Ressence Type 11 Debuts In-House Werk RW-01 Movement With Patented ROCS Display System
Ressence Achieves Two-Decade Vision With First In-House Movement
Belgium-based watchmaker Ressence has unveiled the Type 11, a timepiece that represents the culmination of over 20 years of development. According to aBlogtoWatch, the Type 11 features the brand's first fully in-house designed movement, the Werk RW-01, which integrates the patented Ressence Orbital Convex System (ROCS) display technology directly into the caliber rather than using modular additions.

Patented Ceramic Bead Power Reserve Indicator
One of the most innovative features of the RW-01 movement is its novel power reserve indicator. Rather than using a traditional hand or disc, Ressence employs small colored ceramic beads that move along a spiral-shaped cavity. As the mainspring winds, yellow beads move clockwise, followed by white beads indicating a full charge. As power depletes, dark blue ceramic spheres take over the display.
This approach represents a significant departure from conventional power reserve mechanisms and demonstrates the brand's commitment to rethinking fundamental watchmaking complications through original engineering solutions.
Crownless Design With Titanium Winding Handle
True to founder Benoit Mintiens' original vision, the Type 11 eliminates the traditional crown. Instead, a fold-out titanium winding handle serves dual purposes: turning in one direction adjusts the time, while turning in the opposite direction winds the mainspring. The RW-01 features two mainspring barrels connected in series to achieve the 60-hour power reserve.
Frequently Asked Questions
What makes the ROCS display system unique?
The ROCS (Ressence Orbital Convex System) uses rotating discs-within-discs to display time, with the entire surface area being convex. Unlike traditional watches with fixed dials and moving hands, ROCS involves the dial elements themselves orbiting to indicate hours and minutes.
How does the RW-01 movement differ from previous Ressence calibers?
Previous Ressence models used existing third-party movements with ROCS modules added on top. The RW-01 is the first movement designed from the ground up to fully integrate the ROCS display system, resulting in a thinner profile and more elegant mechanism.
What materials are used in the Type 11 case?
The entire case is constructed from polished grade 5 titanium, chosen for its lightweight properties and durability. The watch weighs only 49 grams including the strap, making it exceptionally comfortable for extended wear.
Industry Impact
The Ressence Type 11 represents a significant milestone in independent watchmaking. By developing its own integrated movement system, Ressence joins a select group of manufacturers capable of producing complete in-house calibers. The brand's approach to mechanical innovation — particularly the ceramic bead power reserve display — offers a fresh perspective on complications that have remained largely unchanged for decades.
