Hamilton P2 LED James Bond watch







In 1957, The Hamilton Watch Co of Lancaster, Pennsylvania, produced the world's first electric watch. The Hamilton Electric Watch kept time with a traditional balance-wheel mechanism which had been used in timepieces for hundreds of years and was therefore no more accurate than any other watch. However, instead of the mainspring powering the mechanism, a battery was used to power the mechanism so the need to wind was eliminated. The Electric Watch was once the Favourite watch of Elvis Plesley,
After 13 years, the first digital electronic watch, a Pulsar LED prototype in 1972, was developed jointly by Hamilton Watch Company and Electro-Data, founded by George H. Thiess. John Bergey, the head of Hamilton's Pulsar division, said that he was inspired to make a digital timepiece by the futuristic digital clock that Hamilton themselves made for 1968 science fiction film “2001: A Space Odyssey” On April 4, 1972, the Pulsar was finally ready, made in 18-carat gold and sold for $2,100. It had a red light-emitting diode (LED) display. At That time only RED LED was available, and those tiny gold wire with Diameter of 1.0 mil (1/1000 of an Inch) was bonded manually wire by wire under microscope, imagine that there are 3 digits each consist of 7 segment , plus the two dot between hour and minutes LED, there were 23 wires to be bonded. That was a kind of Hi technology as they were very small and precise. As for the stainless steel version, it was sold about HKD$580 in 1973. It was very expensive there in Hong Kong.
Digital LED watches were very expensive and out of reach to the common consumer until 1975.  Texas Instruments started to mass produce LED watches inside a plastic case.
It was sold at HKD$250 in Hong Kong in 1977. I used to go to the Shop at Hung Hom near my college to see these new gadget stuff including Digital LED watch, at that time a  I earned HKD$18 a day in an Electronics Factory to repair Transistor Radio during Summer vacation.
Pulsar lose $6 million and the Pulsar brand sold to Seiko.

Today the Pulsar is still working perfectly, that is an important watch of the 20 Century
It contains a Magnet under the clasp, the magnet is sued to adjust the Hour and Minutes just by toughing the bottom of the watch, this design of setting the time was an innovation as it can have a better seal for dust and moisture to the PCB assembly or the watch.
