Hebdomas Orator 8 Days Pocket Watch - Looking for help to identify age/history

I am so intrigued by this Hebdomas Orator 8 Days pocket watch which belonged to my dad. I found it among his personal things after he died and have no idea where or when he may have acquired it.

I have seen similar pocket watches but not the exact one. I love the oval shape of the clock with the exaggerated 9 and 3.

Any help with identifying the year or history would be greatly appreciated.
