When comparing the rehaut, or "French ring," of a Rolex between genuine and replica models, there are several key details that enthusiasts and experts alike should consider. The rehaut is the inner ring between the dial and the crystal, often engraved with the Rolex logo and the serial number on authentic models.

On a genuine Rolex, the rehaut is typically characterized by precision and clarity. The engraved Rolex crown and serial numbers are meticulously aligned, and the depth of the engraving is consistent across the entire surface. This precision is often lacking in replicas, where the engravings might appear shallower, misaligned, or uneven. Furthermore, on many replica watches, the rehaut engraving may look etched rather than engraved—a subtle but significant difference that can be discerned under magnification.

Rolex also employs UV light as a security feature to authenticate their watches. Under UV light, certain elements on the rehaut or the dial may reveal additional details that are invisible to the naked eye, such as specific markings or patterns designed to confirm the authenticity of the watch. For example, on some models, the coronet logo may glow, or certain parts of the dial might react differently under UV light compared to a replica. This is part of Rolex's sophisticated approach to preventing counterfeiting, ensuring that even subtle features contribute to the watch's overall security profile.

Beyond the rehaut, Rolex also integrates UV-reactive inks and materials into other components of their watches. The luminescent material used in the hour markers and hands often has a specific reaction under UV light, glowing uniformly and distinctly—a detail that is hard to replicate. Additionally, on some models like the Rolex Pepsi bezel, the colors may show unique reactions to UV light, with genuine bezels displaying a consistent and subtle fade that is difficult for replicas to mimic.

Another secret measure involves microscopic engravings or symbols that are only visible under magnification and UV light, such as tiny Rolex logos within the print of the dial or hidden on the edges of the hands. These details are nearly impossible for replicas to accurately reproduce due to the advanced technology required.

A particularly interesting application of UV light is seen with the Rolex Pepsi bezel. On a genuine Pepsi bezel, the red and blue colors may show specific reactions under UV light, with the red often having a particular glow and the blue maintaining a consistent, subtle tone. Replicas often fail to accurately replicate these UV-sensitive properties due to differences in materials and manufacturing processes. This makes the UV reaction of the bezel another reliable point. Although I have seen 3rd party CNC Pepsi bezel makers who have pretty must mastered a rep 1-1 Pepsi UV bezel.

In contrast, most replicas fail to replicate these UV-reactive details accurately. While some high-end replicas may attempt to mimic these features, they often fall short due to differences in materials and manufacturing techniques. As a result, the absence or poor quality of these UV-reactive elements is another indicator of a replica when scrutinizing a watch.

In summary, while the rehaut and UV-reactive features might seem minor to the untrained eye, they are crucial in distinguishing between a genuine Rolex and a replica. The precision of the engraving and the presence of UV-reactive details are both testaments to the craftsmanship of Rolex, and they serve as essential tools for authenticating these luxury timepieces.

To further enhance the authenticity of replica watches, manufacturers have begun paying closer attention to the intricate security measures used by Rolex. Improvements in materials and production techniques have allowed some high-end replicas to better mimic the precision of rehaut engravings and even introduce UV-reactive elements that closely resemble those found in genuine Rolex watches. However, despite these advancements, there remains a significant gap between replicas and the real thing. The key challenge for replica makers lies in achieving the same level of detail, consistency, and subtlety that Rolex employs, particularly in the execution of UV-reactive features and micro-engravings.

As technology progresses, it is likely that replica manufacturers will continue to refine their methods, making it increasingly difficult to differentiate between a genuine Rolex and a high-quality replica. Nonetheless, Rolex’s commitment to innovation and security means they will likely continue to develop new, sophisticated measures to stay ahead of counterfeiters. For now, the best way to ensure authenticity remains a thorough examination of these security features, especially under UV light, where the differences between a genuine Rolex and even the best replica can still be discerned.

I have to admit that paying all that kinda money needed to improve or buy a virtually undetectable replica watch is wasted IMO.

Reason being, let me see, how many times has someone come to me and asked, can I put the UV I carry everywhere on your watch ?

Errrrrrrr, nope never. And even in a nightclub scenario, who TF will be looking at me and my watch with all those half naked / sometimes naked dancers ?

Nah, I think the only one that is being fooled by this is the person that buys or mods the watch to that standard ;)

But what if I mod a gen Rolex by dipping the whole bloody thing in invisible to the naked eye, UV reactive paint?

Check and mate, Rolex!

