Glashütte Original

Most likely a silly question , but has anyone tried adjusting their GO's to better the watch rate. It seems like it would be fairly simple by carefully removing the case back and slowly turning the swans neck screw and using a little patience and common sense. I have a GO Senator that is running about 10-11 seconds fast a day and would like to make it run a little closer to 0-2 seconds a day.  Any thoughts and help would be great.

Thanks for the feedback,

Mark

I think it is possible to adjust the swan neck to regulate the watch. You would need to have a time grapher machine and experience to perform it correctly. I would suggest that you send it to a authorised watchmaker for servicing, they would ususally check the watch for accuracy and regulate it after the servicing.

Personally, I feel that the potential downside outweighs the benefits, especially if the watch in question is under warranty. I admire Jeff's technical acumen and sense of adventure, but I won't be following in his footsteps anytime soon . . . cordially, Art

Thank you all for the feedback on adjusting the swans neck, that is quite a link, Art.  Jeff has really done some work to get his watch well adjusted. The GO Navigator I have is no longer under warranty, and though I don't think I would tackle this with any other watches I own, the GO seems a bit more user friendly as far as adjusting goes. That caliber 39 swans neck just peers up through the caseback calling for some slight attention.

I will give this some thought and let you know if I actually give it a go. If it was just 5-8 seconds fast, I think I would most likely live with it never even contemplate this adjustment, but 10-12 seconds or more a day seems like it is getting a bit too much out of  good overall time keeping. There is always the possibility of a trip to the watchmaker. We will see.

Thanks again,

Mark

I agree w/ Art Unless you have a .6 mm screwdriver, a Dissecting microscope , A good light , and a really clean environment .Don't attempt. I work in the micrometers and nanometer environment every day so it was not a problem. You might find a jeweler who will for a price give you a multiple adjustment package in a months time . I did find that the watch had to settle in a bit The best I was able to get was about 2-3 sec fast every couple of days. according to the atomic clock. Beside I have to set the watch every other month anyway I know get the 100 mvnt and I won't have that problem. I'd do it for you but don't think you want to part w/ the watch for a month .

Hi Jeff,

Nice to hear from the man who gave me hope in doing the rate adjustment. I have been a tinkerer and mechanic just about my whole life so I decided to give it a try. Following your basic rules, tools needed and clean envirornment (as much as possible) I carefully removed the caseback and adjusted the swans neck to slow the rate down.

After two or so days my GO Senator Navigator is now running about +1 second a day (against the atomic clock),  I will see how it goes over the long haul, but my first impression is good to say the least. Hopefully it will remain close to this range, that would be terrific. Thanks to everyone for all the help and advice and I doubt any watchmakers out there should or would worry about my beginners luck at rate adjusting. I am just happy the watch now is running close to it's best.

Thanks,

Mark

Congrats on the adjusting. Keep us posted on how accurate the watch remains for you.

My watch has settled on to about 1 minute slow every 2 months. I use the stop watch alot at work so i think that function slows it down a bit even thoug i have it set for about 1-2 sec/day fast. As long as it is consistently fast or slow is the impt part from what I have read here. What did and how did you  adjust the watch? 

regards

Jeff

Hi Jeff,

Thanks for the e mail. The watch is still running about 1-2 seconds fast a day. I am much happier to have it working this well, I was worried it was just getting too fast before the adjustment I did.

To adjust it I removed the back very carefully, tried hard to not lose any screws and ever so slightly moved the swans neck screw, to slow it down. I did need to look up slow and fast in German to get the right direction going. I did this adjustment with a super small screwdriver and magnifier a couple times to fine tune it and then fully tightened the case backs screws down like a wheel lug nut pattern and that's it.

I hope this will be my extent of watch tuning 101 for a while, it is nerve racking on a nice watch like the GO Navigator. I would feel so silly handing a watchmaker a failed attempt, still in pieces. Maybe next time I will try this on beater...ha ha.

Take care,

Mark

. . . I admire your sense of adventure and willingness to take the next step in watch appreciation by getting involved technically . . . I'm afraid I don't have the guts to tamper with any of my  Glashütte Originals . . . regards, Art

I thank you for your admiration and understand your position perfectly. I would say my watch adjusting days are behind me as well.
