What people say

Owners + reviewers, side by side

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

Beaufort Pulsatimer

The Beaufort Pulsatimer is praised for its solid manual-wind Sellita SW510M BH b movement and remarkable value, with one reviewer noting a 63-hour power reserve. Its 39mm case features dynamic, layered finishes and piston-style pushers, blending vintage dressiness with a robust chronograph design. Some find the optional beads-of-rice bracelet too much for its aesthetic. Overall, owners and reviewers rate the Beaufort Pulsatimer highly for its unique design and strong value proposition.

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.
