Didn't know about the S on the service glass.
Interesting, thank you.

[JGJG]

That is a technically impressive bit of photography! Didn’t know about the service s either...

Excellent post. One to bookmark!

Thankyou Jocke

Jocke, l don't believe you are capable of posting a bad post!

Very interesting and, as always, great photography.

Very informative with clear pictures.

Thank you~

A good post, Jocke - thank you!

I didn't know the dots making up the crown were actually tiny stars at different angles. Good info for checking authenticity.

Thanks

Is the stars (crown) visible when installed or only when not fitted?

Either way incredible photos

Great info .. thanks for posting that ;)

Very interesting, I don't really know much about photography but I'm guessing that it was very hard to capture

You can see it when the glass is fitted in a watch, though it can take some practice to find just the right focal length through your 10x. You won't be able to see it without a loupe and against a light coloured or fussy dial (Jubilee etc) it can be very difficult.

Best to practice on a dark-dial watch in natural daylight, focus on the six o'clock marker on the dial underneath and then slowly withdraw at a 45 degree angle (ahem) until the coronet comes into focus. Steady hands!

I have recently seen some very good fakes of the glasses (sorry, ten pages here we come) which were better than earlier, crude fakes. The latest ones were made up of dots in very smart pattern, but they were at incorrectly uniform depth within the glass (and I suspect they won't have been star shapes, either).

If you have good eyes, it is my experience that if you wipe the thin edge of the glass so that it is spotless and grease-free (not easy) you will be able to look through it, along the 6 - 12 transverse of the glass and see that the coronet is in fact angled, such that the top and bottom are at different heights from the dial.

When did they start adding the laser logo?

I believe that the service “S” coronets were introduced at about the same time as the introduction of coronets outright, so circa 1999 but I do seem to recall that many watches were sold later than that, still without the lasered marking.

Many correct, unmarked glasses were used for years afterwards and I still have some here, ex-watchmaker stock.

There is also the puzzling email I have posted before :

Thanks Haywood, I ask because my GMT 2 I bought in 2001 does not have it engraved and that had me concerned.
Speaking of fakes, I have seen a good quality 4060M fake with ETA movement from C 2000 with an extremely good lasered coronet which made me think it had a proper Rolex glass fitted.

[Jocke]

Thanks guys.

Haywood you are correct about the introducing. If I remember correct so was the Daytona and YachtMaster the first ones that got it in 1999.
