Strap alternative for Swiss Army 25499/24499?

[DDT]

Hello all.  I recently acquired two (!) Swiss Army 25499 watches in an assortment of non-runners I purchased.  I have managed to get one running pretty easily; the other will likely require a new movement.  However, the issue is that neither one has a strap, and the strap configuration is a bit funky - originally a notched silicone/rubber strap.  The notch is about 15mm, the outer band 23mm.  Sourcing an original band for these is well-nigh impossible, as they haven't been produced since (I believe) 2009, and nothing else has the same band.   (See image for original configuration)

My question is, does anyone have a good suggestion as to what might be a source for a workable, decent-looking alternative?  A 15mm strap is just going to be way too small (and likely uncomfortable); nobody seems to make a notched band in 15/23, and I'm not sure the angles in the case are quite 90 degrees, so fit would be fiddly.  I have considered a bund strap, but can't even find one of these for 15mm lugs...

 

Thanks for any ideas!

I would buy a normal silicone strap and cut the sides out. Should be easy enough.

Cousins have a good selection of silicone straps, but not 23mm. They have 22mm and 24mm and cheap, so no great loss if you mess up !

I think something without the stitching would look better and be easier to cut.

Thanks, definitely a possibility.
