Does JLC do the 1000 hour test on time pieces when they go in for a complete overhaul? The service center tells me We perform a test that isnt exactly a 1000 hour test, but is the exact equivalent during our quality control process and saves time in orde... 

1 000 hours are something like 42 days... That's long! Best, Nicolas

Thanks Nicolas, for your response. It is then a misnomer to call it a 1000 hour test. I wonder though, how it is simulated?

Good grief.

Re submit their watches to the COSC when they service them... I am not sure at all they do it, but I may be wrong... Best, Nicolas

Hi, While I realize that the 1000 hours test is a major selling point for JLC buyers, I view it as more of a final step in the production and quality control process than a mandatory battery to be passed every single time the watch is serviced. Just like ... 

My master perpetual is being serviced there as I write this. I will post back experiences about the service experience and also about how well thee timeepiece keeps time.

do NOT send them back to COSC after a service. They usually put it on Witschi machine and regulate it to +2 or 3 seconds/day. -Dean

If I'm not mistaken, it is Vivek who asked the service center if the Master 1000 Hours test is performed and someone there replied with a slight no whereas they should have given a firm no to avoid any confusion. It would be wrongful of them indeed if the... 

Hi, Certainly, nobody I have spoken to at JLC Texas has implied or claimed that the 1000 hours test is repeated there. However, they have claimed to shoot for performance that would put the watches well within published COSC performance parameters if meas... 

The watch is back from the service center. However, the presentation was pretty bad. The watch was randomly wrapped up in bubble wrapped and stuffed into a box and that UPS box was simply floating around in a larger box! No polishing cloth nothing! The wa... 

Hello All, I didn't get around to consistently wearing my watch and keeping it on a winder till now. I find that the watch consistently loses 8 seconds a day with mixed use (wearing, winder). I have been tracking time against Is such a deviation consider... 

No message body

If it is regularly at -8 per day, it is not a problem. You give it to set it a bit faster. Best, Nicolas

Thanks! I typically can tolerate a max of 3 secs a day

Better than the COSC: -4 / +6 secs per day. Best, Nicolas

This is what they are telling me. The watch is in ther hands as we speak; According to the Swiss Master Watchmaker, he advised your Jaeger LeCoultre Master Perpetual Timepiece is losing 8 seconds a day with is within factory specifications. Is there anyth... 

Hi, Since we're discussing JLC service, and this topic has surfaced several times, it seems that many questions arise concerning factory service... with surprisingly few hard facts available. This isn't unique to JLC, but the brand is our focus on this fo... 

And, for once, no problems in naming your AD since he is an important part of the process. Best, Nicolas
