I want to change the strap on my Black Monster. Does anyone know of any rubber straps that take 2.5 mm spring bars (i.e "Fat Bars")?

I found the solution: use 1.78mm bars with 1.1mm ends (same size ends as fat bars) to facilitate the use of regular straps on a Seiko. Ebay seller twente(o) has them.
