What people say

Owners + reviewers, side by side

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

Seiko 62MAS

The Seiko Prospex Sea 1965 Heritage Diver's Watch is praised for its vintage-inspired finishing, crisp bezel action, and build quality. Owners widely report the movement averages within +/- 10 seconds per day, though some note accuracy issues. The 40mm case size is considered by some to wear larger than expected, and the price point is a subject of debate, with some finding it too high and others fair. The watch features a 72-hour power reserve from the Caliber 6R55 movement, a 300-meter depth rating, and a box-shaped sapphire crystal. On balance, owners and reviewers appreciate the Seiko Prospex Sea 1965 Heritage Diver's Watch for its refined design and solid build quality, despite some reservations about its price and perceived size.

Vario 1918 Medic Brass

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.
