Please help me find a signet ring lost in Regensburg

I'm David. I lost my late husband's signet ring on Friday, somewhere between the park and the bus stop. It's an old watch with a cracked leather strap. It isn't valuable to anyone else, but it's one of the last things I've of husband. I've retraced my steps twice and asked at the shops and the bus company. If you've found it, or you have a bin, a bench or a hedge you could check, I'd be grateful. A finder's thank-you is waiting. Please use the offer button here rather than sharing any numbers publicly. Thank you for sharing this and for keeping an eye out.
