Reviews

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

ARES GMT Global Mission Timer

Owners widely praise the ARES GMT Global Mission Timer for its comfortable rubber strap, compelling internal 24-hour rotating bezel, and welcome GMT complication for travel. The watch's color combination is noted as a conversation starter, and enthusiasts appreciate its long-lasting battery and the 10 o'clock crown position. Accuracy is reported around +4 seconds per day. However, multiple owners report significant difficulties contacting the company for customer service and resolving issues, with some watches arriving with case markings or not as described. Overall, owners rate the ARES GMT Global Mission Timer highly for its travel-ready complications and comfortable wearability, despite significant customer service challenges.

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.
