The community take
Owners talk.
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.
