The 41mm stainless steel case houses the automatic Omega caliber 2500 with a 48-hour power reserve. The mechanism is sealed into the case by a screw-down back on which the series number of each Limited Series watch is engraved as well as an embossed 007 gun logo. Performance is further improved by a free-sprung balance that allows for more precise adjustments of the watch. This James Bond edition will be one of the first 007 watches to feature Omega's new Co-Axial Escapement: the proprietary Omega technology that considerably reduces friction in the heart of the watch mechanism and offers improved long-term reliability and accuracy. The watch can now only be found in used watch stores and is regularly on offer at eBay (only buy from trusted sellers). The Omega Seamaster 300M Chronometer 2226.80 James Bond Limited Series, featuring the classic gun barrel emblem and 007 logo on the second hand, is a special edition of the Seamaster 2220.80 watch worn by Daniel Craig in Casino Royale.
