after market WWII era bands and bracelets (maybe 1950s)

I'm sure you all have bought an old watch that came with an interesting old band. Feel free to share anything after market, but I will start with these two types that I actually enjoy wearing. The first I'll call the coiled wire band, and it came to me with an old Hamilton military watch from wwii. It was FILTHY, and I probably considered tossing it rather than trying to remove decades of DNA and dirt, but the sonic cleaner did a nice job. Those with hairy arms might find it problematic, but those of us who are more "evolved" should not have too mucu trouble. Maybe these were the earliest expansion bands? If you are an expert, please chime in.

The second type is more like a bangle or cuff bracelet. Getting a watch mated with one of them can be tricky, but I find them comfortable and super easy to put on and take off. The one I show here is made by Don Juan in Chicago, IL. I have a few of these, but the others are not marked. It came to me with an old wwii era watch, forget the maker. It fits a 16mm lug, which seems the standard from that era.

I did find this on ebay sold on its original card with some info. Corrogo plated? Life Timer may have been the maker? Best of all....NO EXCISE TAX.
