What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Horage Decaflux

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.

Sugess Seestern S456 GMT

Owners widely praise the Sugess Seestern S456 GMT for its excellent case finishing, deep blue sunburst dial, and crisp indices, with one owner rating the overall fit and finish 9.5 out of 10. The watch is noted for its legibility, strong lume that lasts about 4 hours, and accurate timekeeping around -4 seconds per day, with easy GMT hand adjustment. Some owners report issues with a loose or friction-based unidirectional bezel, while others find theirs tight and prefer a bidirectional GMT bezel. The sapphire crystal is described as clear and flat by some, but others find it very reflective with AR coating that could be improved. Sizing is generally considered good at 39mm with a 46mm lug-to-lug and 12mm thickness, though one owner expresses concern about its 49mm lug-to-lug and 41mm bezel diameter. Overall, owners rate the Sugess Seestern S456 GMT highly for its impressive finishing and dial at its price point.
