The Omega Seamaster 600 Ref. 135.011 is a quintessential example of 1960s Swiss watchmaking.

Omega Seamaster 600 - Silver Sunburst Dial

The dial is a beautiful silver sunburst, radiating light in subtle tonal shifts. Applied baton indices with black inserts provide excellent legibility, complemented by a printed minute track around the perimeter. The original “Omega” logo at 12 o’clock and “Seamaster 600” text at 6 o’clock remain crisp and well-defined, showing minimal aging.

Seamaster 600 135.011 - Hands

The hands are original baton style with black inserts, consistent with the hour markers for a coherent design. The central sweeping seconds hand extends elegantly toward the minute track, ensuring precision time reading and maintaining the understated elegance of the piece.

Omega Seamaster 600 135.011 - Slim Stainless Steel Case

The stainless steel case is polished and unpolished with sharp lug edges, retaining its factory proportions. At 34 mm diameter, it offers a perfect vintage dress watch size. The watch sits comfortably on the wrist thanks to its thin profile and balanced weight.

Seamaster 600 135.011 - Crown

The crown is the correct signed Omega crown, ensuring originality. Winding the watch is smooth and precise, a testament to the quality of the Caliber 601 movement inside.

Omega Seamaster 600 Leather Strap

This watch is fitted with a high-quality brown leather strap with an alligator-style grain, enhancing its dress appeal. While aftermarket, the strap is supple and perfectly matched to the vintage aesthetic of the watch.

Omega Caliber 601 Manual Winding Movement

Inside beats the Omega Caliber 601, a 17-jewel manual wind movement operating at 19,800 bph. This robust and accurate mechanism was widely used in mid-1960s Seamasters and remains a favorite among collectors for its simplicity and serviceability. As a fully serviced movement, it ensures reliable timekeeping for many years to come.

Heritage of the Omega Seamaster 600 in the 1960s
