I have an excellent shape / condition Omega Centenary / Constellation 0.925 Silver box for sale. All I want for this is $500US in my pocket. You pay Paypal fees and shipping. Any questions, just let me know. For shipping I live in Victoria, British Columbia, Canada.
There are actually a couple of other versions as well. I believe the early ones come with no pattern at all. Just flat silver, like the inside of the lid on mine. I have also seen them with the pattern on top of the lid only, not on the sides. I think the pattern one's, like mine will age better because the silver does not tarnish as much with the pattern on it.
