Seiko Prospex Sea 1965 Heritage Diver's WatchvsVario 1918 Medic Brass

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.

Owners widely praise the Vario 1918 Medic Brass for its crisp enamel dial, easy-to-read numerals, and cathedral hands, noting the brass case develops an attractive patina over time. However, the soft brass scratches easily, and one owner found the lume to be poor. Accuracy varies, with one example running slow by about 10 seconds per day and another owner deeming the Miyota 82s5 movement just okay. On balance, owners rate the Vario 1918 Medic Brass highly for its unique dial and the evolving character of its brass case.
