Reviews

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

Dryden Chrono Diver Series 1

The Dryden Chrono Diver Series 1 is a 42mm mechaquartz chronograph with a sapphire crystal and 100m water resistance. Owners note that the chronograph hand may not reset perfectly to zero, a characteristic of the VK63 movement. The case features polished chamfers on the upper lugs, and the watch utilizes Swiss Superluminova BGW9. It has been listed for sale at prices ranging from $150 to $255 and includes two straps. Overall, owners appreciate the Dryden Chrono Diver Series 1 for its classic design and value, despite the common VK63 chronograph reset quirk.

From video reviewers

The Seiko VK63 mechaquartz movement is a shared strength, noted for its instant reset and sweeping chronograph hand. The bezel action and water resistance were considered standard for the price point.

Undone Tachikoma

Owners widely report the Undone Tachikoma is a great purchase at its price point. However, some commenters feel the design lacks detailed anime references and find the price too high for an IP collaboration without a recognized watch brand. Overall, owners rate the Undone Tachikoma highly for its value, though opinions are split on its visual connection to the anime.
