The 7548 series of divers first appeared in the 1979 Volume 2 Catalog, along with two other ladies sized quartz divers as new models. And also the first time of Seiko to utilize this case design.
It came standard with a 150m rating, with a choice between two colors, black dial with black bezel insert and blue dial with blue/red bezel. It came standard only with the rubber strap GL831, where you can see this mentioned on the catalog shown below. The movement itself is serviceable, as a big portion of it is more or less the traditional mechanical watch design.
The 7548 is definitely my favorite diver of all time. Later on I will have a specific page made for the 7548, with all the info collected from the internet and links to them. Plus a good amount of photos that we could know more on this legendary piece that Seiko made, where after 40 years, people still love it and actively looking for it.
