Reviews

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

Seiko SKX009

Owners widely praise the Seiko SKX009 as a desirable daily beater and a favored summer watch for its looks, comfort, and tool watch feel, with one owner noting an inexplicable quality that makes them choose it over more accurate watches. The unique Arabic date wheel and red strap are specific points of appreciation, and it was a forum favorite for first-time diver purchases. Some owners find the stock bezel insert "hideous" due to its second markers and Pepsi colors, while others chose the watch specifically for it. The Seiko SKX009 is noted as having been discontinued. On balance, owners rate the Seiko SKX009 highly for its enduring tool watch appeal and distinctive aesthetic, making it a beloved, albeit now discontinued, choice.

Squale 1521

Owners widely praise the Squale 1521 for its classic look and robust build, with specific mentions of its wearable 12.5mm thickness and refined case finishing. The 42mm case is noted by some to wear smaller, closer to 40mm, due to short lugs, feeling solid without being too large. However, opinions on the bracelet vary, with some finding it too flashy or stiff, and one owner reported moisture ingress after a shower due to a loose case back. The crown can be difficult to operate due to deep integration, and the 38-hour power reserve is considered old-school but reliable. Overall, owners rate the Squale 1521 highly for its classic design and wearability, despite some reservations about the bracelet and crown.
