I expect you did a google search of the case number and found your watch dial to be unique. Normally one would expect atleast one other example of your watch to come up somewhere but that does not seem to be the case. By changing the last didgets of the case back number and searching also came up blank. Just searching for omega cal 1481 also came up with nothing that looks like your watch, well there is one picture and it seems to be the same watch you have pictured but on ebay, however when I went to to the ebay page it does not show up there either. The possibilities, based on what we can find on the information superhighway with the information we are given,are:
1 the dial has been taken from another watch
2 the case back is not from this watch
3 the watch is a rare find, a one off prototype.
