Magnification question

[jnmarshall]

Does anyone have a good pic or link to a pic of the date window magnification? Looking for something that might show the magnifications of the minute hand at 15 past the hour.

It's on a slight angle but it's the only one I have.

[rfknauss]

Only one I have showing that.

The only one I can find is of my old GMT II, not a great pic though.

What about it?

Ive heard its an easy way to spot a fake...since Original magnification is X2.5 and fakes rarely go above X1.5....this true?

That's what I'm questioning... My wife's tudor just came back with a new crystal. Originally I was told it had the wrong one and it was not sealing to pass the wet test and pressure test. The service center says it was acrylic and I should have had a sapphire. When I got it back, instead of the $120 I was only charged $40. They said the Acrylic was actually correct for that serial number, but what was on there was the Rolex Acrylic and not the Tudor and they were slightly different sizes or thickness or something preventing it from sealing. The new crystal has the date window as they called it, but it looks like no magnification! Like the fakes. When the minute hand sits under the bubble, it's a perfect straight line of all the same size.

When you say "service center" do you mean a Rolex Service Center? They would not use an aftermarket or fake crystal.

Acrylic and sapphire crystals are not interchangeable. There is only one correct crystal for each case. It is certainly likely that some Tudor and Rolex models use the same crystal.

And yes, it is true that some non OEM crystals do not have a proper cyclops. They may be incorrect in magnification, size or position.

Tried to get a good picture of it.

Ok - that does not look right. Was this a Rolex Service Center?

As said, it must be platic or saphire. There isn't a watch with Rolex case that takes both.

With the correct crystal 99% of modern rolex cases willpas the pressure test.

Rolex and Tudor share crystals but not al of them, I remember reading a post of a wach that didn't pas the test because a crystal 0.1 mm off was mounted.

You can't compare the hands and the date wheel, bacause the distance of the hand to the magnifier is smaller.

Also the date font by Tudor is different from Rolex, it looks smaller.

Which Tudor model is it, that'd help

No, it wasn't the actual service center. Sorry for that confusion. I went there first and got the estimate and was told it required a sapphire crystal. Of course they have to perform the whole service process and I didn't want to spend $500 for a $120 part. I then went to an authorized dealer with a rolex parts account. They ordered the part from rolex. It was a 25-148 Plexi something crystal. I was told it was still an acrylic part and was only $40. I was surprised to see the magnification, or lack there of, upon return. The watch was wet tested and pressure tested and said to now pass.

Case ref is 92413. The serial is 1632xx. The part that was ordered, installed and shown in the pic above was a 25-148.

I understand that a watch takes one or the other. It's just the service center said it took Sapphire and the dealer said the rolex parts center took another.

So you think that the hand and date magnifications look correct?

[Jackxv]

Can you please post a high resolution picture from the complete dial ?

Thanks

Jack

A few photo's to show different font of Tudor

Here's some sort of good news and updated information. Someone in their parts center was willing to talk to me on the phone! He did confirm I have the correct part for that watch as originally supplied by the factory. He also confirmed the magnification on that particular part is only about 1.5x and explained the mfg process between plexi and sapphire(which has a 2.5x peice of glass glued to the crystal and not molded) which accounts for the difference.
The real issue he indicated is now the design of the bezel actually on the watch. He indicated these are different and wasn't sure if they were interchangable. A service tech can easily identify the bezel design. He felt their tech must have identified it as the style requiring a sapphire crystal. The bezel and crystal have to match to seal properly. What he could not tell from a parts catalog was if the bezels were interchangable on that case. That model has two case reference numbers, one ending with an N which are the newer models that ship with a sapphire crystal. He knows from certain experience that in some cases the bezels and crystals can be "upgraded" but could not confirm that from the book. In short if they do not match, they will not seal properly and will still leak.
