The font they used is also very interesting and different in that it is much more elongated and geometric than usual. The edge of the bezel is polished steel with 60 little square teeth for grips that are both purposeful and decorative. Given that divers are so often defined aesthetically by the style and size of the bezel, it is an important feature to be well detailed and in this instance I believe that Seiko did an excellent job. Often I find bezels to be tacky and over done, which might actually be what draws me to the heritage divers in the first place; their bezels are always minimal.
The face of SNZH is simple, easy to read and quite nice to look at. The face itself is a metallic blue “sunburst” that shines radially from the center out. There are 60 markers around the edge, which supplement the markings on the bezel. At every quarter hour, except 15 where there is a the day/date window, there is a large beveled metal insert with a slightly tapered shape and at every five minutes there is a smaller beveled metal insert. The three dimensionality and polished look of the inserts is very attractive and gives the face a surprising amount of adornment, as though these were small steel diamonds. There are also thin white lines marking the rest of the minutes. On the inner edge of all of the metal inserts is a small rectangle of lume that aligns with the tip of the hour hand.
When the lume is charged this ring of rectangles looks very cool. Unfortunately the lume is very weak, so you wont see it without manually charging it with a light source. This is probably the biggest draw back of the watch, to be honest. I love it when lume gives a face a second personality in the dark, and I believe this design would have done that, but in the end, at night you only see the hour and minute hands, which are large roman swords with lume filling. The seconds hand is a thin polished steel rectangle with a lume filled triangle about halfway from the center to the long edge. The large day date window is the same as it is on all Seiko 5s. Though I appreciate the added functionality and value of having a day/date, I find it to be a bit visually disruptive in this circumstance. Nitpicking aside, I love the face of this watch. I think Seiko took a unique approach to capturing a vintage aesthetic without coming too close to any existing or famous designs.
The crystal of the SNZH is a domed hardlex mineral that measures 28.9mm in diameter. The dome of the crystal, which is really a welcome addition to any watch, bevels down sharply before reaching the bezel edge. Though I have only examined photos, I believe the shape is very similar to that of the Fifty Fathoms. The back of the watch displays the 23-jewel 7S36B automatic movement, which though undecorated is still quite nice to look at. So far, I have noticed no accuracy issues with the movement, as is to be expected from a Seiko. Why the SNZH has a 23-jewel movement and the SNK803k2 has only a 19 is unknown, but visually they are very similar. I have not noticed the rotor noise, as I did with the SNK, on this model. Whether this is due to it being a different movement or the bulk of the watch, I do not know, though a suspect it is the bulk.
