+====== Seiko 9S85 ======

+The **9S8x** (and similar **8L5x**) family of [[Hi-Beat]] watch movements is the flagship mechanical watch product of [[Seiko]].
+===== Overview =====
+The **9S** family is intended to compete with limited-production Swiss movements from companies like [[Rolex]]. The 9S family are carefully finished with Tokyo Stripes and rhodium plating and are adjusted to six positions and are only used in Grand Seiko watches.
+The 9S8x family includes many notable Seiko movements
+  * [[2008]] "Super Hi-Beat" 8L88 featuring a 12 Hz (43,200 vph) design
+  * [[2009]] resurrection of [[Hi-Beat]] 10 Hz (36,000 vph) 9S85, following a tradition begun with the "Hi-Beat" automatic [[Grand Seiko 61GS]], manual [[Grand Seiko 45GS]], and ladies' [[Grand Seiko 19GS]] from the 1960's
+  * [[2018]] 8L55, a lower-finishing version of the 9S85
+  * [[2018]] 9S85 [[V.F.A.]], a tuned version of Cal. 9S85 with a variance of just -1 to +3 seconds per day
+The Calibre 9S families are assembled at Seiko's [[Shizukuishi Watch Studio]] in Morioka, Iwate prefecture, Japan, along with other high-end Seiko movements.
+===== Hi-Beat (9S8x) =====
+Seiko embarked on creating a new generation of [[Hi-Beat]] movements once the new mechanical Grand Seiko was established. The first fruit of this project was a special and extremely rare 43,200 "Super Hi-Beat" watch, the Credor GBBX998. Priced at over US$600k, only a single example was ever produced in [[2008]]. The [[Grand Seiko SBGH|Hi-Beat Grand Seiko]] with the 9S85 movement went into full production the following year. In [[2014]], Seiko introduced a [[Grand Seiko SBGJ|Hi-Beat GMT Grand Seiko]] using the related 9S86 movement.
