Omega Swiss Manual-Winding Calibre 613 circa 1969

34.5mm polished stainless steel case with a 38-hour power reserve, dust-protected water resistance. Scratch-resistant hesalite crystal glass with a solid "Unishell" monocoque caseback, a minimalist thin polished fixed bezel, and a slender, low-profile round case architecture designed for ultimate mid-century dress distinction. Exceptional retro elegance and highly balanced on-wrist presence thanks to its radiant sunburst silver dial, crisp printed cross-hairs sub-tracking, and classic straight mid-century lines.

On a premium integrated heavy-duty stainless steel Milanese mesh sports bracelet featuring a secure adjustable sliding deployment safety clasp.

Minimalist late-1960s design era luxury tool watch model housing a legendary, high-performance Swiss hand-wound mechanical movement with a quick-set calendar function, featuring sharp applied baton indexes with blackened center facets, matching baton hands, a slender sweeping center seconds pointer, and a framed quick-set date window crisp at 3 o'clock.

Loose watch only, presentation box and original documentation absent. Immaculate vintage physical condition with zero dial spotting, sharp unpolished case contours, and excellent bracelet elasticity intact.
