As soon as I spotted this watch in a local shop I knew I had to buy it. I remember buying the first HP 35 scientific
calculator back in 1973 in New York for over $300!! At the time this watch was released it cost over $600.
There were 2 versions made, stainless steel and gold plated. Although a few sellers on the Internet who have one for sale ask close to $4000
for a gold plated one with box and papers, my belief is that the stainless steel is a better buy. The reason is that once the gold plating flakes off.
there is not much you can do about it. This watch measures 40.76 mm across and is just right for today’s taste for bigger watches. It is 15.2 mm thick.
Right now the watch will fit a 7 inch wrist but I was lucky to buy a used bracelet so I have a few links to elongate if necessary The bracelet can be taken off and the watch can be worn on the leather strap. The lugs are 22 mm. The clasp contains a small stylus which can be easily removed to operate the keys which are depressed below the surface. This watch can perform all kinds of calculations and to learn all it can do please check out this link:
Let me add that this watch was of the first run and American made as you can see on the case cover. Later ones had both American and foreign components.
