Vintage 1984 Seiko 7548-701A Professional 200m Divers Watch Serviced Original

This Seiko 7548 divers watch from September 1984 is in very good condition. It is a rare transitional Seiko diver, only produced for the Japanese Market in very small numbers in 1984. These were only produced in August and September 1984 according to the serial numbers, and all serial numbers are below 500, meaning a total of 1000 of these were ever made. This one being number 365 of September 1984.
 
The water resistance was increased to 200m by adding a screw down crystal ring like the later the Seiko Tunas. The watch features an English and Kanji day wheel.
The quickset day and date works perfectly. The bezel action is nice and crisp. The screw-down crown is silky smooth, and it keeps great time. It has just been fully serviced, including new Seiko Watch battery and all new seals. All original lume on hands and Dial. The watch does show normal signs of use and age but no abuse or bad knocks. Factory original finish on case (not re-polished).
A new Uncle Seiko Z199 Bracelet has been fitted with Fat Spring bars. A new Seiko Watch Battery has just been fitted and seals replaced. The watch was not pressure tested so it is not currently guaranteed to be water-resistant.
