The patina on its dial may make it irresistibly unique. There are watches that lose the tritium of the hands, or oxidize, or lose strength in a certain area. There are diver watches that walk with the rotating bezel marked, worn out at times, and that tells us who used it for so long. It is possible that these watches, due to the passage of time, have lost precision, they may delay or advance the time a few minutes a month, but what does that matter when you look at the watch, 90% of the time you do not see the time, you just watch the watch !
