re: re: 1210 balances by judoS on May 21,2006 12:34 PM problem solved . almost all 1210 calibre balances are 18000vph but mr rolex chucked an odd one in. MINE!! I check the new balance spring and it was correct at 18000vph but the watch still gained 10 seconds per minute. the key works was correct at 12-1 when counting the train it came apparent that Mr Rolex put an extra leaf on the escape pinion making mine 15425vph good old mr Rolex !!!Thanks Howard !!
