Serviced 1980 Seiko 150m Professional Quartz Diver.
7548-7000 is a highly regarded vintage dive watch, first introduced in the late 1970s. It holds a special place in Seiko's history as one of the earliest quartz-powered professional dive watches, serving as the predecessor to the now-iconic Seiko SKX series. It was designed to be a tough and reliable diver’s watch. It shares the same case design as the mechanical 6309-7040/7049, which is another legendary Seiko diver. The 7548 quartz movement was a high-quality, serviceable quartz caliber, which was unusual for the time. It was widely used by professional and recreational divers due to its accuracy and durability.
