What people say

Owners + reviewers, side by side

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

RZE Endeavour

The RZE Endeavour is widely praised for its exceptionally lightweight and comfortable titanium case, enhanced by an ULTRAHex coating for durability. Owners and reviewers highlight its striking dial, excellent lume, and the practical inclusion of a toolless adjustable clasp. The watch is noted for reliable timekeeping, with accuracy reported between +1 and +6 seconds per day. Some find the hands and indices slim, and one owner desired better contrast on the bezel's zero marker. The RZE Endeavour offers a value proposition with its 200m water resistance and Seiko NH38A movement. Overall, owners and reviewers highly rate the RZE Endeavour for its comfortable, lightweight titanium build and vibrant dial options.

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.
