"It looks like somebody modified the bezel insert and dial" 🙄
Yeah, that’s the best part of the description. 😁 This is so bad, I could actually imagine wearing it ironically on occasion. But certainly not for 150€. 😉
That 15 looks like it was cut from a magazine.
The crystal looks like the original was missing and they took a plastic one from another watch and heated it and pressed it in by hand.
Unless this was done to a watch salvaged from a plane crash in a POW camp there's no sane excuse.
PS
I read of an American officer in a Korean War POW camp watching a Chinese guard make a watch crystal from a broken light bulb. He carefully chipped the glass to the proper size and shape, grinding the edges smooth with a rock.
Something like that would deserve a place in a collection.
