A keepsake lost in Dar es Salaam: any news would mean the world

I'm Ruth. I lost my late grandfather's prayer beads last weekend, somewhere between the church 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 grandfather. 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. Every share helps. Thank you.
