wheaton26's is lumed with the same lume that Rolex uses, so the colour is correct.

You continously set such a high standard, better quality write up and photo's than the watch magazines on the display stand at my local bookstore. Thanks for this, very well done, and superb photo's.

Remove the bracelet, then install all the spring bars, if the heads are visible, your problem is with the bracelet end links, if the head is not visible, the problem is with the case. It could be either or, this will identify the actual problem...

Actually it's more like I have no spare time due to my day job...till the end of june...only a few hours a week at the bench, and most of that time is spoken for with long time customers...

Don't hand wind it, or you risk stripping the autowinder transfer gear, and no spare parts are available. The problem is a sticky reversing gear, common problem, normally fixed during servicing. You can wear and use the watch, but I would consider servicing if it's a keeper, have it done no longer than a year from now...

I believe it is, having never seen it on an ETA. It is a good idea, now if they would only fix the rest of the design issues...

I first noticed this modification over 2 years ago, it's random, some newer movements are upgraded, some aren't...and you are correct, it eliminates the datechange problem. There is a simple test of an assembled movement to find out if you have this upgrade, turn the hands forward until the date changes at midnight, then turn it backwards to 10 pm or so, if the date DOESN"T change on the backwards movement past midnight, you have the upgraded gears. Great photo's, thanks for this...

Great watch, and great pics... I still don't know how I manage to paint those "T"'s on the dial...no wonder my eyes hurt. My first PAM was a 118, still have it, and still love the feel of the Ti vs stainless cases.

Great choices, remember the sunglasses on the beach, don't want to burn those retina's out with the sights...

It looks as if you have all the parts needed to do the modification, should be straight forward to get it done...

I can't offer any experience with the modifications needed to make the movement into a GMT one, I can offer thoughts on the following based on my experiences... - the calendar and GMT gears are going to be next to impossible to source, I have tried for years and haven't had any success, the only ones I have ever seen were on existing 1575 movements sent in for service. If you don't have those gears, the project is pretty much a no-go. - the post for the calendar gear on the mainplate is almost certainly not long enough to allow you to install the new thicker GMT gear onto it. On a non GMT movement the threads just capture the nut, the new calendar gear is over twice as thick as the standard one, the post is not going to be long enough to allow the nut to be screwed down. This means you are going to have to remove, fabricate, and press in a new post, not an easy task and probably not many watchmakers who can do it. - I would make a ring of brass the correct thickness to place between the mainplate and calendar ring and move the ring up as required (that is if the other issues can be solved). The dimensions are critical, because this will affect all sorts of other things, which I know you are well aware of... - stay away from Yuki cases for this and any other projects where you are installing a gen rollie movement. Yucky cases are not properly made nor do they have the correct dimensions and tolerances to fit gen movements. NDT cases I have used have been good, J&W as well, also stay away from any and all of the modified rollie movements offered by these folks, they are garbage. - there are basterdized GMT movements available, where they use the minute wheel as the driving wheel for the GMT gear, stay far far away from these as well, they are total junk...

k!

The day and date on the 7750 are not designed to switch at the same time, they are supposed to be staggered with the date changing first, followed by the day. The two gears are offset from each other, it's not a mistake in assembly and this offset should never be changed, genuine ETA's have index marks showing the offset of the gears. Just have a look at the assembly procedures on the ETA site to see the offset and alignment marks. 7750 ETA swisslab site assembly procedures click here click on "Assembly", then "Next" until almost the very end and you get to parts "Day star driving wheel" 33.021 and "Date indicator driving wheel" 33.020, you can clearly see the alignment marks and offset. The reason for the offset is simple, it requires a lot of energy to switch the day or date, this is why they only switch one at a time. Trying to switch the day and date together will overload the movement and affect timekeeping, and probably cause the movement to stop running. Everything for a reason, changing one item on a movement will affect a dozen more things, and should never be done without a full understanding of the original design of the movement. Sorry to bring bad news, but I would not recommend this modification be done, it is not a good idea.

6497 is a 1.20mm stem

That's only the tip of the iceberg, you should see some of the stuff I get, I could write a book on this...at least it provides some humour...

Certainly one of my pet peaves, and the reason many get on my blocked list...if you are rude, can't even say "Thanks" or think I am willing to teach you or your watchmaker how to fix a watch, well you're not my kind of people. My favorites are among the following, I get this all the time... Or how about these ones: And of course the normal favorites, PM asking for advice, information, price, whatever, information provided, and nothing, nada, no reply at all, if you don't like the price, advice or reply, at least tell me to screw off... So the blocked list keeps growing, and will continue to do so as long as there are folks like these around. No wonder I take so many breaks from this place, gone again starting tomorrow... There, I feel much better

I still have my RWG watch, along with the boxed set...lumed, serviced, and running strong... Welcome home.

Is the spring from the keyless cover pulled over and engaged into the tab on the end of the yoke arm?

Along the same lines, with the stem out of place, is the clutch gear engaged into and butted up against the crown wheel? Look at each assembly as you assemble it, test and inspect each step, try simply inserting the stem until the square boss engages into the clucth gear, you should be able to wind the watch without the stem actually locked in place. When you find the problem, you will have learned a lot just from the process alone...looking forward to hearing what you find...

You should at least have it looked at so you know the extent of the damage, but I think it will at the minimum require a new balance assembly...

Well from that description of the drop, most likely you have broken at the minimum the balance wheel. And there is probably more damage to the movement. The movement should be fully serviced so that it can be fully inspected, doing the servicing and replacing a broken balance wheel is going to cost over $200, probably $225 and up...depending on how many new parts you need replaced. Movements and cement floors don't mix, it is most likely beyond economical repair...

Since your in the USA, I recommend you contact member vaccum, he can more than meet your needs. I can't imagine anyone being foolish enough to suggest you go outside of RWG, especially for a service that our own members can help you with - lets support our community and each other. Considering the cost, the 112 appears to be a sandwich dial. Sandwich dials require 2-3 times the volume of lume as normal saussage type dials. You should expect to pay just under $150 for a full lume of the dial and hands. Kent, and myself (and probably Vaccum as well) charge more for sandwich dials because of the extra lume. Kent does good work, that is not an issue, but the fact of the matter is he's not a member of RWG, whereas Vaccum has been an outstanding member for 5 years. Because Kent makes his home on PMWF and the other gen forums, he doesn't like his name or work he's done on reps being shown on these forums. I hope you decide to support a member of RWG if you decide to have the lume upgraded.

The quality of the offshore ones is equal to my Horotec and Bergeon dies, he should be charging twice what he does...
