Omega's are some of my favourite watches..but having saved for one (and not yet buying...so close just haven't pulled the trigger yet) I have noticed their price spike in the last few years...likely coinciding with increased marketing. The sea master pro 300 is the watch that got me "into watches" but I now think there are a lot cooler watches for the money (nomos immediately comes to mind). Coming from an engineering mgmt background like yourself...I think it is fair to say that I'd rather pay for iconic industrial design, high quality materials and precision machining/movements than a brand image that is "cool"
That being said the co-axial is neat.
If you haven't checked them out yet the Tudor pelagos titanium and the Rolex milgauss are my favourite diver and anti-magnetic presently. Not super in love with the flieger aesthetically...but a saw an iwc flieger once that did it for me.
