What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport Bronze

Owners widely praise the Glycine Combat Sub Sport Bronze for its exceptional thinness, comfortable proportions, and finishing, with many appreciating its unique, non-homage design and the potential for a developing bronze patina. Reviewers and owners alike highlight its excellent value below $500, noting features like a Swiss movement with hacking, sapphire crystal, 200m water resistance, and excellent bezel action. Some owners find the crown digs into the wrist, and the original strap or bracelet is frequently disliked. Lume quality and power reserve consistency are noted as areas for improvement by some. On balance, owners and reviewers rate the Glycine Combat Sub Sport Bronze highly for its impressive finishing and slim profile at its price point.

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.
