The hour markers and hands have developed patina. The lume on the dial has developed patina and aged to an attractive creamy color, some of the plots show signs of degradation. The hands have developed patina and the lume in the hands is a bit lighter than the lume on the dial which isn't uncommon. This watch has an 18k Jubilee bracelet with no. 54 end links, 19 links and hidden clasp; the bracelet is in overall good condition with some stretch between the links which is not uncommon for this style bracelet. The Rolex crown is still prominent on the clasp. The inside of the clasp is stamped "4 71" indicating it's from 1971. 

Pre-owned IWC Da Vinci Perpetual Calendar Chronograph ref. IW375803 (2006) was produced for only a few years during the 2000s and showcases IWC at its most technically ambitious. The watch is housed in a 41mm stainless steel case on a leather strap and features a perpetual calendar as well as a chronograph in a remarkably intuitive display. It has a fascinating dial layout. Every sub-dial performs double duty without ever feeling overwhelming. The register at 3 o'clock displays the date, while the sub-dial at 6 combines the chronograph's elapsed hours with the month, each indicated by its own hand. At 9 o'clock, the running seconds share space with the day of the week, again using separate hands for each display. The upper register houses a beautiful moonphase surrounded by the chronograph's elapsed-minute scale, while a discreet window at approximately 7:30 displays the four-digit year. Despite the sheer amount of information on display, the dial is still very balanced and surprisingly easy to read.
