1950s style leather strap that feeds through leather pad. 18mm and 20mm styles differ slightly. Also available in extra-long length for larger wrists.

Regular length strap = 230mm end-to-end, 210mm to last hole.
Long length strap = 260mm end-to-end, 240mm to last hole.

Please note: Due to changes in the manufacturing process, these straps are no longer suitable for the standard G10 issue or GS Sapphire watches, as the leather is too thick to pass through the bars.
