Is this an IWC?

Watch from my grandmother. Wondering whether it is an IWC based on what I have read online. Would love to solve the mystery. 

Thanks 

Laura

That is a gorgeous vintage ladies watch all the same  

It’s so small & dainty I was nervous to open it. The inside still moves beautifully. Thanks for the help so far

Hi Laura,

Sorry the watch is not an IWC, the movement appears to be a Rotary Calibre 450 as depicted in La Classification Horlogere 1939

And a comparision

Stauffer, who owned the Peerless trademark were no longer the IWC distributors for the UK sometime before 1936 as shown in this cover of "Watch and Clock Maker" - September 1936

Note the Stauffer advertisment at the top and the Edwin Harrop/IWC advertisment further down to the left.

A very nice watch to keep in the family.

Hope this helps.

I wish we had more of these expert views as stated by Greg Steer!
