What people say

Owners + reviewers, side by side

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

Sternglas Kanton

The Sternglas Kanton is praised for its refined Bauhaus-inspired design, featuring a silver-plated dial and luminous hands and dots for excellent legibility. Owners and reviewers highlight its comfortable 39mm case size, measuring 10mm thick, and the visible STP 1-11 automatic movement through a sapphire crystal case back. Accuracy figures vary, with one source noting +15 seconds per day, while another suggests improved accuracy over previous models. Overall, owners and reviewers rate the Sternglas Kanton highly for its blend of Bauhaus design and Swiss precision at an affordable 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.
