Mesh looks great on everything, the orange isn't quite as good on the SM300 as I was hoping... and sadly you CAN'T fit an Omega Mesh Strap on a Rolex 1680 submariner, the springbars are just too thick to fit through the mesh loops... and don't try to force it, because you will just end up coaxing it back out with pliers after it gets jammed half-way.

 

Surprisingly yes, the clasp on the mesh bracelet actually has springbars on the end of it, you can fit a 20mm leather strap, or any bracelet that has holes in the end of it onto the springbars and use it as normal.
