The Seiko Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition (ref. spb509j1) is an automatic diver watch, with a 42mm stainless steel case, 13.3mm thick, powered by the 6R54 movement and a 72-hour power reserve. Water resistance is rated to 300m, under a sapphire crystal. Manufacturer MSRP is $1,750.
The Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition features a 40mm case, 300m water resistance, and a 72-hour power reserve from the Calibre 6R55 movement, with a new grey bezel insert and a wave-patterned silvery-white dial. Owners find the watch attractive and the large case wears well without feeling bulky. However, some consider the price of €1900 for a 6R54 movement with an accuracy of +25/-15 seconds per day to be too high, and the production run of 6000 units is not seen as a true limited edition. Overall, owners find the Prospex Sea Seiko Diver’s Watch 60th Anniversary Limited Edition aesthetically pleasing with good wearability, but express concerns regarding its value proposition and movement accuracy for the price.
