Reviews

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

Orient AC0Q-40 Diver Watch

Owners praise the Orient AC0Q-40 Diver Watch for its value, sapphire crystal, and durable build quality, with many appreciating the 39.9mm case size for its smaller, trendy appeal and the raw steel bezel for a vintage look. The bracelet features folded end links, and while the in-house automatic Orient F6722 movement is considered a good workhorse, the watch is not ISO certified for diving, though suitable for swimming. Unless a purple dial is specifically desired, other color options are recommended. On balance, owners rate the Orient AC0Q-40 Diver Watch highly for its appealing design and value proposition in a compact package.

Thorn Titanium 39mm Automatic Dive Watch

Owners widely praise the Thorn Titanium 39mm Automatic Dive Watch for its exceptional lightness and comfort due to its titanium construction, with many highlighting the impressive finishing and the "game-changer" tool-free bracelet adjustment system. The lume is also frequently called out as superior. However, some owners find the watch wears a little small, and one owner returned it due to a ghost-date issue and the watch stopping once every 24 hours, with another reporting the watch stopped when the seconds hand reached 60. The design is described by one owner as somewhat uninspired, aside from the custom dial, due to common mod parts. Overall, owners rate the Thorn Titanium 39mm Automatic Dive Watch highly for its wearability and bracelet system.
