What people say

Owners + reviewers, side by side

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

Lum-Tec Combat Field

Owners widely praise the Lum-Tec Combat Field for its rugged build and excellent lume, with one owner highlighting the bronze case and California dial as special features. The DLC coating is considered durable, and the PVD finish offers a "pure sport" blacked-out aesthetic. Some owners appreciate the modern look and design elements like skeleton hands and a 9 o'clock crown, noting that the 43mm case wears smaller than its dimensions suggest. One owner experienced an issue with a chronograph second hand not aligning correctly, a common quartz chronograph problem. On balance, owners rate the Lum-Tec Combat Field highly for its robust construction and distinctive design elements.

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.
