What people say

Owners + reviewers, side by side

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

Baltic Aquascaphe MK2

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. Reviewers disagree on the optimal case size, with one reviewer noting a 41mm stainless steel case is comfortable for everyday wear, while the other mentions 37mm and 39.5mm case sizes are available.

Longines PrimaLuna

Owners widely praise the Longines PrimaLuna for its stylish, understated design and comfortable 26.5mm and 34mm case sizes, with some preferring the quartz for its lower maintenance and others the automatic for its craftsmanship. The automatic movement, an L899.5 or Caliber L899, offers a 72-hour power reserve and exhibits consistent accuracy averaging a loss of 1.3 seconds per day in testing, though it runs 3-4 seconds slower on the wrist. The redesigned collection features a curvier case with contemporary lug integration and is available in steel or bi-metal. On balance, owners and reviewers appreciate the Longines PrimaLuna for its elegant styling and reliable automatic movement, though some find its brand prestige and design less compelling compared to certain luxury alternatives.
