What people say

Owners + reviewers, side by side

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

Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package. Press images suggest the bracelet end links may appear disjointed. Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.

Studio Underd0g The Gimlet

Studio Underd0g The Gimlet is praised for its playful, layered dial construction featuring a textured sapphire disc over a luminous base, creating depth and animation, and its comfortable 38mm case dimensions. Owners note its attractive dial color and combination, though some find the design too similar to other models and question the aesthetic of the visible dial screws. The watch utilizes a reliable, tactile Sellita SW210-1 manual-wind movement. On balance, owners and reviewers rate Studio Underd0g The Gimlet highly for its unique dial construction and comfortable wearability.
