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.

DOXA SUB 300T

Owners widely praise the DOXA SUB 300T's functional and distinctive design, with reviewers highlighting its historical visibility and robust build. Legibility is consistently noted as excellent, with reviewers appreciating the functional no-decompression bezel and distinct hand shapes. The watch's accuracy is reported as good, with one owner seeing a 3-4 second daily gain, though the 38-hour power reserve is considered underwhelming by some at its price point. Criticisms include a stamped clasp that feels out of place and a bezel that may have lateral movement. The 42.5mm case is described as substantial and heavy, appearing larger due to extra width and making it unsuitable for dress shirts, a trade-off for its 1200-meter water resistance. On balance, owners and reviewers rate the DOXA SUB 300T highly for its unique design and robust dive watch capabilities.
