BTW, if you're interested in the technology behind the quartz movement, I described it a bit in this comment. The co-axial escapement gets a lot of press, but quartz can be pretty cool as well.
Aesthetically, the modern version is flashier than the original (applied indices, engraved wave pattern, etc.) Modern bracelet has micro-adjustments in the clasp but, like the watch itself, is noticeably heavier. Coaxial movement will require regular service (currently $750, I think, from Omega) while quartz will mostly do just fine with nothing more than periodic battery replacement (assuming you're not actually diving with it).
