What people say

Owners + reviewers, side by side

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

Sugess Seestern Vintage S407 600T

Owners widely praise the Sugess Seestern Vintage S407 600T for its exceptional finishing, bracelet quality, and overall value at its price point. Reviewers and owners alike highlight the watch's fantastic looks and build quality, with one owner noting Seestern did a better job than the original inspiration. Some owners report a slight bezel back play and a clunky clasp, while others have no clasp complaints. Accuracy figures vary, with one owner seeing the watch run 2 seconds slow over 30 hours, and another noting a dial leaning slightly left. The watch measures 40mm wide, 14mm thick, and 48mm lug-to-lug, weighing 86g for the head and 163.4g total with the bracelet, leading some to find it heavy for wrists smaller than 7 inches. One owner questioned if the crown felt wobbly when winding or setting. On balance, owners rate the Sugess Seestern Vintage S407 600T highly for its outstanding build quality and aesthetic appeal relative to its cost.

Seiko Prospex Sea 1965 Heritage Diver's Watch

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.
