What people say

Owners + reviewers, side by side

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

Gruppo Gamma Peacemaker Bronze Manual

Owners praise the Gruppo Gamma Peacemaker Bronze Manual for its character, with specific mentions of the dégradé green sandwich dial, matte black sandwich dial, and box-shaped sapphire crystal. The hand-wound ETA 6497-1 movement is described as a "dream" to wind, and one owner notes the Miyota 8N33 movement keeps outstanding time. The watch offers 200m water resistance and comes on a rubber or custom rally strap. Accuracy figures range from outstanding to +/-12 seconds per day with Sellita SW219-1 or ETA 6497-1 movements. On balance, owners rate the Gruppo Gamma Peacemaker Bronze Manual highly for its unique dial designs and the satisfying winding experience of its manual-wind movements.

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.
