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.

Zelos Nova 37

Owners widely praise the Zelos Nova 37's spectacular 37mm dimensions and extremely light, thin wearability. The meteorite dial is frequently highlighted as a captivating feature, though some reviewers suggest simpler indices would improve legibility over the Arabic numerals. The watch is considered a considerable value at $1,999. On balance, owners and reviewers rate the Zelos Nova 37 highly for its excellent dimensions and dial execution at the price.

From video reviewers

The wafer-thin case and intricate dial textures are standout features. The quality of the stock leather strap is a shared concern. Reviewers differed on whether the 37mm or 38mm case size was more accurate.
