I love quartz divers. My two favorite quartz divers are the impossible to find 7546 and the just as hard to find 7548. I was able to pick up this nice find. A 7546 quartz diver Silverwave model with the Japanese day wheel. I like the 7546 and 7548 because they look just like their mechanical brothers in almost every way except the rotating dial is of a different design. It is slightly smaller and the insert was never available as a separate item. This makes restoration a bit of a problem as none of the dozens of rotating bezel inserts will fit either model. The dial is also different. I was lucky enough to win this one from Ramon in the Philippines and I can't wait for it to arrive.
