Help with this Elgin Valjoux 7736. Thoughts on a strap?

Hey all I recently received this watch in a lot and I love it. Beautiful condition, just needs servicing. As always with my watches I am struggling with what strap to buy for it. I definitely want a black and white rally but I don't know if I should go for the big or small holed variety. Does anyone have any thoughts? Also does anyone know when these were made? All I can find online is 1970s, are there any ads out there showcasing this piece?
