Reviews

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm case, which some owners find wears well even on smaller wrists due to its lug design, outperforming some 40mm watches. One forum contributor notes the 40mm case is relatively compact for a 300m diver and is priced at $1375. A reviewer found the 40mm case comfortable. On balance, owners and reviewers appreciate the Bremont Supermarine 300M's wearable 40mm case size and comfortable wearability.

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.
