Its funny, I don't automatically register the 1921 as 'time only' simply because of its rotated dial...but it is an iconic time only model. The new 1921 Excellence Platine is still in my mind. Even the original platinum 1921 would be a real pleasure to have in rotation. Look what you've done now
I initially experienced this strap on the second Omega Snoopy, and found out that Jean Rousseau makes them for Omega, and it turns out you can order cordura straps from their site, including any custom requests.
