What people say

Owners + reviewers, side by side

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
