Sugess Seakors Tourbillon SE8004vsSeiko Prospex Sea 1965 Heritage Diver's Watch

Owners are impressed by the engineering of the Sugess Seakors Tourbillon SE8004 at its price point, with one owner noting the watch remains functional after three years of ownership. Some owners express concern over the potential difficulty and cost of servicing the hand-wound ST8007 movement, which offers a 40-hour power reserve and includes a 24-hour dial with day/night indicator and a date complication. Opinions are divided on the watch's size, with one owner finding the 40mm case optimal for a tourbillon while another describes it as humongous. Overall, owners appreciate the engineering of the Sugess Seakors Tourbillon SE8004, though servicing concerns and size opinions vary.

The Seiko Prospex Sea 1965 Heritage Diver's Watch is praised for its refined engineering and updated features, including a 300m water resistance and a 72-hour power reserve from the Caliber 6R55 movement in a 40mm case. Owners note its better build quality and interesting finishing with a mix of polished and brushed surfaces. The "Tranquil Teal" variant features a jewel-toned dial with a rippling-water pattern. However, some owners consider the price too high, and concerns exist regarding the accuracy of the 6R movements, with some reporting theirs run slow. One review notes a reflective dial that impacts legibility. On balance, owners and reviewers appreciate the Seiko Prospex Sea 1965 Heritage Diver's Watch for its refined design and improved specifications over previous generations, despite some reservations about movement accuracy and price.
