Welcome Tom that's a fine herd you've collected. Looks like your strong pull is to the dress watches, as opposed to the divers and other tool watches. I "swing that way" a lot myself, although I am also into divers and vintage chronographs.
I have some nice vintage Seiko dress quartz watches too but the breadth of yours far exceeds my meager of that ilk.
I have 3 of the 7546- powered SilverWaves - such a great design, comfortable, screw-down crowns yet dressy all the same. A truly great Seiko offering.
Thanks HiBeat I'd like to get into Divers and Chronos but prices have gone a bit beyond my means at the moment - that being said I have finally managed to snag a 7a38 which is in its way to me from Germany The 7546 is a particular movement favourite of mine, it pops up in so many interesting references and is such a rugged bit of kit, I've only had one fail to come back to life so far
