The Pola 65 is more difficult to associate with straps, as the dial is very classic and elegant, and the strange combinatinos are to avoid.
With the 68, things are easier, indeed.
BUT, the most important, when you come to choose a strap, is to well know and understand the watch.
Then, the choice comes easier.
I still have to work a bit, but with these last straps, I got a very pleasant outcome.
To be followed...
Best, Sister.
