Two of my favorite entry level Seikos. You've already ordered the mechanical, so I'm not sure if this advice will help you. I think it'll simply depend on whether he likes mechanical or quartz movements. If he gets excited about watches, he'll probably prefer the mechanical. If he is a novice, he'll probably prefer the (better looking) premier moon phase. Personally, I want both. I like my Ananta more than that SPB001, so I probably won't go back and buy one, but I still have room in my collection for the premier moon phase.
