Patrick_y, a respected moderator on WatchProSite, delves into the groundbreaking Rolex Land Dweller 7135 movement, asserting its position as the most advanced in the world. His detailed analysis, supported by technical specifications and comparisons to other horological innovations, provides a compelling argument for why this movement represents a significant leap forward in mass-produced watchmaking. This article explores the nuances of 'advanced' versus 'complicated' in watchmaking, highlighting Rolex's bold strategy in integrating multiple new technologies simultaneously.

Moderator Patrick_y celebrates Rolex's achievement in creating the most Advanced Movement In The World!  


When we use the word "Advanced" in the watch space, it is usually defined as pioneering construction methods or pioneering materials.  This is not to be confused with "Complicated" which mean watches with functions that show more than the hours and minutes.  Seconds, dates, day displays are all complications.  Silicon parts would be "advancements."  

The 7135 is an extremely advanced movement for a mass produced movement.  It is a significant risk to introduce so many new parts on a watch all at once; as it means you have multiple failure points.  Historically most watch companies have introduced new technologies piece by piece and in gradual steps.  

The 7135 is endowed with multiple new advancements!  Syloxi is new in such an application (Rolex has technically introduced Syloxi back in 2014, but it's not the same).  The ceramic balance staff holder is new and further reduces friction.  The new double-wheel escapement has never been pioneered en masse before.  Five Hertz beat rate is also unusual for a Rolex time-only watch.  Eighteen to thirty-two new patents are directly attributed to the Land Dweller!  

Looking at the advanced watch companies with experimental technology; the Ulysses Nardin Freak had the double wheel escapement, some Freaks even had lab-grown diamond escapement parts, but none of the other attributes; no Patek Philippe Advanced Research piece has something like the 7135; perhaps the 10 Hz Breguet (Reference 7727) comes close, but no Breguet has incorporated so many of these technologies in one watch (the Breguet 10 Hz has silicon hair springs, magnetic pivots, and high beat, but not a double wheel escapement).  Some independents like Leberer, Frodsham, Journe's Optimum, have double wheel escapements but don't have other attributes the Rolex possesses.  And none of these are produced in scale by the thousands and tens of thousands per annum.  

All these features are very impressive.  But, what are the benefits?  Mainly expect to see impressive performance benefits; greater accuracy, faster shock recovery, across a wider temperature range (minor point since most watches aren't subjected to extreme temperatures), and very long service intervals.  Rolex didn't mention a service interval in the press release, but I would expect a very long interval.  The watch is rated by Rolex to have a -2/+2 second per day accuracy (the Rolex "Superlative" standard).  The watch is also rated by the COSC to meet COSC standards.  Accuracy guaranteed for five years from date of sale.  

It seems this Rolex 7135 movement is the most ADVANCED movement in the world!  Big congrats to Rolex!!!  While the average customer may not notice the technical details, it's still a tremendous achievement.  I look forward to the comments in the years to come, and in the decades to come, we will see if the service interval really is significantly lengthened.  


The ceramic balance staff holder is definitely a major advancement.  The smoothness of the ceramic is necessary to eliminate friction.  The ceramic itself is laser cut and laser polished for smoothness.  


Rolex has put in a double wheel escapement.  In silicon.  No less than seven patents are registered for this escapement wheel system.  



Big bravo to Rolex!  

About the Breguet Tradition Automatique Seconde Rétrograde Ref. 7727

The Rolex Cellini Time reference 7727 is part of the Cellini collection, which represents Rolex's more traditional and dress-oriented timepieces, distinct from its Oyster Perpetual professional and classic lines. This reference focuses on essential timekeeping, presenting hours, minutes, and seconds in a refined and understated manner, aligning with the Cellini's design philosophy of classic horology. It is designed to offer a sophisticated alternative within the brand's offerings, emphasizing elegance over robust utility.

This particular reference features an 18k Everose gold case, measuring 39 mm in diameter. It houses the automatic caliber 3132, a self-winding mechanical movement manufactured by Rolex. The watch is fitted with a domed sapphire crystal, contributing to its classic profile, and offers a water resistance of 50 meters. The movement provides a power reserve of approximately 48 hours, ensuring reliable timekeeping.

The Cellini Time 7727 appeals to collectors seeking a dress watch from Rolex that prioritizes classic aesthetics and horological tradition. Its Everose gold case and clean dial design make it suitable for formal occasions. The Cellini collection, including this reference, offers a different facet of Rolex's manufacturing capabilities, focusing on refined design and traditional watchmaking principles.

Why not Land-Lubber?

This thread talks about the strange naming choice... www.watchprosite.com

In any case, it’s an interesting watch… I like the case style

Glad they will do exhibition case back as well. However, like you suggest, I believe the movement details and advancements will be lost on many leaving most questioning the price differential with OP etc.

I typically get pretty excited about new movement advancements, but I don't find this movement very exciting. With the escapement design fundamentally requiring it to be a MEMS device, I can't help but find it more comparable to the gyroscope in my phone rather than a typical Swiss lever escapement that at least has the potential to have a human hand in its manufacturing (even if that is often not the case). I am also imagining (but probably wrong) that this must be extraordinarily cheap to prod

It really is A BIG DEAL. And when you think about watches with these things, they're typically fragile, very expensive, and not always reliable. For Rolex to have the confidence to debut this on such a mass market piece is a big deal. But, I also understand that when it comes to watches, these are antiquated objects, and you want something made in the old way. A lot of these silicon parts give a coldness to the medium. And they're also not about craftsmanship, as these things are always machine
