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 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.

DOXA SUB 300T

Owners widely praise the DOXA SUB 300T's functional and distinctive design, with reviewers highlighting its historical visibility and robust build. Legibility is consistently noted as excellent, with reviewers appreciating the functional no-decompression bezel and distinct hand shapes. The watch's accuracy is reported as good, with one owner seeing a 3-4 second daily gain, though the 38-hour power reserve is considered underwhelming by some at its price point. Criticisms include a stamped clasp that feels out of place and a bezel that may have lateral movement. The 42.5mm case is described as substantial and heavy, appearing larger due to extra width and making it unsuitable for dress shirts, a trade-off for its 1200-meter water resistance. On balance, owners and reviewers rate the DOXA SUB 300T highly for its unique design and robust dive watch capabilities.
