Bremont ArgyllevsSeiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

The Bremont U-2 JET is praised for its exceptional accuracy, running between +0 and +1 seconds per day. It features a black DLC-treated steel case with a knurled aluminum mid-section and a smoked sapphire display caseback. The dial incorporates hash marks and Arabic numerals with tinted lume, complemented by heat-blued steel hands. The inner timing ring is bi-directional and operated by a crown at 4:00, which is described as satisfying to use but awkward on the wrist. Overall, owners and reviewers highlight the Bremont U-2 JET's precise timekeeping and distinctive case construction.

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.
