The Ressence Type 1 | family history
The Type 1 is Ressence's entry point: no crown on the case, a ROCS display module that converts the traditional hand layout into co-axial rotating discs, and a titanium case that winds and sets via the caseback. It is a legitimate rethink of how a dial can display time rather than a visual exercise.
Ressence’s entry line: the crown-less titanium case with the ROCS 1 module, wound and set via the rotating caseback. No oil-fill; the discs orbit visibly on the dial-side. The Type 1° Round (2023) is the modern reference, on a customised ETA 2892 base.
2011 · Type 1 launch
Ressence launched the Type 1 in 2011 as the first production watch with the ROCS (Ressence Orbital Convex System): a module of seven discs that display hours, minutes, seconds, and day as rotating fields rather than traditional hands. The case has no crown; winding and setting is done via a rotating caseback mechanism. The base movement is a customised ETA 2892-A2.

2023 · Type 1 Round
The Type 1 Round (2023) is the current reference: a 42mm grade-5 titanium case, ROCS 1 module with the same crownless architecture, and a refinement of the caseback winding system that improved reliability over earlier Type 1 variants. The movement base remains the ETA 2892 family, extensively modified by Ressence for ROCS integration.
How to read this family
Two honest questions for any Type 1 buyer:
- Type 1 or Type 3? The Type 1 is the dry-case variant; the Type 3 is oil-filled. The Type 3 creates a more dramatic visual (the discs appear printed on the underside of the crystal) but adds maintenance complexity. The Type 1 is easier to service and the better starting point for a first Ressence.
- Is reading the time intuitive? The ROCS display takes a week to adapt to. After that, most owners report reading it as fast as a conventional dial. If you frequently glance at your watch in low-light situations and are not interested in adapting, the Type 1 is not the right watch.

Which ref to buy
The Type 1 is Ressence's entry-level reference and the clearest expression of the brand's ROCS (Ressence Orbital Convex System) philosophy: all subsidiary dials rotate around a central hub on a convex sapphire crystal, creating an oil-filled depth illusion. No traditional hands -- satellite discs track time, minutes, and seconds simultaneously.
- 1Open
Type 1 -- the most legible entry into the Ressence system, the design concept at its clearest.
- The case for it:
- The ROCS display is unlike anything else in watchmaking. Satellites that indicate time, minutes, and seconds simultaneously, all co-planar under a convex lens, filled with oil for a depth effect. The Type 1 is the version where the concept is cleanest and most immediately readable.
- Consider instead if:
- Ressence is a small independent brand with a short track record. Service network is limited. The oil-filled display, while beautiful, requires specialized service that is not widely available.
