new coke release would be more popular than the SS BLRO… I get chasing what’s new, just don’t see it having the legs of the BLRO. And really, how many GMT options does Rolex want to offer? They have a bunch already. My guess is coke headlines the next gen GMT and that it’s a few years out.

imo they are going to discontinue one or two GMT options

WG would be perfect !!!

126719LNRO or would it be a 126719NRRO ??

[Cassian739]

I heard Rolex was going to call it New Coke; but then decided on "Coke Classic"

I remember that also. There was a little "it isn't stainless so I hate it" going on. I thought the colors worked better with the warm luster of white gold....but I tend to really like white gold.

I think they should too.

If you go to this page,

https://worldwide.espacenet.com/pate...%3DEP4311820A1

Which is what patent is being claimed, translate it to English, it references green (not red) Which woud tie in with the Green/Black bezel VTNR


1. Process for manufacturing a ceramic watch component, characterized in that it comprises the following steps:

- Manufacture an intermediate component (E1) in the form of a green body based on ceriated zirconia,

- Debind (E2) totally or partially the intermediate component to obtain a debinded intermediate component;

- Impregnate (E3) locally the debinded intermediate component with at least one solution comprising at least one metal salt, from only part of its surface, to obtain an impregnated debinded intermediate component;

- Sinter and heat treat (E4) the debinded intermediate component impregnated by at least one heat treatment step under a reducing atmosphere (E42; E41').



The claims tree tab does indicate red/black as you have posted, however, which may be an update. Perhaps a European patent expert could comment?

‘Green’ in this sense does not mean the color green but rather is a technical term for a ceramic body that still contains organic binders and plasticizers prior to debinding and sintering at high temperature to full density.

This is an interesting patent. The base ceramic is zirconia (like all other Cerachrom bezels except the BLRO which uses an alumina base ceramic). They are achieving red color in a zirconia base (which they previously could not do and had to go to an alumina base) by doping with ceria, sintering in air and finally heat treating in hydrogen to red color (Ce3+) from brown (Ce4+). The other side of the bezel is blue after sintering in air (cobalt infiltration) and turns black after reduction in H2. So you can make a brown/blue bezel or a red/black bezel using this method but not a red/blue. And since this method uses a zirconia base the bezels may be more robust than the alumina based red/blue BLRO bezels.

Thanks for clarifying. Finally someone who is familiar with the these elements.
So, in the end, it is about red/black bezel.

Maybe some stella dial Daytona's? Idk it needs to fit the time too. They just gave us a slew of colorful dial OP's. The coke could be the only predictable model left to show face. What do you guys think?

They would tempt us with bringing back the Pepsi.

Thanks for the technical explanation! Anyway, in more simple terms, it is unobtanium

If they have a red zirconia base, and can do the other side blue or black as per above, then they can make either red/blue or red/black. So probably also applies to a different way of making Pepsi bezel to have all bezels with zirconia base.

No because after sintering in air the Ceria doped side is brown and the side with the cobalt salt infiltration blue. Subsequent heat treatment in a reducing (hydrogen) atmosphere turns the brown side red but also turns the blue side black. If you want to make a monobloc part you can’t have one side change color and not the other unless you could somehow shield one side from the H2 at 1400+C!

..or they could just stick a nice vibrant red bit and a deep royal blue bit together, I don't understand what would be so terrible about doing it the easy way instead of inventing a hard way.

[Justincredible]

I talked to an AD a few days ago and he said it's not happening. Another AD said the coke is a strong possibility. The suspense lives on.

As in a platinum GMT with a blue/brown bezel?

This!
Whatever a new GMT is released, I hope the dial size can be 2-3mm smaller

Absolutely. Never understood why they didn’t go this route, it would be infinitely easier and a hell of a lot more cost efficient.

Figures I just recently decided I was not buying any more Rolex watches. Well the good news is I'll never be able to acquire one anyway.

Haha I never said it would be nice. I dislike the platinum Daytona due to the brown, so this would be along the same lines for me as well.

[Gebbeth]

It will be another GMT that will be unobtainable at retail and retail prices.

Agree with this. I can't recall a single release that was as manic as the stainless BLRO at Baselworld 2018. I personally believe that single release brought a ton of the hype we see today to the watch market. 116500 Daytona in 2016 was a close second, again IMO.

[Order 72]

Your guess is as good as anyone.
