This adapter was specifically made for Casio G-Shock Master of G MUDMAN G9000 series.
It's one size that fits all. The strap inside the photo was 22mm. The maximum width supported by this adapter is 24mm. I would highly recommend 22mm - 24mm strap to be used with this adapter. * If you want this adapter made specifically fitting a smaller size such as 20,21,or 22mm, please write a note when you place an order. You can also order sizes more than 24mm just let me know.
**** This listing is only selling the adapter. Strap, springbar, and watch is not included.
