Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Aigi Watches ARCTIC DIVER is considered a decent value for its Kickstarter price, featuring a Seiko NH35 movement and 200m water resistance. However, its 41mm case size and 49mm lug-to-lug are described as chunky by some owners, and there are questions about the long-term viability of a Kickstarter brand. Overall, owners view the Aigi Watches ARCTIC DIVER as a solid watch for its price point, with its value proposition being a key draw.
Owners widely praise the Fortis Marinemaster M-40 for its gorgeous appearance and strong wrist presence, noting its impressive lume. The watch comes with a bracelet and three rubber straps, including a deployant buckle. On balance, owners rate the Fortis Marinemaster M-40 highly for its aesthetic appeal and comprehensive strap package.
The watch's Swiss Made construction and robust design are consistently praised. Reviewers noted the bracelet as a potential point of contention.
