It's just an old stretch Spiedel band. I thought it looked pretty good with this one. My guess is it belonged to a smoker but I've owned a couple of these that turned this color as well. Here's another one I own that used to be silver.
I picked this one up today. 149.00 62 SC Ser. 19349751 I can't get over the condition. Any thoughts on the originality of the bracelet. Not a scratch on it. Lume only lasts a few seconds before it fades though....I guess I should consider that validation that the dial is original.
Nothing wrong with the dial Probably just been relumed at some point Who cares? - it's a lovely watch Congratulations
