Vintage Hamilton Thor Asymmetric Watch Grade 770 22 Jewels 10K GF USA Wristwatch

Watch Overview

In the late 1950s and early 1960s, Hamilton adopted the "space age" theme in its watch designs, coinciding with the enthusiasm of the American space program. These watches, known as "Asymmetrical", often had names inspired by space, although not exclusively. While many asymmetric models were equipped with electric movements such as the 500, 500A or 505, some featured mechanical or automatic movements.

A prime example of a mechanical asymmetric model is the 1959 Thor, which was produced for just three years before being discontinued in 1961. The Thor II, introduced in 1963 and produced for two years, closely resembles the Thor I.

Offered here is a rare and elegant Hamilton Thor wristwatch, dated from the 1960s.

It is a manual-winding watch, powered by the original Hamilton Watch Co. mechanical movement caliber grade 770, featuring 22 jewels with small-second hand. This timepiece beats at a frequency of 18,000 vibrations per hour with an approximate 45-hour power reserve. Made in the U.S.A.

The champagne dial boats a beautiful patina that speaks to its age. It features applied gold-tone Arabic numerals and hour markers, and matching gold-tone hands. The sub-second is located at 6 o'clock.

Cased in a 30.6mm asymmetric case featuring a dramatically unique triangular design with elegantly curved sides, all in 10K gold filled. Original signed crown. It comes on a original Hamilton genuine leather two-piece strap. It is in good vintage condition consistent with age and use. It is ready to wear and enjoy.
