dosanim Posted September 16, 2006 Report Share Posted September 16, 2006 I recently got 063 GMT PAM which I'm very happy with. However, I noticed that when I compare the US official time clock, over the duration of 24 hours, 6 sec ticking faster. Occasionally, GMT hand gets slightly out of sync. I don't know if it is typical problem or not. Is it possible to calibrate this movement so that it can be fairly accurate? When will be the best time to do service? I tried search, but nothing ame up. I don't know if I entered wrong clue. Thanks in advance! Quote Link to comment Share on other sites More sharing options...

If I understand what you're saying, the main time keeps pretty steady time, and doesn't fall behind more than is usual for automatic watches. But the GMT hand will sometimes lag behind, i.e. you've got it set three hours behind but it doesn't always stay there. If that's what you're saying, then there you will have to send the watch away to have the movement fixed. Apparently, there is a little clutch that controls the GMT hand and it is known to slip a bit. It's not a matter of the accuracy of the watch, but it is caused by a mechanical problem is the watch. Not a terribly serious mechanical problem, but a problem nonetheless. Thanks, Zach Quote Link to comment Share on other sites More sharing options...

The COSC standards for Mechanical watches, is -4 to +6 seconds per 24 hours...that is achieved on only the most expensive watches, after adjusting by specialized watch timers... You have a $400 replica, never adjusted or worked on by any specialist, and it's as good a timekeeper as a watch costing $1000"s more... Your well within the BEST Accuracy of any mechanical watch, if this is not accurate enough, my suggestion is to get a Quartz, as no mechanical watch can be expected to keep up with a atomic clock...

RG This is a great point, Rob. Many people new to the world of automatic watches don't realize that there is no way that ANY mechanical timepiece can be as accurate as quartz. It's not about having lower expectations, it's about having different expectations. Quote Link to comment Share on other sites More sharing options...
dosanim Posted September 19, 2006 Author Report Share Posted September 19, 2006 Well, I think it's about understanding what to expect from automatic movement. Right now, without adjusting, since time of post, it is about 20 sec ticking ahead of time. If that's the way it would be, then I\ll just have to accept that. BTW, well come back The Zigmeister. Your advice is always welcome. Quote Link to comment Share on other sites More sharing options...

Your advice is always welcome. Not a problem, you have one of the best movements ever made, as far as I am concerned, the ETA 2892A2 and it's derivitives, are far superior to any Rollie any day (cheaper, thinner, and no Rotor bearing rubbing problems like the Rolex models). You have an excellent watch, a keeper for sure... Glad to be back. RG Quote Link to comment Share on other sites More sharing options...
dosanim Posted September 19, 2006 Author Report Share Posted September 19, 2006 Thanks Rob. As stated, mine is 2836-2 mod for GMT movement, but I hope it is equally good one. Regarding servicing of PAMrep and mod, and Re-lume of hands and markers, what is your usual procedure? Would you PM me about this? Thanks!

If your getting 6 seconds per day on a 2836-2, your doing really well, as the specs on this model are + - 20 seconds per day... RG Quote Link to comment Share on other sites More sharing options...
