Product Detailed Description

ZF Factory Richard Mille RM 61-01 Yohan Blake 42.7mm Ceramic Watch

The ZF Factory Richard Mille RM 61-01 Yohan Blake combines a 42.7mm ceramic case with a black ceramic bezel, skeletonized dial and RMUL2 manual-winding mechanical movement.

This configuration provides hours, minutes and central seconds, while the openworked dial exposes additional mechanical and structural elements beneath the hands.

A sapphire crystal with anti-reflective coating protects the dial. A natural rubber strap and titanium folding clasp complete the sports-oriented configuration, while the supplied water-resistance specification is listed at 50 meters.

42.7mm Ceramic Case

The RM 61-01 Yohan Blake features a 42.7mm ceramic case.

The ceramic construction creates a technical exterior that complements the skeletonized dial and black ceramic bezel.

Ceramic provides high resistance to everyday surface scratches and helps maintain the defined appearance of the case during regular wear.

Despite its high surface hardness, ceramic should still be protected from strong concentrated impacts against hard objects.

Actual wrist presence will depend on the overall case geometry, thickness, strap adjustment and individual wrist size.

Black Ceramic Bezel

The watch features a black ceramic bezel surrounding the sapphire crystal.

The dark bezel creates a clear visual frame around the skeletonized dial while maintaining the technical material character of the RM 61-01.

Ceramic offers high resistance to everyday surface scratches, although strong concentrated impacts should still be avoided.

RMUL2 Manual-Winding Movement

The ZF Factory RM 61-01 Yohan Blake is equipped with an RMUL2 manual-winding mechanical movement configuration.

The supplied functions include:

Hours
Minutes
Central seconds

Unlike an automatic movement, this configuration requires periodic manual winding through the crown.

When winding the watch, turn the crown gently and progressively. Once noticeably increased resistance is felt, avoid applying excessive additional force.

Mechanical performance can vary according to movement regulation, winding condition, temperature, resting position and individual wearing habits.

Central Seconds Display

Running seconds are displayed through a central seconds hand together with the primary hour and minute hands.

This three-hand arrangement provides the essential time indications while allowing the skeletonized dial and visible mechanical architecture to remain prominent.

The moving central seconds hand also provides a direct visual indication that the mechanical movement is operating.

Skeletonized Dial

The RM 61-01 Yohan Blake features a skeletonized dial.

Instead of using a conventional solid dial surface, the openworked construction exposes additional mechanical and structural elements beneath the hands.

This layered architecture creates visual depth and allows the internal structure to become an important part of the overall design.

The skeletonized layout also complements the technical appearance of the surrounding ceramic case and bezel.

Sapphire Crystal with Anti-Reflective Coating

The dial is protected by a sapphire crystal with anti-reflective coating.

Sapphire provides excellent optical transparency and high resistance to everyday surface scratches.

The anti-reflective treatment helps reduce surface glare and improves visibility of the hands and skeletonized dial details under different lighting conditions.

Strong direct impacts against hard objects should still be avoided.

Natural Rubber Strap

This configuration is paired with a natural rubber strap.

The flexible construction complements the sports-oriented character of the ceramic case while providing a comfortable alternative to metal or leather strap configurations.

Natural rubber is practical for regular wear and can be cleaned relatively easily after exposure to perspiration or everyday moisture.

Correct strap adjustment helps keep the 42.7mm case stable and comfortable on the wrist.

Titanium Folding Clasp

The natural rubber strap is secured using a titanium folding clasp.

Titanium provides a lightweight metallic component that complements the sports-oriented construction of the watch.

The folding mechanism keeps the strap sections connected when opened and provides a practical closure system for regular wear.

The clasp and strap attachment points should be inspected periodically for excessive wear, damage or looseness.

50m Water-Resistance Specification

The supplied ZF Factory specification lists the RM 61-01 Yohan Blake with 50 meters of water resistance.

Actual water resistance depends on the condition and assembly of the crown, seals, crystal, caseback and other components.

A stated 50m specification should not automatically be interpreted as confirmation that every individual watch has independently passed a pressure test to that depth.

Professional pressure testing is recommended before intentional water exposure.

Wearing and Care Advice

Wind the RMUL2 manual-winding movement gently through the crown. Avoid applying additional force once noticeably increased winding resistance is felt.

Clean the ceramic case and black ceramic bezel gently using a clean, soft microfiber cloth.

Although ceramic provides high resistance to everyday surface scratches, avoid dropping the watch or exposing the case and bezel to strong concentrated impacts.

The natural rubber strap can be cleaned gently with a soft damp cloth and should be dried thoroughly afterward.

Avoid prolonged exposure of the strap to aggressive solvents, perfumes and strong chemical cleaning products.

Protect the mechanical movement from heavy impacts and strong magnetic fields.

Check the titanium folding clasp and strap attachment points periodically to ensure they remain securely connected.

Professional pressure testing is recommended before relying on the supplied 50m specification for intentional water exposure.
