The first one is not by IWC.

The second one, with the 726xx case number and the 673366 movement number, is by IWC. It's movement (calibre) is a calibre 74 "finger bridge" movement made in 1917, and apparently sold in 1918.

The first movement was, I thought for a moment an IWC cal 56/57, but looking thoroughly I saw that the main plate is different from any IWC and moreover it has been marked "UH".
UH stands for "Union Horlogère",a Swiss association the members of which wanted to produce quality pocket watches. Alpina was the best known representative of Union Horlogère.
