Pulsar P4 3408

Pulsar Time Computer P4 Model 3408 Vintage 1975 SS Mens Dress Watch....33mm

The World's First LED Digital Watch. The Hamilton/Pulsar was the first LED solid state digital watch. It is well documented in history through the US Patent office and the Smithsonian Institution. The Seiko Watch Co. purchased the Pulsar name and owns all legal rights to the name. Any mention of the Pulsar name in reference to watches in this listing is solely in respect to the old original Pulsar LED watches that were manufactured by Time Computer, Inc. before the name was sold. A few months after the initial launch a convenient Auto-Set feature was added that no longer required a magnet for setting. The new 402 modules can be tapped 3 times in a row to activate setting mode. I am a watch collector as well as a buyer and seller of new, pre-owned, antique, and vintage watches. I only sell genuine, authentic, watches in 'Very Good' to 'Pristine' condition.
