What people say

Owners + reviewers, side by side

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

Shiro Kara Daibāzu: Hulk SUB

Owners widely praise the Shiro Kara Daibāzu: Hulk SUB for its dial printing, date wheel, and bezel action. One owner confirmed the watch remained waterproof after five days. However, some owners report minor issues such as a slightly off-centered 12 marker or dissatisfaction with bracelet quality, while another felt the crystal was not the best but still looked great. Overall, owners rate the Shiro Kara Daibāzu: Hulk SUB highly for its strong dial and bezel presentation at the 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.
