Pulsar Tiffany & Co Euro 18k Calculator.

I believe this rare 18k calculator model was designed for the Tiffany & Co department store in 1975/76. Just like the other limited solid gold Pulsar calculators, this piece would of set you back a cool $3950.

This Tiffany model has a different bracelet construction, and texture finish on the bracelet. I have only ever seen two of these models in my many years of collecting.
