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.

TAG Heuer Connected Calibre E5

Owners widely criticize the TAG Heuer Connected Calibre E5 for its high price, with some finding its components and assembly not justified by the $2000 cost. Several owners report significant issues with battery drain, with Wear OS identified as a primary culprit, and some experience frequent bugs and software update problems, leading to regret over their purchase. One owner noted the lume on the mechanical module lasts only about five minutes. On balance, owners rate the TAG Heuer Connected Calibre E5 poorly due to its high price and reliability concerns.
