Seiko 7C46-6009 "Ashtray", October 1985
Seiko 7C46-6009 “Ashtray” Dive Watch
This is a watch that I built from an extremely rare “Salesman’s sample” case. I detailed this build process in a three-part video series here:
Part One: https://youtu.be/bLclhtMqiXQ
Part Two: https://youtu.be/vyaZznw0Obc
Part Three: https://youtu.be/DJAYpGwLPHc
Part Four: https://youtu.be/pOFCw_cWXlw
Watch is essentially in NOS condition, including an NOS replacement 7C46 movement from Seiko. Caseback is marked “SAMPLE”. All seals are new. Battery is new. I serviced the NOS movement before installing, as well as hunting down rare parts such as the black day and date wheels (very difficult to find, and the NOS movement only came with white), and some other calendar parts that were not provided.
Watch will be shipped on a new Uncle Seiko GL831 reproduction strap.
