Seiko "Ghost Bezel" Automatic Chronograph - 6139-6040 . A truly exceptional piece of horological history, this vintage Seiko reference 6139-6040 captures the bold, innovative spirit of 1970s chronograph design. It is powered by the legendary Seiko Caliber 6139—celebrated as one of the world's very first automatic chronograph movements introduced in 1969, featuring a sophisticated column-wheel and vertical clutch system. What sets this specific example apart is its incredibly desirable "Ghost Bezel." The tachymeter bezel has naturally faded over decades of careful wear, giving the watch a deeply authentic, much-sought-after vintage character that simply cannot be replicated. Paired with its striking grey dial, contrasting square sub-register, and practical Day-Date complication, this timepiece is a highly collectible mechanical marvel. .
