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.

Spinnaker Croft 39 GMT

Owners praise the Spinnaker Croft 39 GMT for its colorful design, NH34 GMT movement, and reasonable price, noting high-standard manufacturing on the case, bezel, and bracelet. One owner finds the 43mm case and 51mm lug-to-lug dimensions too large for the design, preferring a 39-40mm case size. A potential issue with the lume was noted by one user. On balance, owners value the Spinnaker Croft 39 GMT for its attractive design and build quality at its price point, though sizing is a point of contention for some.
