I am very happy with my Seiko Solar SNE109 diver watch purchase.  After about 3 weeks of ownership, the time is only 3 seconds fast, making the accuracy to be less than +5 seconds/month.  Seiko quality is renowned and is no exception here.  I replaced the stock rubber band with a Super Engineer II metal bracelet which dramatically improved the look and feel of the watch.  Only gripe is that the watch crystal is made of Hardlex and not of sapphire.  I already scratched the crystal once (!), but this never happened to my watches with sapphire crystals.  I bought diamond paste (3 micron and 0.5 micron) to buff out the scratch using my finger and it worked very well.  Knowing that I won't have to open the case to replace the battery makes this watch just that more practical and maintenance free.  Highly recommended.
