What people say

Owners + reviewers, side by side

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

Helgray Silverstone (Refurbished)

Owners widely praise the Helgray Silverstone (Refurbished) for its crisp printing, applied indices, legible date wheel, and solid pushers, noting an amazing fit and finish for the price and an attractive aesthetic. Some owners find the metal bracelet squeaks, and the 24-hour subdial is less desirable than sub seconds. One owner criticizes the thick case, downward-angled lugs that can dig into the wrist, and a crystal with noticeable edge effects. Overall, owners rate the Helgray Silverstone (Refurbished) highly for its impressive build quality and aesthetic appeal at its 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.
