The Da Vinci ref 3750 was first introduced by IWC in 1985 at the Basel watch fair, The particular watch I have on auction today has a low serial number of 150, it was manufactured in October 1985 and was one of the earliest to be produced in gold with a accompanied gold bracelet. For the collector or investor it also comes with all its original individually date stamped paper work. Prior to 2008 this watch belonged to a private European watch collector and has been preserved and maintained as you would expect by a passionate watch collector since 1985. Although the Da Vinci is still manufactured by IWC, ref type 3750 is no longer in production. With early first year editions particularly in 18ct gold now being the most sought after of them all. As well as being a rock solid future investment it is also a watch designed and built to last forever, with that in mind this would also make a good inheritance purchase to keep in the family for many generations to come.

The IWC C.  is a 30 mm diameter, H 8.8 mm, 39 jewelled, 28,800 vph. automatic movement with a power reserve of approximately 44 hours. The watch's water-resistance is rated at 30 meters. The 18ct gold case is 39 mm in diameter with a height of 14.3 mm,The crystal is domed plexiglass and the Ref. 3750 has a screwed-down crown and pressure shut case-back. The chronograph start/stop button is at 2 o'clock and the reset button is at 4 o'clock. The case lugs measure 20 mm across. The Da Vinci is supplied with a wax-sealed vial containing a replacement century slide for the twenty-third, twenty-fourth and twenty-fifth centuries. A visit to the watchmaker will be required in January 2200 so make a note of this in your diary to have the new century slide installed in the watch, then mark your calendar for 2499 for your next IWC check-up.   The dial layout is as follows: the moon phase indicator is at 12; small seconds at 9; date indicator at 3 consisting of two rings - the odd dates on the outer ring, even dates on the inner; the months indicator ring at 6; the day of the week indicator at 9 and century-decade-year indicator between 7 and 8. The chronograph has center-seconds hand with a 30-minute counter and 12-hour counter at 12 and 6 respectively. Footnote.In 1985, the International Watch Company introduced the automatic chronograph Da Vinci with perpetual calendar and moon phase indicator. Excepting a visit to the watchmaker in February 2100 due to the vagaries of the Gregorian calendar*, the Da Vinci Perpetual Calendar will measure the minutes, months, phases of the moon and years without interruption or adjustment until the year 2499. In Schaffhausen the Da Vinci was regarded as the watch event of the 1980s.a watch designed and built to run until the twenty fifth century and beyond without ever having to set or adjust the seconds, time, day or date and never manually wind it up if used daily.
