Quality Control Issues?

Jan 08, 2021,14:03 PM
 

After waiting all year to see this model in person, I recently purchased a JLC Master Control Chronograph Calendar.
I really like the looks and features of the watch. It reminds me of vintage triple date calendar watches from the 50's.
Unfortunately, after testing the watch for a few minutes, I found that the chronograph was not working. The minute register 
was not incrementing at all. It just twitched at one minute intervals. 
I retuned the watch and the AD requested that another be sent out as soon as possible. 
Well, the second watch came in and I picked it up, only to find that it too had a problem with the chronograph function! 
Each time I stopped the chronograph, it caused the continuous seconds register to jump forward by several seconds. 
The amount of jumping varied between 0 and 5 seconds and caused the watch to gain time.
Fortunately, the AD was very understanding and helpful and addressed the issue.  In conversation, I also heard 
that another instance of the same watch had been returned with issues. 
This really makes me question JLC's claim of 1000 hour testing. It only took me a few minutes to find these issues. 
I thought the group should hear about my experience, in case anyone is considering this model.

Very very helpful post, and sorry to hear about your troubles. I’m becoming more and more skeptical of internal QC certifications (like the 1000 hour of JLC or superlative chronometer of Rolex), especially when compared to companies that go the extra mile... 

QC externals

My METAS tested Omega is not accurate anymore. Not that it runs bad, my Omega is still between the METAS tolerances. When winding the crown, it have a resistance i do not mentioned when i had the watch 5 months ago. The idea that a watch can be serviced i...

Thank you. I hope JLC can resolve the issues with the new caliber 759, because it's a beautiful watch. Maybe down the road it will be ready for another look.

I do hope so!

BOTH my Extreme Lab 2 and Duometre went back to JLC last week for chronos not resetting properly

 
 By: Fastwong : January 8th, 2021-15:49
This is the 4th time going back to service for the Duometre and 2nd time for the EL2. Neither watch had issues with the chrono before I sent them in. On return they both worked fine for a day or two, long enough to check them at the boutique and confirm f... 

Same to you! The base 751 chrono movement is tried and true

 
 By: Fastwong : January 8th, 2021-16:42
So I'm not inclined to believe there is an issue with the movement design or architecture but in the assembly and qc. It's good to hear the AD is taking care of things, but JLC really needs to step up to make sure they deliver you a working watch. Only th... 

Sorry to hear your unpleasant experience.

Perhaps the 1000 hours is more just on the accuracy of the time piece, complications are somehow overlooked. I hope it will be resolved to your satisfaction soon.

I am truly sorry to hear that, I am thankful none of the JLCs I had, had any issues, I think I had 8...

Either way, this sucks, to get a watch and have it not work properly, I hope it gets sorted out.

Am embarrassment for JLC and much appreciate your sharing

It happens that I’ve been eyeing this watch for possible purchase, I now reconsider

Seriously beautiful watch

 
 By: jj.hansen : January 9th, 2021-03:26
My AD had one in and I almost pulled the trigger a couple of weeks ago. Ultimately I decided against it as I am liking greater simplicity in my watches. Ive owned about 10 chronographs and never used that function. I hope it gets worked out as it is gorge... 

Hi ardbig - PM me - I'd like to compare notes with you about your watch

I have been connecting with owners of this watch offline and happy to share what we know.

Too bad from JLC

Sorry to learn about this bad experience. My «old» Gran’Sport Chronographie runs perfect, but not the same dial of course. However I am also very happy with my Zenith 410 LE - same face... ...  

Similar issue with mine

 
 By: cerulean : January 10th, 2021-19:38
In my case, it happens only occasionally. Perhaps 1 out of every 4 times I stop the chronograph, the running seconds will jump 1-2 seconds, and pause before continuing. Trying to get a video or two. I have not contacted my AD yet as it is very sporadic. S...

Happens shortly after the running seconds passes 50... www.dropbox.com

Yes, It looks like you have the same issue, but the jump is slightly less.

 
 By: rudy500 : January 11th, 2021-17:50
I saw a jump forward ranging from 0-5 seconds. The amount of the jump seemed to be related to where the chronograph was stopped. After about 15-20 seconds, i saw a large jump.
