Personal items such as guitar straps, clothing and more from the likes of Chris Cornell, Dave Grohl, Krist Novoselic, Elton John and Iggy Pop will be donated to create a one-of-a-kind capsule collection of watches to benefit addiction recovery.

A portion of the proceeds from the collection, spearheaded by the Rock LTD Collection, will go to benefit MusiCares MAP Fund which will help aid addiction recovery treatment.

Cornell, who passed away on May 18 after a show with Soundgarden in Detroit, was a longtime supporter of MusiCares and agreed to donate the strap before his death.

Each watch is individually hand-numbered and features a custom case back with the name of the artist along with a certificate of authenticity. The line will be available later this year.
