Behind the Innovative Design of the Land Dweller: Technology & Craftsmanship
Behind the innovative design of the Land-Dweller lies a world of technical brilliance that goes far beyond appearances. Focus in on the exquisite details that showcase Rolex’s remarkable achievements in watchmaking innovation.

Dynapulse Precision Lubrication
The Caliber 7135 is equipped with Rolex’s innovative Dynapulse escapement system, which differs from the traditional Swiss lever escapement found in other Rolex movements. Due to the way it functions, this escapement requires oil-based lubrication instead of grease.
Technicians apply the lubricant using ultra-fine bent needles, dispensing oil in quantities measured at the nanoscale. This meticulous process demands a unique assembly method: the entire escapement system is pre-assembled and lubricated on an external support before being installed into the movement.
This groundbreaking technique represents an entirely new manufacturing approach developed by Rolex’s in-house experts.

Dynapulse Escapement: Design and Structure
The components of the Dynapulse escapement system feature a number of patented innovations. One key patent relates to the design of the silicon intermediate wheel, which is unique in that both the gear teeth and the impulse blades lie on the same plane. This wheel serves a dual purpose: its teeth engage with the rest of the gear train, while also positioning and guiding the impulse rocker with precision.
Every element of the escapement has been meticulously engineered to ensure reliable and consistent performance. All silicon components are skeletonized to minimize inertia, which in turn reduces the energy required for meshing and movement.
Balance Staff: A Major Technical Challenge
The balance staff is crafted from exceptionally hard white ceramic. After precision machining, its surface is polished to the nanometer level. This ultra-smooth finish helps prevent damage or cracking upon impact, while ensuring minimal friction during operation. Advanced femtosecond laser technology is used to shape the staff, giving both pivots an ideal geometry that significantly enhances shock resistance.

Enhanced Paraflex Shock Absorber
Effective Shock Resistance
To accommodate the ceramic balance staff within the hairspring and balance wheel assembly, the Paraflex shock absorber has been optimized. The improved design features a highly flexible internal “double-cone” structure. The central jewel is crafted using a new patented process that blends cutting-edge technology with traditional craftsmanship. Both ends of the balance staff are equipped with the upgraded Paraflex shock absorbers, which include enhanced spring blades to ensure precise reset after impact. This system guarantees stable oscillation of the balance staff in all positions.

5 Hz Oscillation Frequency — Smooth and Steady
Thanks to the high oscillation frequency of the Caliber 7135, the Land-Dweller's seconds hand moves exceptionally smoothly. The movement beats at 5 Hz, meaning it ticks 10 times per second, 600 times per minute, and 36,000 times per hour. This high frequency allows the time display to measure up to 1/10 of a second precisely. The dial’s slightly angled flange features a printed minute track with markings accurate to half a second.
Concealed End Links — Compact and Durable
The robust concealed end links, patented by Rolex, are located between the lugs of the mid-case. This mechanism hinges the bracelet with a spring-loaded clasp less than one centimeter in length, which locks into the lug holes. Screws within the first hinged link secure the clasp to prevent rotation, enhancing durability. The first hinged link contains ceramic inserts to prevent premature wear.
Chamfered Bracelet Edges — Polished with Satin Sheen
A key aesthetic feature of the Land-Dweller is the chamfered and polished edges of the bracelet links. The mid-case edges are chamfered and polished to create continuous flowing lines that reflect light elegantly. To achieve this visual effect, Rolex developed a special manufacturing process with extremely high precision to chamfer the outer bracelet links.

High-Tech Matte Finish
Stylish Texture
The high-tech matte finish is distinguished by its striking linear texture and matte appearance. This finish is now introduced for the first time on Oystersteel, 18K Everose gold, and 950 platinum models. The matte surfaces on the case top and the outer links of the bracelet alternate skillfully with the polished chamfered edges and center links, perfectly highlighting the modern style of the Land-Dweller watch.

Chromalight Luminous Hour Markers
Radiant Glow
The Land-Dweller’s hour markers feature hollowed-out ends, creating a distinctive look. Achieving this design required modifying the usual Chromalight luminous material. This specialized lume is made by blending ceramic luminescent powder with a thermosetting polymer. Additionally, machining the hour markers and the luminous ends demands a material with exceptional strength.
