What people say

Owners + reviewers, side by side

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

Sternglas Berlin

The Sternglas Berlin is praised for its stylish Art Deco-inspired design and slim 38mm case, offering good value at $270 for newcomers to watches. One reviewer notes the Miyota GM02 quartz movement is accurate to ±20 seconds per month, but flags the included leather strap as squeaky and suggests an alternative. Overall, owners find the Sternglas Berlin a satisfying purchase for its aesthetic and price point.

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.
