Model reference: KA1F

I’m immediately trying to compare with my [high-end watches] and I honestly can’t say how they would be superior to this (on the topic of dials)

Celegin Treudd (ref. KA1F)

A professional diver’s watch

Treudd is Swedish for ‘Trident’ and is a so-called professional diver’s watch. It complies with the ISO 6425 standard which includes requirements for water resistance, illumination and other features. The name, Treudd, is a dedication to the Swedish Combat Divers and Coast Rangers, who wear a golden trident as their insignia. We therefore like to believe that Treudd is probably the toughest Swedish diver.

Since all print of the watch is in Swedish language, the water resistance on the dial is measure in Swedish fathoms (famnar) instead of meter. This is probably the first and only watch in the history to ever use this (obsolete) unit.

The first version, KA1F, is our so-called “founder’s limited edition” available in 100 numbered pieces.

Treudd is Swedush for Trident – a dedication to the Swedish Combat Divers and Coastal Rangers, whose insignia is a golden trident. The case back sports a detailed embossed Trident over a wave pattern.
All our watches come with a secondary strap. The Treudd (KA1F) has a dark blue two-piece nylon strap that matches and enhances the blue bezel.

Post-release note: All models and prototypes of our KA1F and KA1S Treudds have a small rotation of the dial versus the case. This originates from when we removed the crown guards of our original conceptual design leading to a small error in the 3D model that nobody noticed until we’d already produced and delivered the majority of the watches. Since the tilt has been there all along without us noticing, this is considered a feature and not a bug. As such, Celegin Precision Timing will not replace or refund any Treudd orders based on this. We may offer a case replacement in connection with servicing for those who’d prefer that.
