1914 RFC pilot movement identification help please

Hi

I'm new to this forum and to be honest I might be in the wrong place
altogether! My hobby is restoring watches from the WW1 period, and this is a
watch that once belonged to a RFC pilot. Its hall marked for 1914 and has a
fine centre second movement marked Stauffer, I've not come across a Stauffer
movement like this before. The pin setting layout is distinctive and the only
reference I can find is to IWC but I'm struggling to be honest so if any one
can say either way that it is a movement that IWC used that would be great.
Whatever the outcome is it's a really top grade watch but I would like to put
a makers name to it.

Stauffer, based in La-Chaux-de-Fonds and London, was the biggest watch jobber
in London in the 1900s to 1930s. They imported numerous brands amongst them
IWC (branded Peerless) and their own movements, the latter unbranded, branded
Peerless, Peertone or later Atlas.

What you got is no IWC, but one of the movements produced by Stauffer
itselves.

Thank you for your speedy reply.

Have you seen this setting plate that holds the clutch arm in place. Like I
said I cant find a Stauffer with an identical setting plate. I've them on
Henry Moser watches and on IWC all beit on pocket watches.

I found this today and again its a pocket watch but the bridges do look very
similar even the centre second friction spring.
