Nothing has to be written about the good quality of Seiko - Seiko 5 models run (since) Decades (s) without interference. The SNZH models are just for KULTUhR, the Classic Diver design looks with leather strap even higher quality. The success of this clock is probably connected with the rigid business culture of competitor SMH - it is sort of the anti Watch the "outrage" generation. The comparable clock from Switzerland is expensive by a factor of 5-20, while the Seiko Service is clearly in the lead. Comparable mass ETA Caliber the 24XX and 28XX need after 5-8 years a full overhaul, my old Seiko-5 run smoothly for 25 years. However, the 5 star I can not give my second hand has a wrong eingenietetes lining - the polished side is unfortunately below.
