first of all please excuse if my english is not perfect - it is not my native language.

During 40 years+ of watch collecting I have seen a lot of watches and have come across a few of these really rare early pre Carrera dates in waterproof screw back cases.
I have not seen more than 10 examples and 5 of them I have had in my hands and had the opportunity to examine them carefully.
Most of them are in poor condition of the dial or they are badly refreshed. But I have seen 5 original examples and they all have differences in their dials. Different tones of silver. Different surface structure. Different sizes of the blue numbers of the date. Slightly different sizes of the luminious numbers, some are signed SWITZERLAND - some not, etc. So my conclusion is that the dials were produced from different dial manufactures in different years.

Today I would like to discuss a very special and unique dial of a 2547 2923 together with you in detail. It is the only salmon dial I have seen on a watch like this so far.

When I looked at it for the first time I thought it is clearly refreshed / reprinted because it is so different from all others I saw before. I looks less vintage than the others I know.
I took it out of the watch and discussed it with two friends. These two friends do dial restaurations for 40 and 20 years now.

After a very careful inspection we all three came to the conclusion that this is an authentic and original dial - and now I would like to know your thoughts!
Our opinion is based on many facts and will mention five of them here:
1.the round hour indices (silvered) have clearly not been remashined or altered. They are not applied to the dial but fixed.
2.alignement of the scales (especially blue date to 1/5th of the second scale) is as precise a only manufactures did.
3. surface of the dial is absolutely precise (the two colors effect which is done by different light reflection by brushing in different angles)
4. back of the dial looks absolutely unaltered not regalvanized
5. even more important: the small circles around the dial feet (the do come from manufacture machining process are still there, original and visible. They are always gone if a dial is regalvanized.

So please take a careful look at the other high res and detail pictures of this dial which I took:
