Ressence Unveils Type 10 'Dark Night': First Oil-Filled Watch with In-House Movement

Key points

• The Type 10 'Dark Night' is the first Ressence watch to combine the proprietary RW-04 movement with an oil-filled ROCS display module.
• The watch features a 41.5mm Grade 5 titanium case with a deep blue DLC coating and a matching rubber strap, limited to 100 pieces.
• The RW-04 movement is an evolution of the earlier RW-01, featuring 252 components, two barrels, and a 60-hour power reserve.
• The design was developed over four years, focusing on hydrodynamic shapes and seamless integration to eliminate visual distortion from the oil-filled dial.
• The watch was unveiled at WatchTime New York on October 16, 2026, and will be available for purchase starting in November 2026.

Background

Ressence previously introduced its first proprietary movement, the RW-01, in the Type 11 at Watches and Wonders Geneva earlier in 2026. The brand had previously used oil-filled dials in models like the Type 7, but those relied on external movements. The Type 10 represents the first time the brand has integrated its own in-house movement with its signature oil-filled technology.

How outlets are covering it

Fratello Watches emphasizes the 'futuristic' aesthetic and the four-year development timeline, noting the design's hydrodynamic inspiration. Wallpaper* highlights the brand's philosophy of prioritizing user simplicity over mechanical complexity, framing the Type 10 as a distillation of Ressence's engineering ethos. Gear Patrol focuses on the technical separation of the oil-filled chamber and the air-filled movement chamber via a 0.1mm titanium membrane and micro-magnets, describing the design as 'organically inspired.' All sources agree on the 100-piece limit and CHF 45,000 price, but differ in emphasis: Fratello and Gear Patrol focus on the visual and technical novelty, while Wallpaper* contextualizes it within the brand's broader design philosophy.

Why it matters

The Type 10 'Dark Night' signifies a major milestone for Ressence, demonstrating the brand's ability to fully integrate its proprietary movement and display technologies. It moves the brand away from relying on external movement suppliers and showcases the feasibility of combining complex oil-filled optics with in-house mechanical engineering, potentially setting a new standard for high-end mechanical watch design.

What to watch

The Type 10 'Dark Night' will be available for purchase from Ressence starting in November 2026. The brand may continue to refine its in-house movements and oil-filled technologies for future releases, potentially expanding the use of the RW-04 or its successors in other models.
