Hello all,

I've just finished a major update to the page on my site ref Helvetia's Shock and Water protected 'Sports' watches.

The update starts from the first shockproof Helvetias in the mid 1920s and their link with Depollier and includes sections on their patent 'floating' spring mounted movement and examples of their watches branded as 'Aero' and 'Aeroplane' in the UK, Huber 'Nautica' and 'Secura' in Germany and Abercrombie & Fitch in the US.

Have a look here: https://www.helvetiahistory.co.uk/1930s-sports-watches

Hope you find it interesting.

Thanks.

Carl
