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.

Tornek-Rayville Blakjak 12-hr GMT

The Tornek-Rayville Blakjak 12-hr GMT is a 42.5mm stainless steel watch featuring a DLC-coated bezel, sapphire crystal, and a matte black dial with 12- and 24-hour scales. It is powered by a Seiko SII NH36 automatic movement, offering a 41-hour power reserve, and boasts 200 meters of water resistance. The dial includes a day/date complication and Super-LumiNova BGW9 lume. Overall, owners and reviewers highlight its robust build and functional military-inspired design as key strengths.
