My input may or may not be useful for your purposes, but I’m chiming in just in case.
I use WFS to create faces just for my own GW7, not to sell, and I also found it difficult to find the elements I wanted for my faces.
What I ended up doing was googling good, straight-forward-facing, clear images of high-end watches, bringing them into Photoshop and removing the hands and background. I then save it as a 450x450 120px png file. WFS has a pre-made folder called Image under Resources > Sample. I keep my faces there.
Here’s one of the original images downloaded from google:

Here’s the Photoshopped png file, ready for WFS:

For the weekday and date windows, I removed the text and, where needed, painted the interiors of them in Photoshop. Then in WFS, used the Date functions (via Add Component > Text and using Tags), to fill them appropriately with dates/times.
For hands I searched for online companies that sell replacement hands for watches (and sometimes even for clocks). Their ad photos were often good enough to use. Here’s an example site:

I then brought those into Photoshop, extracted them from their backgrounds and made png files that I sized to 50x450 120px. These must placed in the png file with the part of the hand that goes in the center of the clock centered in the file and the hand pointing upward, like this:

WFS has a pre-made folder containing a few hands. These are under Resources > Sample > Watch Hand. I place hands I make in that same folder, making one for Hour and one for Minute and/or Second and using the same naming convention WFS used for their hands.
I’d be happy to share any of my WFS projects with you, but I’m guessing you’re looking for more masculine designs! I’m not a developer, so my ways of doing things in WFS may or may not be the best, but let me know if you’d like me to post a project or two here.
