Omega Bund strap - information desired

I have found no information on the mighty net on this NOS strap and wonder about its authenticity. I’m looking for any insight from those with knowledge far beyond mine and the internet. Alligator leather on top, very smooth, supple leather on inside, “Omega” stamped buckle on inside but no other markings. 9.5” long, 1.25” wide at max, 18mm at lugs. It came out of an estate of a watchmaker in VA where I purchased 3 watches that were in beautiful condition and evidently well serviced and cared for. This band was part of the deal.
