Before the IWC Ingenieur there was this...
Hi everyone,
Here's an example of an early anti-magnetic pocket watch. The outer case is silver but the inner case is made of iron (I am not yet sure of what it is) making it a faraday cage. It was likely cheaper to produce than watches with for example a gold escapement and a palladium hairspring, or parts made of other non-magnetic materials.
It's not a very spectacular watch, but it's well made. Quite a bit different also compared to most L. Leroy & Cie offerings from this period.
The cuvette speaks of an 'ecran paramagnetique'. I have looked for a patent specific for this watch, but was unable to find it.
Have a nice weekend!
Regards,
Gijs

I was following this one but didn't bid. L. Leroy et Cie had a tradition of anti-magnetic watches, ending with marine chronometers built entireley of non-magnetic materials. I'd guess it has a soft iron inner case, but who knows... I'm increasingly surpri...
