A vintage Omega ref. N6607 manual wind wristwatch in an 18K yellow gold square case with Florentine finish bezel, featuring a signed black dial with gold index hour markers, gold stick hands, a subsidiary seconds dial at 6 o'clock, and a black Speidel leather strap with gold-tone buckle. Case measures 28 x 28mm; total weight 31.77 grams.

The N6607 square case is finished with a Florentine-textured bezel — the hand-engraved crosshatch pattern applied to the gold frame that was a hallmark of mid-century Swiss dress watchmaking, producing a matte, light-diffusing texture that contrasts beautifully with the deep black lacquer dial within. The black dial with gold index markers and gold stick hands creates a high-contrast, thoroughly legible face that reads as both bold and refined, while the subsidiary seconds dial at 6 o'clock adds a classical complication that was standard practice in the finest manual wind watches of the era. The signed Speidel black leather strap and gold-tone buckle complete a period-correct presentation that wears as authentically today as it did when new.

The Omega caliber 302 is a hand-wound movement from the late 1950s and early 1960s, representative of Omega's commitment to precision mechanical timekeeping in slim dress watch form during what many consider the golden era of Swiss watchmaking. Omega during this period produced movements of exceptional quality and longevity — calibers that, properly maintained, continue to run accurately decades after their manufacture. The N6607 reference is a gentleman's dress watch in the truest sense: square gold case, pure black dial, gold indices, and a slim manual wind movement that required no battery and rewarded its wearer with the daily ritual of winding. Collectors of vintage Omega prize these square-case Florentine references for their architectural elegance, substantial solid gold construction, and the irreplaceable character of a mid-century Swiss watch that has survived intact to the present day.
