Which would you rather have – The Seikomatic R or the Business A. Same reference, so spot the differences! Model reference 8346-8000.
HOW DO WE DATE THIS WATCH?
From the serial number on the case back we can accurately date this watch to being made in September 1966. The retail price was ¥13,500, half the price of a Grand Seiko and roughly twice the price of a Seiko Skyliner. In the Japanese catalogue this is lists as a Seikomatic R, and the video shows this Business A next to the Seikomatic R with exactly the same reference number. We believe the Business R was intended for export markets.
CONDITION
With a 27 jewel automatic movement, that could also be hand wound (unlike the cheaper models), the Seikomatic and Business R models appeal to vintage collectors for their horological excellence and their everyday wearability. The date can be quick set, and the day wheel is in English (it is even in English in the Japanese catalogue picture.). This example has a few differences on the dial and the hands also have a line of black paint to make them more legible. The movement is a bit smoother to wind than in the other watch we have. The bracelet is quite long and our sister website, SpareLinks.com, may have extra links if required. The bracelet has been cleaned in our ultrasonic bath. The watch is signed on the dial, case, movement and clasp.
This watch will be supplied with our branded and reusable zipped travel case and cleaning cloth, and our Certificate of Authenticity.
