How has everyone's experience with the modern JLCs been?

[kertong]

Doing some searching; it looks like the modern JLC movements are all over the place in terms of accuracy? I wanted to share my experience here to see if this is common or not..

My wife and I bought a brand new JLC Master Ultrathin Moon (a.k.a Mooney McMoonPhase), on Dec. of 2017 to celebrate a big promotion she got at work. When we get it home, I carefully admired/inspected the dial, and saw this deep gouge in the sunburst pattern:



But our AD made things right - swapped it out the next day with a new one that they had on hand. Filled out a new warranty card and everything, so we definitely got a "new" JLC to replace it. But, that was strike #1.

Strike #2 - after a couple weeks, my wife notices that it is behind 3-5 minutes from her iPhone. Doesn't think too much of it; corrects it to match her iPhone time, and a week later, it's already behind 2 minutes. So I start using Watchcheck on Android and start timing it. Here's the results:



IIRC, it came out to average out to around -10.9s/day.

I show this to our AD; and they've been great, they immediately sent it into JLC with the -10.9s/day figure noted for service.

Strike #3 - We get it back a smidge over 4 weeks later, and I start measuring it again. Results:



:O It's worse!!


My questions:

1) Obviously this isn't *normal*; but it seems like modern JLC movements are kind of inconsistent; I have a friend who has had multiple modern JLCs and he noted that their positional variance was crazy, and that they all tended to run slow. What are your thoughts/experiences on this? I expected better from a watchmaker with this history and reputation; but am I being unrealistic? Is this ok?

2) What would you do in this case? Despite the "1000 hours master control testing", *AND* a factory regulation/service, it's even worse. My contact at the AD (great service btw) is insisting that we send it back in with the watchcheck screenshots to "get it right", but this will be another 4-6 weeks without the watch; and with the first service making it worse, I don't have high hopes!

3) We're thinking of selling the watch; but if it runs *this* badly, we wouldn't feel too great about some poor person ending up with a lemon. What would a fair asking price for this be, given we disclose the -20s/day performance? I'm even seeing some posts that JLC may even claim that it's "within spec" as they don't officially list specs or conform to COSC?


And a final thought (or a treat, for reading this far): I don't want it to seem like I'm just badmouthing JLC. There's another JLC Piece I have that I love - and a genuine factory one (not engraved).
