This Omega De Ville Hour Vision timepiece is one luxurious watch with amazing detail and craftsmanship. This particular annual calander has the blue dial and white gold hands. The Co-Axial calibre 8601 can be seen with a transparent case-back AND the sapphire crystal used as part of the side casing. This is one unique timepiece and a beautiful tribute to Omega's watch-making and design. We are clearing this out of inventory as an authorized dealer. We just happened to have had this watch in our inventory for a little over 2 years therefore we are ready to move on by selling this at a clearance price point. This will still come with the manufacturer's warranty. Please let us know if you have any further questions.
