What time is it? Watches and horology

Looks like that's a term that has a more specific meaning in the horologery world than it has on a dictionary

an architectural decoration formed by two intersecting wavy bands

Update: not really that limited though

I’d assumed that anyone taking a guilloche class would be deep down the rabbit hole of watches, but that was a flawed assumption.

Guilloche is an expansive art that touches many aspects of craft beyond watchmaking, and the other students were interested in craft techniques in general, and had experience in woodworking, jewellery making, photography, and other artistic skills
