A very nice Dynamic III, with the earlier tritium dial which now has lovely creamy lume.  Model reference 5200.50 or 166.0310.


Both the warranty card and the receipt show that this watch was sold new in 1998.  They Dynamic III model was launched in 1997.


The Dynamic III has little or nothing to do with the earlier models, in much the same way that a modern Seamaster looks nothing like the 1950’s versions.  Apparently Omega took inspiration from 1953 military issued watch, so the Dynamic III has train track minute markers set on a black dial and sword hands, but then the modern upgrades begin.  So you get sapphire crystal, a calendar function and an automatic movement.  That movement is Omega calibre 1108, which has the advantage of being based on an ETA 2892/A2 so parts, if they are needed, should be readily available.  It is nicely finished and the dust cover is still fitted to this example.  Later examples of this model use Luminova so their numerals will look whiter than these earlier tritium dials, and even some earlier examples will have the dial swapped by Omega for a Luminova one unless you specify not to change the dial.  The original bracelet, part number 1570/870, is quite long and our sister website, SpareLinks.com, may have extra links if required.  The bracelet has been cleaned in our ultrasonic bath.

This watch will be supplied with the original presentation box, which was designed to be a pen holder once you took the watch out!  It also has the outer card box, receipt, warranty card, instructions and our Certificate of Authenticity.  The warranty card has the serial number re written on it, but as we have the receipt for a Dynamic from the same jeweller as stamped on the warranty card everything belongs together.

This watch has been checked against the Watch Register and has not been reported as lost, stolen or implicated in fraud, and a copy of that certificate will also be included.
