Photo credit to A Blog to Watch, but how about the quintessential "Max Bill 4" that he used on a lot of his time pieces. Looks like an upside down chair:

Watch has been at a local watchsmith's for nearly a year now so I can't access it at present. COVID-19 has him shut down as he is elderly, has leukemia, and several other health conditions which make him a high risk if he becomes ill. I have other watches so not in a hurry, but I hope he's able to work on a backlog of jobs while he's not interrupted by customers.
Seller photos from back when I acquired the watch.
