Rolex, Submariner Date, reference number 16613, serial number N-. Extra serialnumber engraved by hand by ‘Heetman’under one of the lugs #2366 605. This is a stainless steel/gold model with a blue dial and bezel. This watch was stolen with box and papers. Unusual is the fact that although the watch has an N-serial it was sold in 2003 by Rolex AD Heetman in Rotterdam.
