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 GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
