Hello- Any Heuer dress watch experts in the house? I purchased the below Triple Calendar Moonphase a few years ago, and am trying to gather some additional information on the model. It seems to be from the 1950s, and the dial appears to be shared with similar vintage triple calendar watches from Leonidas, but besides that I'm in the dark on specific model information, references numbers, and even how much it's worth today. It looks like someone tried to touch up the dial, especially around the calendar ring, but is otherwise in excellent condition. Any additional background information you could provide would be greatly appreciated. Cheers!
