Which dealer have you chosen? Maybe the more important part of your decision.
Not sure if Omega ever made that model with a quartz movement, if that makes any difference to you. It does not closely resemble the current automatic version, either (minute hand shape, date font, subdial issue at minimum.) The subdial issue may be due to it having a quartz movement; just guessin' here.
Bottom line is that if you like the watch, buy it and see how well you did with your selection. Happy hunting.
