Rare Grand Seiko Heritage Spring Drive

Japan-Only Double-Stamped Dial, Ice Blue

This one runs Caliber 9R65, Grand Seiko's first-ever automatic Spring Drive movement, in an ice blue dial that shifts tone with the light. Dated 2006 via the included warranty card, it's a genuine Japan-only release with a rare double-stamped "Seiko" over "Grand Seiko" dial signature from before the brand sold anywhere outside Japan.

Why it's interesting

• Genuine Japan-only release: warranty card dated 12/2006, four years before Grand Seiko was sold anywhere outside Japan (international distribution didn't start until 2010)

• Rare double-stamped dial reading "Seiko" above "Grand Seiko," a pre-independence signature specific to this era

• 9R65 debuted in 2004 as Grand Seiko's first automatic Spring Drive, extending power reserve from 48 to 72 hours over its manual predecessor

• Automatic winding via a refined "Magic Lever" system, originally developed in 1959

• Glide-motion seconds hand, no tick, driven by a magnetic brake firing 256 times a second