Anyway, I’m sure it’d come in handy next time they’re checking rehauts with loupes down at the local M&S at gunpoint, that being a very common occurrence and all.

The UV over the crown on the rehaut is more reflection than being coated! if you look at the video its the difference in the quality of the lume the gne will be much brighter, but to be fair the clean models are really very close.
The difference is if you give a rep to an RSC or someone who handles them all the time they are gonna know, they are just gonna know, and wont wast time authenticating it based on looks! They will open the back and its obvious, decorated movements even if copies still do not use th egen style balance wheel or springs.
Fooling someone out and about or even handing it over to someone who knows a bit will pass the test, but giving it to a dealer to authenticate will never work!

You’re spot on about the UV effect. it’s more about the reflection quality rather than any special coating. Genuine Rolex watches definitely have a superior lume and reflection quality. Clean models are impressive and the closest with all their models to gen in most cases. And you are 100% correct there are still subtle differences that even experienced dealers can spot or just feel if somthing is off, especially when they open up the case.

I have to correct my earlier post, As far as I have found the CF Pepsi bezel is fully UV.
I thought it's was a 3rd party maker.

Also, just to clarify the reason for my post was not to nit pick silly details. This was for my own education and I just felt like sharing.

I don't claim to be an expert by anymeans and am a sucher for details and how quickly the rep game is getting to next to flawless clones over the past few years. It also might help others from not being scammed if they where to buy a gen with out checking.

And trust me im laughing with you all over carrying a UV torch around checking everyone Lex.
But if I was going to buy a gen from some shop that isn't a AD, I'm definitely bringing my own UV torch. 🤣
Especially if the refuse to remove the case back. 😅

And yes I do use chatGPT to feed in information to filter for me with long and detailed post like that. Unlike my replys that are all my words. I'm sorry I cheated and failed on the essay geting a F-, please forgive me. 🙏
I'll go back to pen and ink and aim for a AAA++++++++++ next time. 😁

Here are some video's of the CF stock bezel under UV below. I'm very tempted to get a CF Pepsi soon.
😊✌️

There are ever so many better ways to have ChatGPT to write for you.

Take for example this rewriting of your text which I told the 4o model to rewrite using select 18th and 19th century words in the style of a pirate. ChatGPT told me it would “set it alight with some old-world verbosity and the briny tongue of a scurvy sea dog”.

Has it achieved that which I instructed it to?


"When comparin' the rehaut, or as them landlubbers call it, the 'French ring,' betwixt a bonafide Rolex and them scurrilous imitations, ye best be keepin' a keen eye on the minutiae. The rehaut be that inner ring twixt the dial and the crystal, often adorned with the sacred markings of the Rolex clan—a logo and serial number, both etched with the precision of a master shipwright carvin' his name into the prow of his finest vessel.

On a genuine Rolex, the rehaut be a testament to the watchmaker’s meticulous craft, where every engraving—aye, the mighty crown and the serial numbers—be aligned with the discipline of a crew marchin' to the bosun’s orders. The depth of the engravings is as consistent as the tides, showin' none of the pox-ridden flaws ye might find on a counterfeit. These knock-offs, ye see, are often marked by engravings that be shallower than a lubber’s puddle, misaligned like a drunkard’s stagger, or uneven as a storm-tossed sea. And beware! For on many a counterfeit, the engraving might look more etched than carved, a subtle difference but one that a savvy pirate can spot under a glass as sharp as a cutlass.”

Never knew this. Thanks for setting me straight, unlike the rehaut on my misaligned rep

(Actually it's just the dial that needs slightly turned to restore alignment but never mind).

Hark! Now shall I, xray7, tak this yonder passage and render it in the wyse of Chaucer, with wordes as olde as Canterbury Tales themselves:

"Whan comparinge the rehaut, or as some wolden calle it, the 'Frenche ryng,' bitwixen a verray trewe Rolex and thilke false replicas, it behoveth a man to have a ful sharp eye for the smale details. The rehaut, yt ys, the inne cercle bitwix the dial and the cristalle, ofte y-engraven with the markes of that moste noble hous of Rolex—a signe and a serial numbre, both y-carven with the subtiltee of a craftesman who hath spente many a yeer in his arte.

