There was never a 16710 with engraved rehaut.

On the other hand, it's worth noting that the gen of the Portuguese uses the exact same hack on the exact same base movement. IWC does a much better job of it and jewels everything, of course, but the IWC 79350 is essentially just a regular 7750 with a transfer plate.

It'd be fine if it was built for a 7753, but it's not. It's built for a 7750 with a transfer plate, so the case/stem height expects the extra thickness, and the subdial spacing isn't quite the same.

Did you try... google? 1570 datewheel (google image search, 3rd result) 3135 datewheel (google image search, 5th result) 2836 datewheel (google image search, 4th result)

I have a frankened-up one for sale...

Use a 2846 with GMT. It's easy to build. I did a build thread a while ago. Gives you the best of all worlds: low beat, can use ETA hands, etc.

You can see some blue in the pic.

Well that person is an idiot. There are differences, but they are tiny. Any 2824 will swap with any 2824-2 and vice versa. All external dimensions are exactly the same. Yes.

The date-at-6 and date-at-3 movements are identical. All that differs is the printing of the datewheel itself.

Congratulations. (Am I the only one who thinks, if I picked up a gen AirKing for $700 with a beautiful open six datewheel like that... I'd have the movement beating inside a MBW 1665 and be working on a franken AK to give to my son? It's a disease, I tell ya.)

Sure, maybe he did. But basic dimensions are basic dimensions. The reason for the sunken datewheel is that the movement sits too far back. The reason the movement sits too far back is that there is usually a transfer plate on top of it. Moving the movement forward means moving the entire movement closer to the dial, which means the stem no longer aligns with the tube, which means the tube needs to be moved. Unless he built a tiny gearbox to offset the stem by 1mm, then he moved the tube somehow. The stem now goes through a place that was metal before. Therefore that metal had to be removed. Some things you can't get around. It's simply not possible to do this any other way.

Pics are gone, but polexpete's old thread here http://www.rwgforum.net/topic/134327-navitimer-stem-alignment-for-gen-etas/ Basically, he drills a new hole and uses JB weld to close the old hole. There's no secret.

Charitable of him. In any case, it can't be that much of a "trick"--the stem height has to be changed. No way to do that short of drilling a new hole for the tube. The only "trick" is how you want to install the tube in the new hole and close up the old hole.

"at least" = not yet produced. So I sent in my money for a pre-order. That's fine, I guess, but I kinda wish he'd told me that. My message read "do you have any of these left" and his reply was "Sure I have some."

Are these ready to ship? I just paid for one, but there's a thread over at RWI that suggests they haven't been produced yet.

There is not one. It does not exist. Don't know how to make this any clearer for you. There is a CHS-modded 2836 (I own a few and have done teardowns/writeups in the past) but it does not have exactly the same functionality.

Nope.

And your girlfriend is fat and ugly. Seriously, dude, you couldn't find anything nice to say? The new version of the AR on the cyclops looks great.

Unless it means 36,000 bph. "High beat" and "low beat" are relative, not absolute, terms. And often you'll see 21,6 called "high beat" when compared to 18kpbh movements.

Yeah, "tennis"... sure

Score, that was my first guess Well swapping it out is a simple matter of removing the dial and hands, swapping the part, and reassembling. But since it's a Rolex part I bet spares are hard to find. Re-crimping should definitely be left to an expert.

If the hands are not the proper size, they'd be flopping around, not simply not turning.

Cannon pinion needs to be re-crimped would be my guess. (EDITED TO ADD: that'd be my guess for an ETA movement, btw--I think the Rolex movements are also direct drive so it should be a valid guess still, but I'm no expert)

True All 2824 movements are going to be 28.8kbph unless someone did something funky to it once upon a time. Usually here at the Rolex subforum when we say "low-beat" we mean 21.6kbph, we don't see many 18k movements here. Over at the Panerai forum it's different. (Also, we usually mean 21.6 but sometimes mean 19.8 since a lot of the older Rolex movements like the 15xx beat at that rate--clear as mud, right?)

All 2824s are high-beat.
