Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Eza 1972 Diver for its faithful vintage design and excellent value, with one owner noting it surpasses other watches in bezel action, crown comfort, thinness, and packaging, all at a significantly lower price. The watch is noted for its thin 39.6mm case and impressive accuracy, running at nearly 0 seconds per day. Some find the bezel action a bit stiff. Overall, owners rate the Eza 1972 Diver highly for its vintage aesthetic and exceptional value proposition.
The case finishing, with its mix of brushed and polished surfaces, is a notable strength. The price point of $995 USD is a point of contention, with one reviewer suggesting it may be high compared to competitors.
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.
