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.

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.
