This is a vintage genuine Seiko new old stock lady's Gold Tone watch band. The band was stored in a special Seiko container with it's own slot along side other bands and was not on display and did not have a separate container (the watch band has never been used).The band is 10mm. The length is 6 3/8" (without the case of the watch, which obviously will add to the length). A beautifully designed band. Style B533yx.
