1977 HP-01 LED LCD calculator digital watch model 1A-007 "Chrome" Prototype



Click Images To Enlarge



Here we have a stainless steel high glossy HP-01 calculator watch proto-type from 1977 in
unparalleled cosmetic and working condition. Untouched since 37 years.
This is a prototype of the model 1A-007 which has never been released.
There isn't any serial number or date of manufacture on the case back.
Unworn and original HP-01 watches are very hard to find nowadays since most of them are worn down
and defect after almost 40 years.
Look at the close-up pictures!
They speak for themselves - nothing more to say!
The whole watch is like it was when built by the HP engineers 37 years ago.
The serious collector will highly appreciate what an extraordinary museum piece this is.
Without this is the showpiece of any HP-01 collection.
Own something that you cannot find anywhere else in the world.

General HP-01 description:
The whole watch looks very impressive.
The LED display shows hours, minutes and seconds as well as date and month by red glowing digits.
These digits are bright, clear and complete.
Also this beautiful 1970's gadget features some specialties like ALARM,
COUNTDOWN TIMER, STOP WATCH and of course the calculator.
Needless to point out that all of these features work perfectly including the beeper of course.
This watch is 100% operational, 100% original and 100% reliable.
I specialize in these watches and if you’ve any further questions with respect to this auction

Single links can easily be removed to adjust the bracelet length to fit your wrist.
