This Strapcode rubber strap features curved ends and integrated stainless steel end links to fit Seiko Speedtimer cases, including the SSC813 model. Made from vulcanised FKM rubber, this blue strap resists oils and acids while offering a durable feel on the wrist. It includes a brushed stainless steel clasp with micro-adjustment holes for a customisable fit.
This model does not feature quick-release bars. It is available in lug widths of 18mm and 20mm to fit your watch.
One tool, a spare set of spring bars, and every swap takes a minute.
