What people say

Owners + reviewers, side by side

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

Horage Autark Tourbillon GMT

Owners widely praise the Horage Autark Tourbillon GMT for its Swiss-made tourbillon, platinum micro-rotor, and super-thin 9mm titanium case design, noting little less than premium feel in case and movement finishing. The dial features a sub-seconds, date, and power reserve indicator, powered by an in-house movement with a 60-hour reserve. Some find the sub-dial illegible and hour hands difficult to read quickly, while others note the stepped bezel is not to their taste and the micro-rotor can be loud. The bracelet's lack of taper is also flagged as a drawback. On balance, owners rate the Horage Autark Tourbillon GMT highly for its premium finishing and innovative technical features at its price point.

Spinnaker Dumas Automatic

Owners widely praise the Spinnaker Dumas Automatic for its attractive textured blue dial, applied indices, and well-finished case, noting its comfortable wearability due to a short lug-to-lug distance. Some owners flag the use of mineral crystal instead of sapphire and a bracelet with a learning curve and loose keeper. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetics and case finishing at its price point.
