The Rolex caliber 7135 is a high-beat automatic movement. This 3-hander with a date calibre is found in the new Land-Dweller watches introduced at Watches and Wonders 2025 on March 31, 2025.

Rolex calls the 7135 an evolution from the cal. 7140 found in the Rolex 1908.

With this new movement introduction, it is worth noting that the Land-Dweller is one of the few Rolex models to feature an exhibition style caseback.

In Rolex’s own words:

“Entirely developed and manufactured in-house, calibre 7135 operates at an exceptional rate of 5 hertz, or 36,000 beats per hour, an unprecedented frequency for Rolex. This enables it to measure time to one tenth of a second.

An evolution of calibre 7140, which drives the Perpetual 1908, the new self-winding mechanical movement delivers outstanding performance, particularly in terms of precision, power reserve, convenience and reliability. It also presents a particularly attractive design. Through the watch’s transparent case back, the sparkle of the cut-out oscillating weight in yellow gold can be admired, as well as the delicate Rolex Côtes de Genève decoration on the bridges.” –Source

Dynapulse Escapement:

The 7135’s big claim to fame is that it is Rolex’s first movement to feature the brand’s patented Dynapulse escapement.

High-Frequency:

The 7135 is a high-frequency aka high-beat movement beating at 36,000 vibrations per hour.

The math works out to 600 beats per minute. With this frequency, the second hand moves at 10 “ticks” per second for an ultra smooth sweeping effect.

In contrast, most Rolex watches have a beat rate of 28,800 bph, with the seconds hand moving at 8 ticks per second.

While most people would not be able to spot the seconds hand movements with the naked eye, the movement is capable of measuring more precise passage of time. This is assisted by the half-second markers on the Land-Dweller’s inner bezel.

Is a higher frequency better?
While many prefer a higher beat rate for a smoother seconds hand, other benefits are that a high frequency movement is less prone to timekeeping disruption from externals impacts and shakes. This is due to the escape wheel and lever being in contact with each other with less delay than a low beat movement – in other words, less chance of skipping a beat, meaning an increased average accuracy rating.

The faster beat also allows for more accurate regulating and results in shorter “jumps” of the second hand, making it possible to measure time within smaller increments. However, faster isn’t always better, and a high beat rate is more demanding and technically prone to more wear and tear.

Typically, the higher beat rate also means the power reserve runs down faster, but in the case of the Dynapulse system used in the 7135, it has the same 66 hours of power reserve as the 7140 which beats at 28,800 bph.

Time-Setting:

The crown on the 7135 has 3 positions:

• 0  (unscrewed but not pulled out) – Manual-winding mode.
• 1 (pulled out one click) –  Date setting mode
• 2 (pulled out two clicks) – Time setting mode

When setting the date, turn the crown in counterclockwise direction.

Time setting is safe to do in either direction.

Manual-Winding:

According to Rolex, it is not enough to just shake your watch to get it to start running. For optimal performance, you will want to “jump start” the movement by manually winding the crown in clockwise direction, for a minimum of 25 turns. This is not the number of turns to reach full power reserve, but it is the number recommended by Rolex when wearing your timepiece from a stopped position. The movement of your wrist will do the rest of the word to wind the movement and keep it going. Don’t forget to screw the crown back in!
