Best guess, based on frequency it appears in Google image search, is this bracelet as shown at https://item.rakuten.co.jp/berich0112/ht1654/
You are fighting an uphill battle for this bracelet.
The design pattern is
- buy a vintage Grand Seiko or King Seiko
- buy a mid-tier vintage Seiko with a compatible bracelet (e.g. GQ, LM, Silverwave)
- salvage the bracelet for your GS/KS
- dump the mid-tier Seiko on eBay
Best of luck!
