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.
Owners widely praise the Oceaneva GMT Titanium Automatic Deep Marine Explorer 1250M for its exceptional value, robust titanium construction, and impressive 1250m water resistance, with one owner noting it has been fantastic for years. The watch features an uncommon mother-of-pearl dial option and BGW9 lume, powered by the reliable Seiko NH34 automatic GMT movement. It has been observed as a blend of design elements from established luxury dive and GMT watches, with a price point around $225-$299 depending on discounts. Overall, owners and reviewers rate the Oceaneva GMT Titanium Automatic Deep Marine Explorer 1250M highly for its rugged build and compelling spec sheet at its price.
