The movement is running and repeating smoothly. The subsidiary dials for day and date show a small scratch on the dial. As the watch was sold to Vacheron, the Audemars archives lack records indicating whether Vacheron subsequently sold the watch to Gubelin. The case exhibits light scuffs throughout, with heavier scratches on the back and band, likely from case openings.

This watch reflects a classic midcentury aesthetic, merging it with the modern, clean design popularised in the 1960s. Its dial echoes the design of three reference 5516 perpetual calendar wristwatches delivered by Audemars Piguet to Vacheron Constantin in 1959, the year before this watch was sold. Like the 5516 models supplied to Vacheron Constantin, this watch bears the Audemars Piguet signature on the case, dial, and movement.
