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…

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

No, then it wouldn’t be an Oysterproof.

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.
