This Omega Seamaster 600 dates to 1964 and exemplifies the mid‑1960s shift toward slimmer, more refined wristwatches. Its stainless steel 35 mm case and period acrylic crystal preserve the understated proportions and executive styling of the era. At the heart sits the hand‑wound Omega 600, a 17‑jewel caliber noted for stable performance and straightforward serviceability. Presented on leather with a signed Omega buckle and a signed crown, this reference speaks to collectors who appreciate authentic mid‑century design and the tactile rewards of a manually wound movement.
