Some research into what Patek "form" timepieces exist, such as hearts, pendant balls (Boule de Geneve), a scarab beetle and Farman backpack (so this does not include pieces such as dome/desk clocks, traditionally designed pocketwatches, etc.).
More historical contact needs to be added, but I wanted to share what I’ve completed to date:

If anyone has additional resources that discuss these type of pieces (if
you have seen forum posts, images, books, sites, instagram...if you own
one...), please let me know!
