Vincent, as far as I can tell the lugs are exactly the same on the GMT-II and the Submariner

Please enlighten–
The newest Submariner has had its lugs widened–are these lugs now the same size as the lugs on the newest GMT II, or are they in fact even more substantial. To me, the latest iterations of each model appear to have equally sized lugs.
Thanks in advance,
Vincent

Only the Day-Date II has a parachrom hairspring. Rolex will not upgrade.

Please answer a question for me. Does my 2004 Day-Date have a Parachrom Blue h/s? If it does not, will Rolex upgrade to the pbhs when the watch is serviced, or can this be done by reque$t? Thank You-Vin

John, having witnessed the manufacturing process of the parachrom hairspring in person in Geneva, I can tell you beyond a shadow of a doubt that the blueing process takes place after the hairspring is rolled and pulled through dies to its final shape and coiled and ready to be crimped to a collet and welded to a stud. It is white in color until the blueing process. It is a fully functional hairspring in its white form, the blueing simply protects the hairspring.If you look closely at the video on the Rolex website about the Parachrom, you can see the color of the spring and it is clearly white. And it is more resistant to shocks simply because it is so much thicker than Nivarox springs.

Alex, I believe Patek uses a silicon based hairspring which is also resistant to magnetic forces. Patek’s hairspring was developed at a Swiss University in a joint effort between many different brands, Rolex included. My understanding is however, that the Parachrom hairspring was developed uniquely by Rolex and is not found in any other watch brand.

Hello, I appreciated very much this review. Concerning the parachrom spring I wonder if this has not been a joint development together with Patek Philippe? They mount a similar part into their recent models.

Cheers Alex

I actually spoke with James Dowling in New York about three weeks ago on this very topic, and I’ve been speaking with my contacts at Rolex USA in an attempt to resolve the controversy. At present, James agrees with me that the non-blue hairsprings found in any 4130 movements ARE NOT Parachrom. The blue color of the Parachrom hairspring is a direct result of the manufacturing process, and a byproduct of combining two elements to create the Parachrom allow – as soon as the newly formed element hits oxygen, it turns blue. As he and I understand the manufacturing process, it is physically impossible to have a Parachrom hairspring that isn’t blue. The most logical explaination here is that the the Parachrom Blu hairspring has not been on the caliber 4130 from the begining as was originally communicated, though I have not received confirmation of this. I plan on updating my article on http://www.rolexreferencepage.com once I have a final answer.
