Here's an interesting one for you to consider. A blue Sumo pre Prospex with a ceramic bezel, MM300 hands (fixing my top two beefs with the Sumo), Strapcode Jubilee, MM300 adjustable clasp, also comes with the original seiko bracelet and a Borealis Isofrane style rubber strap. Running as it should.

Asking $500 I'll cover the shipping and PayPal fee's in the CONUS.
