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 Automatic Divers Watch Mk.2

Owners widely praise the CWC RN Diver for its build quality, comfortable wearability, and classic design with desirable brand heritage, suitable for diving. Some owners consider it a favorite, appreciating its case wear and aging tritium as a classic replacement for previous military issue watches. However, a common complaint across multiple sources is the fixed spring bars, which limit strap options, and some find the watch overpriced for its features, particularly when compared to other military-style watches or when noting specific branding text. One owner wishes CWC offered a smaller diver size. On balance, owners rate the CWC RN Diver highly for its utilitarian capabilities and historical connection, despite concerns about strap versatility and value.

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.
