Traditional Craftsmanship
The Seichu technique used on the Seiko L0N3015J0 mirrors the artistry historically used to braid heavy decorative cords for securing traditional Japanese kimono sashes (obijime). This unique structure gives the fabric vastly superior tensile strength, resistance to UV degradation, flexibility, and comfort compared to standard nylon NATO straps.

  • OEM Seiko...Genuine Original Part
  • Dark Blue in color...looks black from afar
  • Whenever the Distributor-Supplier pair the strap with the #C200FS FAT springbars, I will make sure to includes them with the sale. However, if the distributor do not include the springbars, then I am at the mercy of shipping only the strap as shown.
