Question about Jay's 20mm Omega rubber strap?

[longshot]

i have a small credit from jay at silix from a part that did not fit and was thinking about using it to get a 20mm omega rubber dive strap?

i have both an old factory black SMP (modded) and a 42mm 4th gen P.O. i think i would be happy with the rubber strap on either one, and i'll just put the dimodell coronissimo that's been on the SMP on the other watch.

my question is: does jay's 20mm rubber omega strap fit the P.O. or the SMP? or is it a crappy fit on both? for $51 i'm hoping it's decent quality and that it will work well with no gapping on at least one of the two omegas?

has anyone tried jay's strap on both watches? opinions?

thanks!
