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.

CWC G10 Fatboy-80 Quartz Re-Issue Watch

Owners widely praise the CWC G10 Fatboy-80 Quartz Re-Issue Watch for its 36mm size and comfortable, "chunky" wearability, with one owner calling it their "perfect watch." The bead-blasted stainless steel case, fixed spring bars, and acrylic crystal that scratches but buffs out are noted features. Some enthusiasts point out the dial's "T" marking alongside Super-LumiNova as a detail difference from originals, and one owner found the reissue's crystal magnified the dial more. The 50m water resistance is considered sufficient for its field watch purpose. On balance, owners rate the CWC G10 Fatboy-80 Quartz Re-Issue Watch highly for its comfortable wearability and distinct dial at its price point.
