Seiko Turtle & Sumo Strap Size — 22mm Curved End
Seiko Turtle & Sumo Strap Size — 22mm, Curved Ends Match
The Turtle (SRP7xx/SRP6xx) and Sumo both take 22mm straps. Their cushion cases have a distinct silhouette — curved-end 22mm straps and bracelets match the case lines, while straight ends leave a small gap that many owners accept for NATO and rubber.
