What people say

Owners + reviewers, side by side

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

Oris Dat Watt Limited Edition II

The Oris Dat Watt Limited Edition II is praised for its comfortable wearability, unique green-to-blue gradient dial, and eco-minded symbolism. Reviewers note its handsome appearance and easy-wearing 43.5mm case with short lugs, which comes with both a steel bracelet and a vanilla-scented rubber strap. Some owners find the 38-hour power reserve of the Oris 743 caliber disappointing. The watch is rated to 300 meters and features a tungsten bezel, with one owner questioning the legibility of the circular date window. Overall, owners and reviewers appreciate the Oris Dat Watt Limited Edition II for its distinctive dial and comfortable design at its $3,200 price point.

Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is praised for its beautiful design and refinement over previous models, featuring vertically textured glacier-inspired dials. Owners, however, consider the €1500 RRP too high, suggesting a price closer to €900-€1000, noting the aluminum bezel insert instead of ceramic. Some owners report the 6R movement runs slow. On balance, owners find the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition beautiful and a refinement, but the price and aluminum bezel are points of contention.
