Longest time ETA 2824-2 goes without service

[Blnrwearer]

There is a thread for Rolex and I'm curious about ETA 2824-2 as it's deemed as a very reliable movement.

How long did your ETA 2824 based watches last w/o a service?

I have a 2005 Tag Heuer aquaracer that's still kicking. Never been touched but the date still snaps over quickly at midnight.

I learnt a great deal over the years from this brilliant watchmaker and watch repairman,currently the distinguished resident of the Omega Forum, Mr Al Jenskey of Archer Watches.Would you like to know the answer to your question? Then read what Al has to say

Good read!

For this article, I have 2 points:

1. We know oil will dry out but we don't know whether it dries out at the same speed regardless the watch is in use or not. And lubricants have been continuously improved so the time it takes to dry out will be different between different generations of oil.

2. He said customer said the Rolex Cal 3000 was “running well and keeping great time” but he didn't verify if this is a true statement. A test result from a timegrapher would be good. I suspect amplitude/beat error/rate would be pretty bad.

I think most people agree that at some point, a watch will need to be serviced. The question is the service interval and how we determine the interval objectively. But the answer of "it depends" (his answer) is not satisfactory...Generic 5-7 years is not satisfactory either since everyone's use case is different.
