It's certainly a factor.
But i think only the Omega variant has the springbar inserts. I went genuine Omega for that reason plus it was easier than going another route for me at the time.
I also understand Omega has tightened up in that area as the Silver Snoopy strap is now deemed to be exclusive to that watch.
The strap used to be available through the Omega catalogue. But I don't know if it's still in there?
So it's hard to get one in these parts unless a serial number has been provided and or the watch has been sighted by the Boutique before they will place the order.
