Hi!! Finally I have got the best strap for my OMEGA Speedmaster Reverse Panda its the #Speedytuesday nato strap. The strap is a size 20 but I am able to get it in the OMEGA Speedmaster Reverse Panda 18 lug. See the pic However, the strap is very long other than that it was a perfect combination the color cut was perfect matching to the Dial. The strap was a really high quality way better than those china cheap nato strap much thicker and more comfortable. Fitting Picture
Its pretty easy than I expected at first. Moving for strap adjustment very easy. Very easy to get it on and off. But fitting on my wrist a bit too long for my wrist size.
