I have a Seiko five watch from 1990 that still works perfectly after a watch repair. This particular SNXG47K is more beautiful, equally clear in the dark with luminous hands and hour markers, and probably more accurate. Like my old five watch, it is water-resistant but only to a certain extent. However, we are talking about a mechanical watch with 21 jewels that winds itself with the movement of the hand. For the price (I bought it for €85 when I did the evaluation), there is no competition.
