I love your enthusiasm for these 'cheap' old watches, the Dila looks great, I love the patina and the blued hands. If/when you bin the strap, I'd definitely keep the clasp, looks like it may be brass and just looks really cool and antique to me. Crazy story with the crystal as well, funny how that works sometimes. Keep it up, greetings from Germany.
Yes be a shame to bin the strap as so original but is bit on the small side. I might put it back up for sale on eBay in the future as it is. Thanks for watching
