Reviews

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

Bremont Altitude Chronograph

The Bremont Altitude Chronograph is noted for its improved Roto Click bezel, offering better smoothness and click precision. Owners observe faint marks on the case sides and back, along with strap wear. One review flags the "DANGER EJECTION SEAT" wordmark on the dial as a divisive design choice that deviates from the MB series' usual tone. On balance, reviewers find the Bremont Altitude Chronograph to be a well-built watch with a refined bezel action, though some find dial text polarizing.

Nezumi Studios Tonnerre

The Nezumi Studios Tonnerre is widely praised for its comfortable 38mm case, sharp finishing, and retro design, with many owners appreciating its quality and presentation exceeding expectations for its price point. The Seiko VK63 meca-quartz movement offers reliable accuracy, and the dial colors and textures are frequently highlighted as unique and attractive features, complemented by a good quality strap. Some owners find the chronograph sub-dial hands' chromatic arrangement for the 24-hour indicator to be an unnecessary aesthetic choice, and a few have expressed disappointment with customer service or found the chronograph's sub-dial alignment prone to issues. On balance, owners and reviewers rate the Nezumi Tonnerre highly for its compelling retro aesthetic and excellent finishing at its price point.

From video reviewers

The watch features a 38mm brushed stainless steel case that fits smaller wrists well. The 5 ATM water resistance is limited for a tool-oriented chronograph.
