The new Seiko 4RXX movement has made its way into the market. They can be found in the Presage line, the Seiko 5 line as well as the Superior line. This time round, I will take a look at a Seiko Superior that is powered by the 4R37 movement.
This variant of the 4R movement is characterized by a 24 hour indicator hand located in a sub-dial at the 11 or 12 o’clock position depending on the location of the crown. This hand cannot be set independently. It can however tell you whether you are in AM or PM time when your are setting the time.
Like the other 4R variants, the movement comes with stop second mechanism as well as hand wind capability. The crown is between the 4 and 5 o’clock position and I find that the lug kind of obstruct my thumb when setting the time or even hand winding the watch.
The watch comes with a slide rule bezel which is the same one found on certain Seiko chronograph models. It can be used to do conversion of weight, distance, etc from one unit of measurement to another. The watch comes with a instruction manual for the slide rule bezel.
The crystal is slightly curved as you can see in the side profile shots.
The watch is water resistant to 100m and comes with a display back showing the 4R movement.
Here are two closeup shots of the 4R37 movement.
There are bracelet variants but this particular variant comes with a soft rubber strap.
Instruction manuals and warranty booklet:
