What people say

Owners + reviewers, side by side

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

Seiko Prospex Rotocall

Owners widely praise the Seiko Prospex Rotocall for its charismatic retro design and comfortable 37mm size, with many appreciating its space-faring heritage. However, multiple sources criticize its price point, suggesting it is too high for an all-digital quartz watch with features like a stamped clasp, mineral crystal, and standard quartz movement. Some owners also note drawbacks such as a flimsy battery mount and split pin bracelet construction. On balance, owners and reviewers find the Seiko Prospex Rotocall visually appealing and a faithful re-release, but its value proposition is frequently questioned due to its price.

Vario 1918 Trench Brass

Owners widely praise the Vario 1918 Trench Brass for its attractive, precisely made dial and case, with the evolving brass patina noted as a positive feature. The bund strap is considered comfortable and well-fitting by some, though others find it stiff and short for larger wrists. The lume is considered poor. The Miyota 82s5 movement is described as adequate, with accuracy ranging from about -10 seconds per day to simply running slow. On balance, owners rate the Vario 1918 Trench Brass highly for its fantastic looks and the unique character of its brass case.
