Black metronome with white dial

I found a small black Seiko metronome this afternoon around 3:15pm outside the Usher Hall on Lothian Road, Edinburgh. It's about 10 cm tall, with a glossy plastic shell and a white dial that sticks a bit when you turn the wheel. On the bottom there's a faded sticker with the initials 'ZA' and a tiny red dot sticker marked 'M1'—super distinctive if you spot it among a busker's gear. It still ticks when nudged, clearly used recently by someone who practices here. I know it probably belongs to a local musician or student, and I’d be glad to return it to its owner—please get in touch if this sounds like yours.
