Does anyone know what "SB" on this bracelet stands for and/or have any information about the manufacturer?

Let`s see a picture of the whole bracelet😀

It's not mine, listed on auction.. the twin-fold ends seem pretty unique/interesting but unfortunately it's nickel chromed :/ interesting nonetheless for the wrist that can pull it off 😁
