Reviews

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

Aigi Watches Gruvebus

Owners widely praise the Aigi Watches GRUVEBUS for its legibility and the unique coal-pressed dial motif, with some comparing its character to Grand Seiko. The watch features GTLS tubes for luminescence and a hardened steel 40mm case, powered by a Sellita SW200-1 automatic movement and offering 200m water resistance. Some owners report receiving the watch with a Miyota 9015 movement upgrade. One owner notes the Jubilee-style bracelet as a luxurious touch for a tool watch, while another finds the 40mm case size and 49mm lug-to-lug measurement to be chunky. On balance, owners and reviewers find the Aigi Watches GRUVEBUS to be a decent tool watch for its price, with its unique dial and legibility being key strengths.

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.
