Reviews

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

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.

STEELDIVE SD1974C

Owners widely praise the STEELDIVE SD1974C for its exceptional value and robust build, with multiple reports of successful deep dives and no water ingress issues. The watch features excellent lume, with one owner noting it glows red and another praising its all-night performance, though there is some confusion regarding the specific luminous material used. The 43.8mm case is described as wearing well due to its shape, and the knurling, bracelet polishing, and circular indices are highlighted as positive design elements. One owner found the glossy dial challenging for photography. Overall, owners rate the STEELDIVE SD1974C highly for its impressive value and reliable performance, especially considering its accessible price point.
