A few years back on the now defunct dwf.cc, i raised the question about this watch. No one had ever seen one but Omega in the " vintage watches" section of their site did indeed list a Time Computer II in white goldfill, they even had a pic of one.The reference was "GF396031 on the base 196.0039- "GF" denoting "white goldfill 80 microns" (yellow goldfill is GD,ST stainless steel, solid 18ct yellow gold is BA). The new crappy all singing all dancing site doesnt list it. Looks like you may have a real rarity there
