Short NASA watchband (Space Shuttle issue)

This was the last version of the official NASA supplied watchbands, the type that was supplied as a discretionary "crew preference item" for Space Shuttle missions, such as this original below.

This Space Shuttle issued NASA watchband uses a Velcro brand hook and loop tape which is comfortable directly on the wrist. Wearable because it has soft woven-edges and not the stiff reinforced finishing required for military webbing.

• Width 19.5 mm for 20 mm lugs.  Also available are 21mm tapes for 22m lugs. 

• Mil-spec (Mil-T-5038) binding tape in current shade of Olive Drab, known as OD#7.

• All stitching with webbing strength mil-spec (V-T-295) nylon thread.

• Steel ring made from mil-spec (Mil-S-7720) aircraft grade 302 alloy stainless steel. This is the the hardest austenitic steels made and difficult to bend to the correct shape at this diameter.

• Delicately but clearly marked with P/N and S/N as per NASA-JSC marking specification for all space flown items inside the crew compartment.

• Length is 11.5 inches as per P/N SEB12100030-210, will fit wrists from 6 to 9 inches.
