This is an authentic Omega black alligator watch strap (part number 98000242) that originally came with an Omega De Ville 4833.51.31 watch and is in good used condition. Your watch strap is 19mm wide where it connects to your watch and is 16mm wide where it connects to your buckle. Your longer strap piece is 10.5cm long and your shorter strap piece is 10cm long.

I have given you photos of your watch strap from every angle. Please use them to add to this description.
