Baselworld 2018 Introduction

The Rolex caliber 3285 was the only new Rolex movement announced at Baselworld 2018.

3285 vs 3186

The new caliber 3285 movement replaces the caliber 3186. It has a larger overall diameter allowing for a larger barrel offering a 70 hour power reserve. The caliber 3285 also has the updated Chronergy escapement allowing for 15% more efficiency as per Rolex claims.

The caliber 3285 is only used in the newer GMT-Master II models:

  • 126710
  • 126711
  • 126715

Superlative Chronometer

Rolex labels the new caliber 3285 as a Superlative Chronometer, claiming that it is two times more precise than an officially certified chronometer with an accuracy of -2/+2 seconds per day “after casing”. Superlative Chronometer is an in-house version of testing that goes beyond COSC parameters.

From Rolex:

With 10 patent applications filed over the course of its development, this self-winding mechanical movement is a consummate demonstration of Rolex technology, at the forefront of the art of watchmaking. Calibre 3285 offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, convenience and reliability. Calibre 3285 incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference. -Rolex.com

At this time, there is not much else known about this movement. Rolex has only shared a 400px x 400px image with the quote above. This post will be updated as we learn more. Please add your thoughts and comments below…

Is this movement anti-magnetic?

Rolando Harris

Yes, with the para-whatever-thingamajigs.

Yes, but not at the level of the Co-Axials than can withstand 15000 gauss and above, even near MRI machines. I know, I have the OSPO Chronograph with the 9900 movement and had a chest MRI done in September 2019, and my watch was in my wrist inside the tunnel, and is still ticking with a + 2 seconds accuracy……

They let you wear it?

No, the Tech did not know I had it hidden in the blanket I was given to cover my body. When he realized I had it, it was already too late, the scan had finished, and he was kind of crazy about the fact, but there were no alterations to the test, it was a scan of my chest looking for metastatic tumors, and I got my watch, and it was and is working. It is an Omega Seamaster Planet Ocean Chrono with the 9900 caliber in a rubber strap. I am happy for me….

Sorry for being completely off topic, but if the Omega co-axials can withstand 15’000 gauss even in the 9900, then does that make the 8508 a gimmick?

Jorge Robles
Jorge Robles

No, All Omega 85XX movements are resistant to 15000 gauss, actually they were the first META Certified at that level. They include manual hand wound and the automatic movements. Omega 93XX and 99XX are Automatic Chronograph movements. The 85XX so far does not include chronographs, only chronometers. My question is, Why an 8508 is a Gimmick? Which is your argument or point for the question?

The rotor looks cool. I wish Rolex made watches with open case backs. Don’t you?

Rolando Harris

No, then it wouldn’t be an Oysterproof.

Is it worth 10 grand??

It is a very good watch. It is not worth ten grand for the name!

You can now hear the rotor as they have done away with bushings. The bearings need to be worn in after about a 3 month period. All mt other Rolex’s were silent, so this put me off a bit initially. New Pepsi GMT Master II BLRO. Now I love this watch. In the four months I have had it, it has gained 14 seconds. That is pretty impressive for a mechanical watch.

Does the 3285 have the Paraflex protection? Its not mentioned on the Rolex page for the GMT II but is on the Explorer II page.

Jorge Robles

Yes, you can see it very clearly in the picture, together with the blue-parachrom hairspring. The movement is antimagnetic, but not a the level of the newer Co-axials. The new 3235 and derivatives are about the same level to this one, maybe a little bit better.
