ap-royal

Hi there,

I have all my AP´s done by "Domi" in Germany....look out for his posts here on the forum.

A full service of the movement is around 140 EURO (120GBP, 190USD).

Other option is .... sell your dead watch to me an as I am allways on the hunt for ROO´s to use in projects...let me know what you have,

cheers

Theo

Thanks for the advice. I really like my watch so would really like to get it fixed as long i can get it done for an acceptable price.

IMO: Best is swap the A7750 with a GEN Swiss 7750.

You mean swap the whole movement? is that possible and if so do you know the approx cost and who to go to?

thanks

Dear members,

I need some one in the UK or europe (prefered in UK) to repair an AP offshore A7750 movement. Either the keyless-works is damaged or the teeth on the gears could be damaged, so it might be needed to replace the gear and clean the movement of shrapnel.

Would be very thankful for any advice on who to go to or contact for the repairs and approx how much cost am i looking at.

Thanks very much

I want to review that movement!

Hi Francisco,

I have been trying to contact you regarding repairs to an AP offshore. Had a few questions. I have PMd you, just checking if you have recieved.

thanks

Go with Francisco in Spain. APs running @12 need a special movement treatment. Don't waste your time and money with local watchsmiths.

Given it's an AP ROO...a couple things could have happened...well documented:

Zig's Guide to the A7750

If you set the date while the time was between roughly 7pm and 2am, you could have buggered the keyless works. This holds true for the gen ETA Swiss 7750 as well...it's a design fault. If this is the case, you need to get a watchmaker to fix the keyless works.

If you were winding it vigorously by hand...not a good idea on an A7750. You may have worn the teeth down on one of the gears as pictured here:

and documented in The Zigmeister's Post on Why Handwinding an A7750 is BAD.

The latter will need a watchmaker to replace the gear and clean the movement of shrapnel.

The parts may be replaceable with ETA parts...but I'm not sure on this. You'll have to have a watchmaker familiar with A7750's to know. Check out Francisco or Domenico in Europe for this service.

THANKS TO BOTH OF YOU FOR YOUR RESPONSES. APPRECIATE THE HELP. SO IT LOOKS LIKE I HAVE DAMAGED THE WATCH AFTER HAVING IT JUST FOR A LITTLE WHILE. IN REFERENCE TO "Toadtorrent", IF IT IS ONE OF THOSE TWO PROBLEMS YOU HAVE LISTED, IS IT COSTLY TO GET FIXED? AND ALSO I LIVE IN THE UK, SO THE SPAIN SUGGESTIONS WILL BE DIFFICULT FOR ME. ANY UK SUGGESTIONS?

First, we need to determine what "wind the watch up as normal" means.

It has been discussed by people with vastly more knowledge than I, but a certain amount of care is needed when performing certain operations, even basic ones with the 7750 movement. It's been mentioned on this and other forums that one should take care to avoid manually winding the movement quickly, as this puts an inordinate amount of stress on the gear train, and of course the date should never be changed between 10pm-2am to avoid damaging the date change mechanism. You've gotta remember that a mechanical watch movement is made such that its gears normally turn very, very slowly, and the parts are very, very small and delicate.

So while it could be a construction defect that is just now manifesting itself (seconds @ 12 conversion has many known problems) it could also be an issue related to improper usage. I'm sure that others will shed better light on the issues, but that's generally where the problems lie.

THANKS FOR YOUR REPLY. I TRIED WEARING THE WATCH THE WHOLE DAY TODAY AND MANUALLY WINDING IT A FEW TIMES, BUT STILL NO LUCK. I HAVE A FEELING I MAY HAVE DAMAGED IT BY WINDING IT TOO VIGOROUSLY. IS THERE ANY THING ELSE I SHOULD TRY? AND IF IT IS DAMAGED SHOULD I TAKE THE WATCH TO A WATCH REPAIR SHOP? IS IT A MAJOR OR COSTLY JOB?

THANKS

It's not recommended to manually wind the A7750. Depending on how fast you do it you will destroy the winding gears. Your watch is automatic so you don't have to wind it manually. The big rotor in the back will put power on the mainspring with the right amount of force so the gears won't break.

The chronos use a lot more power than the regular seconds wheel. It will take more power to start the watch if the chrono is engaged.

Assuming it is an automatic (self-winding) watch, the watch will when manually wound in 1 direction & make a whooshing sound (which is the auto-wind/winding).

A properly serviced movement should begin to run when the stem is (manually) wound 5-6 times. However, as is the case for the vast majority of rep watches, an unserviced watch may require many more manual turns of the stem to get it started. The reason is complicated (it usually has to do with an out-of-spec beat), but suffice it to say that you can check the watch by manually winding it (slowly) 40 turns, then setting it (face-up & with the chrono function OFF) on a table & letting it sit there for about a day & a half (36 hours +/-). If the watch continues to run, then your original problem is simply that the mainspring was not charged (wound) sufficient to get the movement to start running. Either wear the watch daily, get a watch winder or be prepared to manually wind it several times (slowly) prior to wearing.

Shaking it too hard is not so good eighter

Seconds @ 12 movement? Too much friction in the gears.

THANKS TO EVERY ONE FOR THE RESPONSES. THE WATCH DOES HAVE THE SECONDS CHRONO AT 12 POSITION. I TRIED WEARING THE WATCH THE WHOLE DAY TODAY AND ALSO WINDING IT A FEW TIMES BUT STILL NO LUCK. I HAVE A FEELING THAT I MAY HAVE DAMAGED IT BY WINDING TO VIGOROUSLY AS MENTIONED BY ONE OF THE FORUM MEMBERS. IS THERE ANY THING ELSE I SHOULD TRY TO GET IT GOING AGAIN? AND IF IT IS DAMAGED, SHOULD I TAKE IT TO A WATCH SHOP TO GET FIXED...IF SO IS IT A MAJOR JOB THAT MAY COST LOTS OR HOW MUCH SHOULD IT COST?

It may be that the watch just does not have enough tourqe to start uop with the stop watch running, have you stopped and reset the stop watch function and worn it a bit to get the wound a bit, i would not recomenend hand winding 7750s,m better to just wear them to let the wind with the auto mechanism.

if you need help with auto winding i recomend wearing the watch and visit your favorate porn site

Thanks for the advice. Im going to try try winding it by wearing it rather than winding it manually. Any reason why manually winding it is not working any more? and also why is it best not to wind manually? and is it supposed to be wound clockwise or anticlockwise (thats when it makes the clicking noise)?

thanks

Hi,

I am new to rwgforum and was hoping for some help.

I have an AP royal oak offshore steel. The watch has been working perfectly since i purchased it. I dont wear it all the time, so after dicontinued use I wind it by unscrewing the crown and winding it clock wise, then changing the date and time respectively. Then screwing the crown back. Since i've purchased the watch, i have noticed that every now n then (2 out of ten times) even after winding and screwing the crown back the watch does not start up. So maybe i thought i was not winding the watch correctly. Should the watch be wound clockwise or anti clockwise? when i wind anti clockwise, it makes a repeated clicking noise.

But now I have a bigger problem. Recently, i was using the stop watch function and without resetting the stopwatch i took off the watch and put it away as normal. 2 days later, I tried to wind the watch up as normal but now the watch wont start. I dont know what the problem could be or am i doing something wrong or is it something to do with the fact that i didnt reset the stopwatch function before putting the watch down so it unwound while stop watch was running?

I would be grateful for some help and advice.
