This is a rather uncommon OYSTER CENTREGRAPH having a black, original dial with original pencil style hands. and sweep seconds.  This watch is uncommon due to its smaller boy’s size gold filled TUDOR OYSTER case.  The OYSTER winding crown has been replaced at some time with a non-screw down winding crown. The movement is a TUDOR made (by ROLEX) which has been cleaned and is accurate. Any case wear in the gold fill is truly not visible with the naked eye-looks very clean. This is the first time we’ve found an original black dial CENTREGRAPH!
