What people say

Owners + reviewers, side by side

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

Formex Essence Fortythree

Owners widely praise the Formex Essence Fortythree for its comfortable wearability, excellent finishing for its price point, and a dial that plays well with light, with one owner noting the blue dial's variable appearance. The bracelet's micro-adjust system is functional, and the leather strap and deployant are considered exceptional. Reviewers highlight the watch's legible design and slim 10mm case, noting its significant value under $1,300. Some find the dial design derivative and the hardware-style logo out of place, while others consider the white dial stark. Consumer confusion exists regarding COSC versus non-COSC movement options. On balance, owners and reviewers rate the Formex Essence Fortythree highly for its luxury-level finishing and comfortable, value-driven design.

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.
