What people say

Owners + reviewers, side by side

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

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised as an excellent gateway watch, offering great value with a solid build and powerful lume. Owners widely report that the NH36 movement's accuracy is a "luck of the draw," with official specs allowing up to +/-40 seconds per day, though many experience +/-5 to 10 seconds. Some owners note the lack of a screw-down crown and 100m water resistance, while others highlight its ISO 6425 compliance, 200m water resistance, and screw-down crown as superior tool watch features. Some owners find the original SKX models heavier and bulkier than newer lines, while others praise its iconic, tough, and rugged dive watch design and proven durability. On balance, owners and reviewers rate the Seiko 5 Sports SKX series highly for its iconic, durable dive watch design and strong value proposition.

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.
