I’m not a Seiko guy, I don’t dislike the brand and I have looked around for a Seiko wristwatch that I can wear on a NATO strap. I would give one a try at the right price, it would have to be automatic, that is given. I would probably prefer either an alpine or field style if I could find one. I like tool watches but it does not necessarily have to be a diver, I would consider a dress watch.

I had a Seiko as my first decent wristwatch, it was a slimline gold quartz with a black dial but I lost it some time ago. I have plenty of dive watches, so I don’t need another one, I have a number of dress watches, so I don’t need another of this style either. That rules out the Prospex range of dive watches for me, although I do see what people like about them. The automatic movements at Seiko are considered well made and robust, the finish is not spectacular, even the models with a display caseback.
At a guess, I would probably look at the Presage range, that would be the most interesting style for me. Seiko does not have a great reputation for bracelets, so that would go immediately and replaced with a NATO strap. That would make this timepiece interesting insofar as the style is now more casual. For me, this would not be a daily wearer, just thrown on the wrist every now and again for a change. A solid movement, a decent case, I would prefer a sapphire crystal as opposed to a mineral crystal and the dodgy bracelet can be changed out.
