Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
Owners praise the Zelos Great White 1000m for its substantial 44mm size and robust build, with one owner highlighting the striking meteorite dial as a key feature. The watch is noted as a larger, more robust take on a familiar design, and one owner found the Arctic version to be a desirable, sold-out model. One reviewer humorously points out the absence of a helium escape valve on the 1000m diver. On balance, owners appreciate the Zelos Great White 1000m for its bold design and significant water resistance capabilities at its price point.
