What people say

Owners + reviewers, side by side

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

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.

Seiko Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER's gorgeous, unique red dial and vintage-inspired design, finding it a sturdy and reliable everyday watch. Some owners, however, question the value proposition at around $700 for a solar quartz model, citing its 13-15mm thickness and the 24-hour subdial as drawbacks. Accuracy figures vary, with one owner reporting +1/+2 seconds per day, while another notes the V192 solar movement offers a six-month power reserve. Overall, owners and reviewers find the Seiko Prospex SPEEDTIMER a capable and versatile chronograph, with its striking dial and everyday wearability being the most frequently cited strengths.

From video reviewers

The Seiko Prospex SPEEDTIMER's solar movement provides reliable power without battery replacements and accurate timekeeping, with a claimed accuracy of ±15 seconds per month. A notable trade-off is the watch's slightly thicker profile and somewhat lacking lume brightness. Reviewers disagree on whether the bezel action is smooth and clicky, with one reviewer praising it and the other not mentioning it.
