This Calvert branded AS 1194 has gold colored rings around the jewels on the wheel bridge. Cap jewels are used on the fourth wheel and escape wheel. The balance is protected by an Incabloc shock system.

The hour and minute hands are vintage. They were stripped, cleaned, painted, and lumed. The second hand is also vintage and was not repainted.

The color of the hands closely matches the color of the dial in normal light. The hands glow with a green tint in the dark.

The letters "EON" on the balance cock is the US import code for Calvert.

Text found on the train bridge includes "SEVENTEEN 17 JEWELS" and "CALVERT WATCH CO." which is self explanatory.

The barrel bridge contains the text "UNADJUSTED" meaning that at production time the movement wasn't adjusted for temperature, isochronism, and multiple positions which is normally only done for expensive, high-end movements. Before shipping the movement would have gone through minimum adjusting to make sure that it ran within specifications. Visible on the barrel bridge in the picture below is the text "SWISS" which indicates the movement was produced in Switzerland.
