This is a very rare original Promethium dial Buren dirty dozen watch in great condition and benefiting from being fully serviced by John Senior .
The cases Buren used for these watches are all Chrome plated which is one factor in why so few have survived in good condition as you can see with this example not only has the original P dial remained intact but the case is in very good original condition as well
By far the rarest type of dirty dozen watch to capture I am delighted to offer this one fully serviced and ready to go
