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.

Zelos Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.
