I see this thread is quite a few years old, however, has the A7750 movement improved any since these were posted?

Hi guys,

Wasn't sure where to post this - let me know if this is the wrong place.

I am a first time buyer looking to get https://puretime.io/big-bang-evolution-44mm-ss-black-dial-ceramic-bezel-on-black-rubber-strap-hub4104.html
I know this isn't a TD on RWG but is on RWI
I have been looking online and there seems to be quite a lot of issues with the A7750 chrono movement (more specifically with sec@6 & sec@12)

I have had a look at the first page of the forum with all the advice on how to own/maintain a 7750 movement - Very helpful - I will 100% be following this guide.

So my questions are
1. Is there a TD that specializes in Hublot replicas?
2. Is there a TD that specializes in the Asian 7750 chrono movement as I would like to reduce the possiblity of this failing as much as possible?
3. I see a lot of mixed posts on whether to service or not for different movements. Which of the below options would be best for the, expensive to service, 7750?
    a) Service when received and then again every 5 years till it dies.
    b) Don't initally service but do every 5 years onwards
    c) Use it as soon as it arrives until it breaks, then get it repaired/replaced (not sure if this is a good way to about it, however saw it mentioned so thought I'd include)
4. Where would be best to service, considering price to get this done (I live in UK)? After contacted the support team and they said they offer servicing for $120. Guessing this would be to the same standard as other places?
5. Is it worth getting this on purchase to avoid shipping fees/time to do so within the first year?
6. What is the average life expectancy on the 7750 movement
7. Is it worth ditching chrono replicas all together and going for something like the below with a more reliable 2824/2836/2892 movement (both beautiful watches but this has nothing on the chrono IMO)

Sorry for all the questions and thanks for the help :)

Will try to give you helpful answers but remember to use the search function if you don't find something straight away.

1. TD doesn't specialise, they all can get the same stuff except for some rare things which some TD are better at finding, but Hublot isn't really concerned.
2. Same answer as above, plus even if they were, they wouldn't service it before hand without an added cost
3. a) If you can, it's good ; b) It's not that bad to use this method but you have to be aware that it may fail ; c) same as previous, that's the "I don't care, it's a toy watch" approach :D 
4. The A7750 is a complicated movement so the hardest part will be to find someone willing to service it locally (and you'll have to be patient). Price quoted is good as long as you are sure they'll be doing the work correctly.
5. If you go with the TD service, definitely get it done before shipping
6. Impossible to predict, it will depend on how much you wear the watch, in what conditions, etc... Could last 2 months, could last 5 years, could last 10 years
7. Ditching chrono movements that are not quartz is definitely the easiest way to avoid the problem, but if you like chrono that shouldn't stop you (as long as you are prepared for the failure risk). Other movements are more reliable but they can also fail. If you can find a chrono with a manual wind ST19 you can go chrono without hesitation.

Thanks for all the info, really helpful.

Think I'm gonna start with a simple (non-chrono) watch first and go for this next. :)
