Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Sinn EZM 3 S is praised for its robust build, Tegiment technology, and scratch resistance, making it a purpose-built tactical dive watch. Reviewers note its reliable Sellita SW200-1 movement, though its 38-hour power reserve is considered somewhat outdated. Overall, reviewers find the Sinn EZM 3 S to be a highly capable and durable tool watch.
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.
