Ten years is a good stretch of time to live with a watch. It is certainly enough time to tell the keeper from the walk-away.
Even if none of my better watches has been with me that long. Ten years is the time that I bought my first "expensive" watch ago. (A Fortis! Expensive! LOL! But I still have it, wear it and like it.)
Your sincere affection for your Carree PCs is certainly no secret here and given your pictures I do fully understand you. These old Carrees are growing on me more and more too. Maybe one will cross my way one day and then I will see what it has to say to me 
Thank you so much 14.000 posts of hospitality, knowledge and warmth!,
