Where can I buy a 'double tour' 12mm strap?

[jkh112]

I am having no luck finding a replacement strap for one of my wife's watches. It has a brown leather strap which goes twice around her wrist which from a few google searches seems to be called 'double tour'.
I have found a similar strap here:
http://www.watchbands.co.uk/Hirsch-Grace-Double-To...
but that is 14mm width and I need a 12mm one.
The watch is not an expensive one, so a few Hermes ones I have found are not in the right price range.
Does anyone have any suggestions as to where I might be able to find one?

Contact Hirsch, pretty sure they always offer a selection of widths for every style.

Will do, although they only list this style strap in 14mm and 18mm width on their website.
