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.

DOXA SUB 300

The DOXA SUB 300 is widely praised for its wearability and vibrant color options, with reviewers noting its compelling charm and modern updates like improved lume and a meter-based bezel. Owners report the DOXA SUB 300 wears comfortably, with its cushion case and beads-of-rice bracelet contributing to a smaller perceived size. The COSC-certified ETA 2824-2 movement is noted for its accuracy, with one owner seeing it gain only +1 second in three days. However, some owners flag issues with the bracelet's end links sticking out and a sharp clasp edge, while one reviewer found the lume to be a disappointment. The polished bezel surface is also noted as prone to scratches. Overall, owners and reviewers rate the DOXA SUB 300 highly for its wearability and distinct design, despite some minor finishing concerns.
