Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Horage Decaflux is praised for its innovative in-house K3 movement, featuring a silicon escapement and a 96-hour power reserve, along with chronometer certification and a slim 9.98mm profile. Reviewers note its tinted sapphire crystal, lightning bolt seconds hand, and bracelet with an integrated vibe and thin clasp. The watch is priced at CHF 2,750, with preorder pricing at CHF 2,500, representing a strong value for an in-house Swiss movement. Some reviewers find the lightning bolt seconds hand slightly too wide and note a direct design homage to the Rolex Milgauss. On balance, reviewers rate the Horage Decaflux highly for its technical innovation and value proposition at its price point.
Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
