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 LX line

Owners widely report the dial's blue-green sunburst is phenomenal, and the sapphire glass features blue AR coating. Some owners feel the high price limits discounts and sales, with one AD noting extremely low sales due to the cost. One owner reported DLC peeling off a two-week-old watch, and another noted quality control issues like bezel inserts and fallen second hands. On balance, owners consider the Seiko Prospex LX line a nicely built watch, though pricing led to poor sales and its discontinuation.

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.
