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.

Sugess Tourbillon Master SU8230

Owners widely praise the Sugess Tourbillon Master for its stunning enamel dial and impressive finishing at its price point. Accuracy figures vary, with one owner reporting -12s/day and another +6 to +11s/day. Caveats include a cumbersome winding crown, limited 50m water resistance, a 21mm lug width, and a non-hacking movement, with one owner noting a power reserve around two days and noticeable resistance when winding. On balance, owners rate the Sugess Tourbillon Master highly for its visually striking dial and finishing, which significantly elevates its perceived value.