In a verray trewe Rolex, the rehaut ys a mirrour of the werkeman’s diligence, where ech engraving—yea, the coroun and the serial numbre—be y-set with the stede of a knyght in araye. The depe of these engravings is as evene as a stille lake, with nary a flaw to be founde. But on thilke false counterfeits, ther engravings ben oft shallowere than a dry welle, missealigned as a dronken swerver, or uneven as the wagginge of a dogge’s tail. Therfor behoveth him a ful long spoon That shal eat with a feend, for on many a false wach, the engraving semeth more y-etched than y-carven, a diffaunce so sotel that oonly a man with a verray keen eye might espy it, perchance with a magnifyinge glass, as sharp as a knyfe."

How doeth this transformation sit with thee? 'Tis a fair blend of olde spellings and Chaucerian tone, methinks! A pox on ye ChatGPT, vile pretender!

Sorry to tell you this is crap, i saw at least 3 Rolex models directly in AD store, including my submariner, who arent aligned as some reps.
Thsi is also true, not all Gens I have seen are perfectly alinged, some a slightly out, not by much but enough, also photos can distort this too! Im sure they perhaps should be almost perfect but these are hand built and as such will have slight imperfections in the same way as the crown never properly lines up if the watch is laid down to rest pictures will have you thinking is should be vertical. All the new models and others Ive had over the years have never been perfect.

I suspect the rahuat non alignment may just be down to the seating of the movement when assembled, but Im ure there will always be a few where they will be ever so slightly out and will pass QC from RO as they know it its genuine and if they were to authenticate they just take the case back off and check the movement serials against the case serials and then make sure the movement is gen.

Well next time I will bring some tools to the AD then to make sure its a gen. :ROFLMAO:

Cool its an interesting post, and I dont think anyone is gonna hold you to it as such, I think the rehaut is mostly down to lume strenght and having had a clean and gen side by side on Sub and GMT they are really very close, when using the UV the gen is perhaps a little more vibrant as far as dial lume goes but hard to say there is much difference, ive seen older reps where the lume is a lot less bright when compared side by side but now even the cheaper ones seem to be on par. The finish on the rehaust itself on cheaper reps are a little less finished so will reflect less, but again the clean models and some GMF one are very close even under mag, Som perform a poilsing of the rehaut on theirs which will enhance the reflection but not all gens are highly polished and the Clean models and VSF Subs are very consistent in the finish, (the polished models ive seen do look great though and Im surprised RO dont polish them all up but I suspect that is to avoid reflection, (its not a mirror polish mod its just a remove the grain style poilsh).

The UV on the GMT Pep insert is pretty much the same and is not actually a feature at all its down to the way its made. Its a red ceramic insert that is then re-coated in a thin layer of blue ceramic and then polished back and laser cut. The layer of blue is much thinner and as such when UV is applied the base red shines through and will match the red section as if the blue was never there.

Reps find it hard to do this (to be fair RO find making the pepsi pretty hard to get the colours they want) but many of the first ones were just cheap ceramic and then painted for the look, now they pretty much use the same techniques as RO by using proper ceramic suppliers. This is still a big tell as only a few factories acutally use the more expensive UV inserts.

The Clean V2 version was UV and was a rep of the ealier RO release with lighter pastel colours and then the V3 with the later darker colours from 22 onwards. (the V number is essentially made up by the community and factories) it seems to now only relate to the insert version rather than any other specific updates to the watches themselve although minor tweeks will be inlcuded (its hard to tell really)

The biggest tell between the 126710 models is the movement, the older versions had a 3186 movement (VR of SH or other) This is the correct movement for a 116710 GMT but was decorated as 3285 for some of the earlier Jubille models until the clone 3285 movements apeared with the DD dandong 3285 being the premium version much as the VR was for the 3186

The difference is the way it winds the VR min and hour hand or just hour hand wound clockwise, where as the 3285 movement does the same but when changing just the hour hand (once you have set the GMT hand) this roates coutner clockwise to advance the hour hand as per the gen.

Hand one of the earlier watches to a dealer and they might spot this instantly and decline to further look at it, (the average Joe is unlikely to know this) but in the same way as alot of grey dealers are not Rolex trained they seek to look on site like this for help and the guy in your video, which in itself helps the rep factories improve.

The reps these days are really very good and most normal people or even jewelers would not spot the visual differences instantly and may even fall for some of the Clean GMT's, but they would never payout until it had been fully inspected and opened up and that when they would break the bad news, that either you are trying it on (but ofcourse your were not, honest guv!) or that you have been misled and have purchased a rep and your should go back to the person you bought it from!

Testing a rep against a dealer is a test and if it were to pass initially then fair play but not something that is gonna end all that well.

Good post though and good topic, there is a post on the forum on the V2 vs V3 comparison that is well worht a read too.
