These two Perpetual Calendar quartz divers have been discontinued but I had the opportunity to see them in the fresh recently. They are similar to the SKX007 and 009 but a lot smaller. I would say that they are mid size divers similar to SKX013 and 015.
Here are the watches side-by-side.
Here’s a few shots of them next to the vintage 4205 so you can have a feel of the diameter.
