Great to see these asside. Really very close and I would also think they are related.
Still both companies had their own design protections.

Here is the Agassiz filing from 1910 which as No. 2 exactly shows the movement you have pictured.

And here is Gruen's 1911 filing for two similar movements, which I think are caliber 47 and 93. Still leaves caliber 89 open, but it is possible and has been usual practice to just protect one base deisgn and slightly vary it over different sizes, so that the cal. 93 protetion may have been also valid for cal. 89.

There are at least 10 other companies having very similar movements during the years around 1910. Some of them were clear copies of the LeCoultre design which have been the first with this style. Some were based on a famous copy from Sonceboz.
