The Seiko-clock interested me, because I find the technology interesting. The problems described in part with the handling I can not understand, the accompanying description is more than adequate and comprehensible German. The clock is easy to read, the band makes a solid impression, only a sapphire glass would be desirable. As the clock will be used not for me as a diver's watch, the mineral crystal for my purposes, however, is perfectly adequate. Well made, nice styling (especially for the price !!) highly recommended.
