Here is a very uncommon 1970 massive-sized Omega Seamaster caliber 861 chronograph with rare original bronze dial having black, light-and-dark-blue reflective registers, baton markers and hands, raised Omega symbol at 12:00, along with orange chronograph seconds. The pristine stainless steel (uncommon) Omega case measures 40x48mm having hidden lugs, polished pushers, and original Omega logo crown. The caliber 861 manual winding (high-quality) Omega movement (as seen in the 1960s-1970s Omega Speedmaster) was just cleaned, overhauled, and is keeping accurate time with all functions working perfectly. The original dial has some minor age marks, but nothing detracting. It is quite uncommon to come across these huge (hooded-lug) cased Omegas. Add to that the interesting and original dial along with one of Omega’s best movements and you have a really collectible and hard-to-find watch!
