Omega's newest limited edition is certainly one of their most important. The watch was created to help support its work with Orbis International, a non-profit NGO that focuses on preventing blindness and eye disease in the communities that need it most. The limited-edition De Ville Tresor features a 40mm stainless steel case with a domed gradient blue dial that features polished hands and applied domed indexes in 18K white gold. Its most unique detail is the blue teddy bear that replaces the 8 on the date wheel, a reminder of the toys given to children that undergo eye surgery. Each watch is powered by Omega's manually-wound Calibre 8511, which features an 18K red gold balance bridge and a 60-hour power reserve.
