What people say

Owners + reviewers, side by side

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

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.

Zelos Spearfish Dual Time

Owners widely praise the Zelos Spearfish Dual Time for its attractive design and the well-executed big date complication. The watch is described as a non-attention-seeking option that looks awesome, with a thickness of 12mm including the crystal and 10mm without. One owner found the $1900 price tag too expensive and uncharacteristic for the brand. On balance, owners rate the Zelos Spearfish Dual Time highly for its attractive design and the well-executed big date complication.
