I like the prominent use of Mokume Gane. I also like the emphasis on hand craftsmanship as opposed to the use of modern machinery. With regards to the second (unnamed) piece, what I especially appreciate is the pursuit of a higher level of accuracy via watchmaking knowledge (i.e. - the modified hair spring) as opposed to trying to achieve such through the use of modern machinery and/or computer-aided tools. I also like that in doing so Masahiro Kikuno - a young watchmaker - is paying homage of sorts to a part of Seiko's heritage.
