The Big Bang is synonymous with Hublot, and 2025 marks the 20th anniversary of the Swiss brand’s signature model. Among its novelties presented this year in Geneva at Watches & Wonders 2025, Hublot has unveiled an exclusive five-watch set that showcases its mastery of transparent case materials and celebrates two full decades of Big Bang timepieces. Produced as a limited edition of just five examples, the new Hublot Big Bang 20th Anniversary “Master of Sapphire” Set consists of five separate UK perfect replica Hublot Big Bang MECA-10 watches, each one crafted from a different color of transparent sapphire or SAXEM.
Aside from their colorways, the five Big Bang MECA-10 watches that make up the Hublot Big Bang 20th Anniversary “Master of Sapphire” set are otherwise identical, although none of them are models that currently exist within the brand’s catalog. Aside from the fact that these five best fake watches represent the first time that the MECA-10 has been rendered in sapphire (or SAXEM), the “Master of Sapphire” models are also a different size than their standard-catalog 42mm and 45mm counterparts. Although their cases still follow the blueprint of the Big Bang series, with a sandwich-style construction and clear sapphire crystals fitted to both the bezel and caseback, the new Big Bang MECA-10 “Master of Sapphire” models measure 44mm in diameter by 15.3mm thick, and they also have a lower depth rating than their siblings with 50 meters of water resistance.
Internally, the quintet of models from the site replica Hublot Big Bang 20th Anniversary “Master of Sapphire” set are all powered by the brand’s manufacture Caliber HUB1201 manual-wind movement, which can also be found inside the original 45mm versions of the Big Bang MECA-10. Running at a frequency of 21,600vph (3 Hz) with a 10-day power reserve (240 hours), the 24-jewel Hublot Cal. HUB1201 consists of 223 individual components, and it features black-plated bridges with a silicon escapement. Similar to other 45mm MECA-10 high quality copy watches, the five “Master of Sapphire” models display their power reserves with a skeletonized gear on the lower half of the display, and the unique power reserve indicator is driven by a “crémaillère” rack system, which consists of a linear gear connected to circular gear, with the mechanism proudly displayed on the upper portion of the dial.
Since the cheap super clone Hublot Big Bang 20th Anniversary “Master of Sapphire” MECA-10 watches are powered by the same movement as their 45mm siblings, their dials offer an identical layout, rather than appearing in the streamlined display of the 42mm MECA-10 models that debuted earlier this year at LVMH Watch Week. Featuring a pair of centrally mounted hands with the running seconds displayed by a register at 9 o’clock and a power reserve indicator at the 6 o’clock location, the five “Master of Sapphire” shop replica watches all feature transparent sapphire dials to fully showcase the mechanics of their internal movements. Additionally, all five models each echo their respective colorways on their hands, applied hour markers, and minute track, with small red accents highlighting the key pieces of information within their power reserve indicators.
Each of the five colorways from the Hublot Big Bang 20th Anniversary “Master of Sapphire” set represents one of the brand’s proudest moments from its journey with transparent case materials, and despite the “Master of Sapphire” name, one of the five models (ref. 424.JY.4890.RT) is crafted from neon yellow SAXEM. The other four Swiss made replica Hublot models that make up the “Master of Sapphire” set are crafted from clear transparent sapphire (ref. 424.JX.4820.RT), water blue sapphire (ref. 424.JL.4890.RT), deep blue sapphire (ref. 424.JM.4890.RT), and purple sapphire (ref. 424.JM.4890.RT). Aside from the neon yellow SAXEM model, the rest of the colorways reside on the cool side of the spectrum, and certain colors of sapphire that have previously appeared on luxury fake Hublot watches (such as yellow, orange, red, and pink) are notably absent from the “Master of Sapphire” set.
All five of the models from the UK buy replica Hublot Big Bang 20th Anniversary “Master of Sapphire” set watches are completed by transparent rubber straps that match their respective colorways. The actual design of the strap is identical to what can be found on other Big Bang models, with a tapered structure and linear grooves on their outer surface. Just like other Big Bang models, the straps for the “Master of Sapphire” series connect to the case with Hublot’s One Click system, which allows owners to disconnect the strap by simply pressing the two trapezoid-shaped buttons located on top of the watches’ integrated lugs. All five straps secure on the bottom of the wrist with a deployant-style folding clasp made from titanium, and the set comes packaged in a backlight display case with an engraved plaque that reads “Master of Sapphire XX/05” (although no images of the box are included among the various press materials).
Considering that all of Hublot’s colored sapphire models are six-figure timepieces, a box set containing five sapphire MECA-10 high end replica watches in different colors is guaranteed to be rather expensive, the Hublot Big Bang 20th Anniversary “Master of Sapphire” set is undeniably aimed solely at serious collectors with a penchant for colored transparent cases. At the time of writing, these “Master of Sapphire” models are the only MECA-10 1:1 wholesale fake watches crafted from sapphire, and with only five of these sets available, each watch is essentially a one-of-five limited edition. That said, given that colored sapphire is one of Hublot’s signature case materials, I’d be shocked if we didn’t eventually see this ultra-hard transparent material make a follow-up appearance on the MECA-10 series at some point in the future.
