The easy answer is obvious. My 1018 (see last picture) is the superior watch. But that $80 Seiko is an amazing value. If you want a very very very good mechanical watch that will do its job and never give you heartburn if something happens to it, this is the one to look at. I found it in a Wall Street Journal article "Penny-wise Advise on Mechanical Watches." They were all under $250 and at $80 the Seiko was cheapest...and looked the best IMO. I followed the links, read the specs and reviews, spent my $80 and a few days later Amazon delivered it. Its a decent size, 38mm, they had a 42mm version with manual and autowind, but I chose this for the size. To wind I have to shake it back and forth for a couple of minutes and then it will keep going as long as I wear it. But off the wrist, the power reserve is less than 24 hours in my experience. Setting the time, day and date is routine and easy, with the warning about not setting the day and date between 9 pm and 3 am. Accuracy has been very good...on par with my Rolex. The look of the Seiko is also excellent. The dial is well made, the case is a matt steel, and a little thick for my choice. The case back has the see through crystal and the movement is nice and shiny. And the movement is made in Malaysia. Not sure where the entire watch is assembled but so far it keeps working away and I have no complaints. The original nylon strap was very stiff and uncomfortable so I splurged another $20 and bought a softer Hadly Roma nylon and leather strap that is much more comfortable. So here are pictures...sorry you'll have to use the links until I get Imgur sorted out. It is a very decent field watch that will probably never be worth repairing...and yet if you love mechanical watches, how could you not make the effort.
As for the Rolex 1018...the 36 mm case is as perfect a size as ever made. The watch lays on my wrist and seems to float there. The folded metal Jubilee bracelet is perfect. It is my daily wearer...even more than my 1013. Hope this entertains all of you.
