Hamilton struck first in using an electrical power source rather than a coiled piece of spring steel. Hamilton began research on the electric watch in 1946. Development began under the code name Project X. The first watch appeared on the market eleven years later when Hamilton sent out a Press Release on January 3, 1957.The company pioneered the electro-mechanical and electronic watches that eventually evolved into the prevalent watch movements sold in the market now.
They noted that the Electric watch used an oscillating motor powered by a 1.5 volt hearing aid battery instead of a mainspring.
From 1957 to 1969, Hamilton produced two calibres that went to market: the 500 and 505. Even though the market favored the designs, Hamilton couldn’t produce and sell enough watches to make it a profitable line of business.
In the mid to late 1960’s, Hamilton attempted to address the Japanese market by forming a joint venture with Ricoh. The marketing effort failed. The company sold the Ricoh watches by repackaging them as Vantage brand. Hamilton placed a Standard Time Corp 130E caliber label on the Ricoh movement. The 130E looks similar to the Hamilton 505 and has many interchangeable parts.
Landeron 4750 made the first Swiss electric movement. It went into production when Hamilton released the 505. Landeron competed directly with Hamilton.
Hamilton succeeded three watch firms manufacturing timepieces in the same facilities in Lancaster, PA, including the Lancaster Watch Company. The precursor to the Hamilton Watch Co., the Lancaster, Pennsylvania based Keystone Standard Watch Co., was started by Abram Bitner in 1886 with the purchase of Lancaster Watch Company's factory.
