What people say

Owners + reviewers, side by side

The Baltic Aquascaphe MK2 is widely praised for its refined case design, improved lume with applied markers, and added crown guards, presenting a sharper and more purposeful neo-retro dive watch. Owners and reviewers highlight its updated technical and design elements, including a fully graduated sapphire bezel and two case size options (37mm and 39.5mm), all while maintaining a reasonable price point. Some find the design derivative or less cohesive than its predecessor, with one owner noting the long, straight lugs as a significant drawback, while others appreciate the dial texture and case profile. The Baltic Aquascaphe MK2 is powered by the Miyota 9039 movement with a 42-hour power reserve and offers 200m water resistance. Overall, owners and reviewers rate the Baltic Aquascaphe MK2 highly for its value and contemporary updates to a tool-watch heritage.

From video reviewers

The Baltic Aquascaphe MK2 features 3D Super-LumiNova indexes for improved legibility. A notable weakness is the lack of lume brightness.
