Based on what I have seen, the value for the 16610, 16570 and the 14060M are all stable and have been for some time (since 2009). The 16610 is stable at about RM14,000, the 16570 is about RM13,100 while the 14060M is about RM12,700. However this prices reflect the overall quality of the watches which is about 95 to 99% with complete box and papers. Run of the mill prices is about 10 to 15 % lower, watch dependent, i.e. overall quality, boxes and papers and age. The value of the 16570 is seasonal on which dial colour is the flavour of the month, white or black.
