I’m looking for a straight rubber strap for my PANERAI PAM372.

What I’m specifically searching for is a completely straight 26/26 profile:
26mm at the lugs and also 26mm at the buckle. No taper at all.

Since the original buckle on the 372 is also 26mm, I think a straight cut would look much more balanced and “tool watch” like.

Most rubber straps I find tapered 26/22 heavily and somehow look too modern or sporty for the 372 and dosnt fit my 26mm buckle.

Does anyone know good sources for a true 26/26 rubber strap for Panerai PAM 372?
