I like Hublot but it doesn't hold value well.
The brand gets a lot of flack because even though they have a close to 40 years of history, they all of a sudden came out of nowhere and boomed. They say it's because of sponsorship but really, Omega with James Bond, Tag with Leo, Rolex with Tiger, etc... Hublot wasn't the first to do marketing as such.
They also get a lot of crap because most believe they copied AP Royal Oaks when in reality, they both have the same inspiration, the portholes (Patek nautilus is also inspired by the porthole). I believe 5-8 years after Royal Oaks released, Hublot was also inspired by the porthole but they knew Royal Oak has been out so they started thinking how to differentiate theirs from Royal Oak. They started with the shape, APs are angled so Hublot made their circle. Then they thought of what else AP has and they differentiated the Big Bang to that, one important different aspect was adding a rubber strap to Hublots watches. Back then, no one was even putting the two together, it was more AP RO vs PP Nautilus. Then about 20-25 years later, Royal Oak started putting rubber strap on their Royal Oaks and then the Big Bang models boom a few years later and then Hublot gets the short end of the stick.
Sorry about the brief history lesson there.
Hublot also has eta movements and for the price, many are angered but really it is the quality and materials and look you are paying for. Lots of watch snobs hate them though and feel it is just a Royal Oak rip-off but whatchagon'do?
So yeah I like Hublot, I think they are well designed, uses unique materials like kevlar, ceramic, hubloniom, etc... they created a bunch of different metals to achieve a certain color and effect and toughness. I do believe Hublot made ceramic famous, it being scratchproof was one of their selling points. They also have in-house movements now though not through all their watches.
They are indeed pricey and you'd be crazy to pay retail for them but customer service is top notch. I own one Hublot and been directly on contact with Biver (former CEO of Hublot) and Margolis (former president for US section of Hublot). Biver himself sent me a hand written letter that extended my warranty an extra 5 years. Margolis told me I can order a custom Hublot Classic Fusion at one point because they didn't offer the case and dial combo I wanted. Honestly, you aren't going to get that kind of service from any other brands.
They are also active in the Timezone forums and helps out as much as they can. There was one case where a couple bought a Hublot and one broke or something went wrong by accident and Hublot took care of it.
I am not sure how it is now since they are owned by LVMH but I imagine that just gives them more sources with better materials and movements since they also own Tag and Zenith. I believe Louis Vuitton watches has adapted some Zenith movement to their watches so the partnership is a good sign.
Well that's my opinion and experience with Hublot.
