This Seiko SRP639K1 is one of the Seiko watches produced under the Prospex line to cater to those whose sports require watches with truly professional specifications. The watch is fitted with a stainless steel shroud that provides a distinct appearance apart from functioning as a hard shield for the body of the watch.

The steel shroud is removable and replaceable, which would also enhance the future modification potential of this watch. The timing bezel of this piece is coated with black plating coupled with the yellow-themed timing indicator and hands that look truly impressive. The watch is rated 200M for its water-resistant and the hands and indexes are filled with a tremendous coat of luminous paint that will shine throughout the night or during deep water diving.

This Tuna comes on an original rubber Seiko strap and an extra Miltat steel Engineer Bracelet!
