What people say

Owners + reviewers, side by side

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

CWC RN Quartz Divers Watch Mk.2, Matte Top

Owners widely praise the CWC RN Quartz Divers Watch Mk.2, Matte Top for its excellent matte case finishing, precise seconds hand alignment, and dial reminiscent of vintage military watches. The Mk.2 upgrades, including a sapphire crystal, improved lume, and a precise 120-click bezel described as perfection with no play, are consistently highlighted as significant improvements over earlier versions. One owner noted the quartz movement gained 8 seconds over several months. Overall, owners rate the CWC RN Quartz Divers Watch Mk.2, Matte Top highly for its solid construction, military significance, and terrific value.

Timefactors PRS-40

Owners widely praise the Timefactors PRS-40 for its unique, "badass" and rugged, futuristic design, with many highlighting the 12 o'clock crown as a distinctive and appreciated feature. The bead-blasted finish is noted to show light marks but resists deep scratches, and the sapphire crystal is considered good. While some owners find the 40.2mm case size acceptable, others describe the watch as large and wearing big, though it is noted to wear thinner than an automatic version. The fixed lugs necessitate the use of NATO straps, and the included strap is well-regarded. On balance, owners rate the Timefactors PRS-40 highly for its distinctive, bombproof design and unique crown placement at an accessible price point.
