Omega Rare Chronograph Ref 2287-1 Tropical Dial Men's Wristwatch C.1948 Including Box A highly attractive and historically significant gentleman's stainless steel chronograph wristwatch by Omega, reference CK 2287-1, dating from C.1948. This exceptional vintage timepiece houses the legendary Caliber 27 CHRO C12 (also known as the Caliber 321) column-wheel movement—the very same esteemed mechanism that powered the first generation of Speedmaster "moonwatches" to lunar exploration. The robust 35mm case presents beautifully proportioned lugs and round pushers, framing a wonderfully aged "tropical" black dial that has faded gracefully to a desirable grey-silver hue, complete with a tri-compax register layout and an outer tachymeter scale. This particular reference is a rare find in such charming condition, representing a cornerstone of Omega's post-war chronometry. Offered in working order. Size: 35mm x 42mm C.1948 Stainless Steel Private London Collector, cleared on registered loss database.
