    Seiko Sumo - Bracelet - Diver Extension Removal?

    Don't hate me but I just don't find the diver's extension on the Sumo or Monster Bracelets comfortable on the wrist. Has anyone changed these out or can you recommend a 4-hole micro-adjustment replacement clasp that will work. Thanks.

    Even better if somebody might have an extra clasp they want to part with:)

    You can try to get a MarineMaster300 clasp from chronograph.com

    pretty pricey but very slick.

    Most any 18mm Seiko clasp (similar style) will work. I sourced a couple from Harold - Yobokies in the past in they worked well. Good luck !
