Certainly excellent 18k Submariner ref 1680/8 from 1978.  I dont think i have ever seen a dial like this and probably wont again.  Is it perfect ? certainly not but features the most enchanting colors spectrum in a Wabi-sabi style appearance.  Certainly vibrant and attractive to say the least.  The dial looks very different in every kind of light with shades of Jade, turquoise, azure and tiffany with navy speckles.  The hands are original and match perfectly.  The case was polished in the past however is well proportioned and has well defined bevels.  The bezel is sharp and the fat font medium blue insert ties it all together.  The bracelet appears to be original and has almost no stretch with all links plus diver extension.  The movement is running strong and keeping excellent time however the last service is unknown.  Comes as watch only.  A tropical gold submariner that makes a bold statement
