Vintage 1985 Seiko 7548-7010 Professional 200m Divers Watch Serviced Original

This Seiko 7548 divers watch from April 1985 is in very good condition for its age. It is a rare transitional Seiko diver, only produced for the Japanese Market in very small numbers for about a year in 1984-5. 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 premium NATO strap has been fitted with Fat Springbars. A new Seiko Watch Battery has just been fitted and seals replaced, but the watch was not pressure tested so it is not currently guaranteed to be water-resistant.
Please study the photos and video carefully as they show the condition of the watch in more detail.
