Does anyone out there have an SMP fitted with the 98000085 Omega Rubber Strap?

I am looking for information on how well it would fit a 19-19.5cm wrist.......i.e., is the buckle centred? Are there adjustment holes left? Photo's would be great!

Any mainly, I guess, do you feel it's worth the money? It's seems 'eye-wateringly' expensive as far as rubber straps go!

Thanks in advance :-)
