Roberto used the term "Frackuhr" in discussion with me a little while back, when referring to the next pocket watch he is most probably going to add to his collection. It's not a term we see/hear often - so I thought I'd share this post made by Ralph at this post by Jarrod

[i]They took a small 17 lig H4 movement and placed it in a big (but flat) case. It seems and confirms: flatness was the main criteria for "Frackuhren". (Could be "tailcoat watch", I could not find the correct english word ).
It was a time, it was not allowed to wear a wrist watch with a tailcoat.
This type of watch was worn in the breast pocket and fixed with a chain at the lapel.
Pocket watches where in the 1930's thicker and would not fit in this pocket easily, so this watch type (Frackuhr) was created, mainly flat for the breast pocket to be worn with comfort.
