Can anyone help me by identifying this watch. Stainless steel back. Purchased
new in 1974. Serial number 2083276 which apparently means it was made in 1972
and has a 412H calibre. There is also number 1813 on its documentation. What
model is it? It it valuable? Any more info would be
appreciated./media/ckeditor_images/e19ace42bacc1ac62bcb355899022137.jpg
