Parachrom blue spring

[chaisson]

Anyway to tell if my random serial number 14060M has a parachrom blue spring without taking the back off?

[kilyung]

Nope and it's not that significant enough to worry about it. It's really not that different from the outsourced spring Rolex was using.

Mike, not concerned / worried about the difference, just was wondering if there was a way to tell. So you have to take the back off? Troy

That would be the only way Troy!

So....in seven years (with any luck) I'll know at my first service.

Not significant but looks good.

I thought it was a given that the random s/n 14060Ms had the PB spring.

It does indeed... more reason to get a clear case back!

You may be correct but I believe there's no really knowing when Rolex started using it.

Here's a qoute from Padi as it relates to the hairspring:

Now Nivarox thats the name of the alloy much like Rolex calls there Parachrom.Today it is used mainly in the watch/clock industry, but also in other micro-machine industries and in certain types of medical equipment and high presicion surgical instruments. There are several variations of the Nivarox alloy depending upon the intended application. These alloys are stainless steel alloys with high concentrations of Cobalt (42-48%), Nickel (15-25%) and Chromium (16-22%). There are also small amounts of titanium and beryllium. Hairsprings made of this alloy are highly wear-resistant,and they are practically non-magnetic in normal wearing,and non-rusting and possess a low coefficient of thermal expansion.

Nivarox 1 through 5 is a series of grades of hairsprings with number 1 being the best quality. The most commonly encountered Nivarox hairsprings in the watch industry are grades 1 to 3. The alloy is unaffected by heat and normal every day ordinary magnetic fields. There is however, also the Anachron hairspring which is said to be of even higher quality than the Nivarox No 1 grade.Who knows perhaps that the grade that Rolex used over the past 40 odd years.Although magnetism mainly effects the hairsprings other parts of a watch can get magnetised too,but its a very very simple process to de-magnetise any magnetised watch today.


Fact specs from Nivarox Far and other research .

Yes it's likely but I don't think Rolex threw out their stock of Nivarox springs just because of new serial numbers on the cases. They'd have gone through their inventory and started using Parachrom as soon as necessary. Kind of like the 3186 in 16710 discussion. Rolex has never stated that random serials have the new spring. The correlation between serial numbers and new springs is entirely an Internet observation.
