SRPL11K1: red dial and bezel
The SRPL11K1 pairs a red dial and bezel with a stainless-steel bracelet. Seiko USA listed it at USD 595 at research time. The red colorway is the clearest visual distinction from the black SRPL13 and SRPL15.
SRPL13K1: black dial and bracelet
The SRPL13K1 has a black dial and bezel with a stainless-steel bracelet. Seiko’s UK store describes the design family as angular and recognizable, and says it combines Samurai and Shogun design cues. That is retailer product copy, not an independent review conclusion.

The SRPL15K1 combines a black dial and bezel with a black-coated stainless-steel case and silicone strap. Seiko’s 2024 announcement identifies the coating as titanium carbide.
