Pity that dial was redone. Never saw such a thing. http://www.ebay.com/itm/Vintage-195...147300?hash=item283c869ee4:g:aK8AAOSwYSRZi1MsPurchases made through these links may earn this site a commission from the eBay Partner Network
Looks like a Tavannes 834/836 family. At 8.75''' the movement is only 19.7mm in diameter. Not really a functional item of jewellry, unless it's just for the boyfriend or husband to keep track of time by.
I thought these were typically worn upside down by nurses so they could see the time and still use their hands... but maybe they come in a lot of variations?
