Rolex Crown question

[MackThePen]

This is possibly a very stupid question, but I'll ask it anyway. I understand that the markings on a Rolex Crown indicate the level of sealing. What does a cross indicate - I can't find this information anywhere, and haven't seen a similar crown anywhere else? Photo uploading has defeataed me again, so I am putting in a link to Flikr, where I have stored a picture of the crown -

You have to wonder why all the replies are from Scots - don't we have jobs to go to?!

Common on some Tudor models - cross (or plus sign) is the middle bit from the swiss flag. :)

I have seen it before - on a 50's Rolex - but no idea what it means!

Something to do with the Swiss symbol perhaps?

Information borrowed from Timezone.

One Dot (.) = Twinlock on a Platinum watch

Two dots (..) = Twinlock on a Gold watch

Three Dots (...) = Triplock

1 Dash (-) = Twinlock on a SS watch

There are exceptions to those rules.

The older crowns that were Gold plated also had the 2 dots(..) but they are not on current watches any more.

I think the cross is an abreviation mark that means "patented"

Some early rolex crowns had the word "brevet" which also means patented in French.

I think you are right.

Here is an early "patent" crown on my Oyster Centregraph.

Wow. Live and learn. Never noticed that before!

Got the Brevette + querie cleared up this last August from Rolex St James Sq
London.

I had the conversation with a receptionist at Rolex counter who went away.
He came back with an answer from a collegue, who was retiring after 48 years service that week.

Back came the answer Brevette( patented) + (Swiss) but Swiss Government objected to Rolex using the + sign considered it belong to Swiss Gov, after that the + sign not used again.
Hope this helps.
