Good luck with your choice. I definitely prefer the orange strap and the dial design.
Firstly I see the ellipse case shape within the dial design which I find attractive.
Also, a light grey strap may tone down the look a bit and still work well with the case and dial.
That being said, it is quite a killer with the orange strap, not the usual Patek strap color,
but I couldn’t imagine it working better with any other dial.
Looking forward to hearing of your decision.
