Ressence Type 1 Slim

The Type 1 Slim is a new thinner version of the original Ressence Type 1 watch.

The genesis of the Type 1 Slim starts with the Ressence Orbital Convex System (ROCS), the unique in-house developed (and patented) horological unit featuring an ever-changing dial that continually orbit around one another.

The purpose is a more efficient way of telling time. Information is displayed on a single surface, much like words on a piece of paper, making for improved readability. This differs than that of a traditional watch, where the hands and dial are layered on one another producing an uneven viewing plane. Composed of 107 parts, the gears in the ROCS calculate the hours and day, taking only the minute as a reference from the movement.

First debuted in 2014, the Type 1 is still Ressence’s most stripped back watch to date. It differs distinctly from the rest of the collection in its visual balance of simplicity and complexity, one that ensures its aesthetic only continues to enrich over the years. The new case design is not a revolution but rather an evolution. Not only it is slimmer (11mm thick) – compared to the previous generation – but also resolutely more modern with its seemingly integrated strap. Lugs and case are in fact milled in one action from the same grade 5 titanium block.

The Type 1 Slim is manually set via a lever on its case back. The watch has no crown, the winding and setting mechanism being the case-back itself, for better ergonomics and allowing a left-right fit. It is all tactile curves, the domed sapphire glass extending to the very edge of the case – making the watch more sapphire than metal for greater readability.
