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 Seiko Prospex LX line's finishing is a step up from other models, with a case that sits well on the wrist, and some praise the green sunburst dial with blue anti-reflective sapphire crystal as phenomenal. However, owners note the high MSRP limited sales, with some desiring smaller cases and a reduced price, and others experienced quality control issues such as detached second hands and peeling DLC coating, leading to concerns about fragility. On balance, owners feel the Seiko Prospex LX line was discontinued due to pricing that alienated its target market, despite its attractive dial.

Tornek-Rayville Blakjak Time-elapse

The Tornek-Rayville Blakjak Time-elapse is a rugged, dive-capable field watch, an evolution of a 1990s military concept. It features a 42.5mm stainless steel case, a sapphire crystal, and a Seiko NH36 automatic movement with a 40-hour power reserve. The dial is busy but functional, and the watch features Super-LumiNova BGW9. On balance, reviewers note the Tornek-Rayville Blakjak Time-elapse is a modernized military watch with robust dive capabilities.
