An interesting article about the hairspring

[jochen_1962]

How important is this part for the general accurancy of the watch - you write it is the "heart" of the whole mechanism ?

Hallo,

the steel daytonas got the engraved rehaut in the Z series.
The yellow gold daytonas with leather strap got the engraved
rehaut much earlier; I have one with D6....
So the rule mentioned above is only valid for steel daytonas.

Isn't it mentioned in the booklets whether the watch contains
a parachrom bleu ?
I can check my booklet on the weekend.

Have a nice day

Hallo,
sorry, once again, but I had to make sure not to
be wrong.
I don't know how to insert a link but
- search for "parachrom in der daytona"
- and you get an article written 5.2.2007 from OrangeHand

There is the information that Rolex produced before 2006
a barachrom (without) hairspring. Because of slight changes in
the material it got bleu.
From this article I got the opinion that the 4130 has parachrom
with or without bleu; but I would like to get more information.

Thanks in Advance

The balance and the hairspring pretty much determine accuracy.

Hmmm...I'd like more information here as well.

Incidentally, I've updated the article with some new information.

Bericht eines Forumskollegen:
Freitag, 4. April 2008, Basel. James Dowling kehrt mit neuen Infos von Rolex zurück.

Ich: "Was ist denn der Unterschied zwischen der alten Parachrome bleu-Spirale und der neuen Parachrome-Spirale?"
(what is the difference between the old and the new spiral ?)
J.D.: "Die sind identisch". (they are identical)
Ich: "Die neue Spirale ist also auch amagnetisch und temperaturresistent?" (the new one is as unmagnetical and temperature-resistent as the old one ?)
J.D.: "Ganz genau." (yeah)
Ich: "Aber sie ist nicht mehr blau?" (but it in not blue ?)
J.D.: "Doch". (wrong, it is !)
Ich: "Und warum heißt sie nur Parachrome?" (what does the new name
parachrome stand for ?)
J.D.: - no idea !

Hallo,

jochen_1962

As much as I understood from the articles here in the
forum:
- the first parachrom hairsprings were not blue
therefore not recognized. But these were produced
by Rolex inhouse and have nearly the same attributes
as the later "bleu"s.
- then Rolex improved/changed production and the
hairspring got this nice colour and the name parachrome bleu.

This is what I have in mind from reading the forum.

Have a nice day

Johannes
