Omega Geneve 135.041

The Omega Genève reference 135.041 was introduced around 1968 and saw its primary production span through to approximately 1970 or 1971. This model is significant as it represents Omega’s strategy in the late 1960s to offer high-quality, in-house mechanical timepieces at a more accessible price point, particularly appealing to a younger demographic. The 135.041 is characterized by its stylish tonneau case, a popular design of the era, and is powered by the reliable manual-wind Omega Caliber 601. It embodies a balance of Omega’s watchmaking heritage and classic, clean aesthetics, making it a popular choice for vintage watch enthusiasts seeking an entry into the Omega brand.

Key Details And Variations

Variations:

• Dial Variations:
  • Colors: The most common dial color was Silver, often with a sunburst or satin finish. Gold/Champagne dials were typically paired with gold-plated cases, also featuring sunburst finishes. Less common was a Grey (slate grey) dial, and a rarer Blue “racing” ceramic appearance variant has also been noted.
  • Markers: Applied linear or baton indexes were standard, often described as “wide” and characteristically featuring black lacquer or onyx inlays for enhanced legibility.
  • Lume: Tritium lume was applied as small dots or pips at the outer edge of or above hour markers, and sometimes within the hands. Dials featuring Tritium are marked “T SWISS T” or “SWISS T”. The patina of this lume (often creamy or “custard”) is a point of interest for collectors.
  • Branding: Applied metal Omega logo (Ω) and “Omega” name in the upper half, with “Genève” typically in cursive script in the lower half.
• Case Material Variations:
  • Stainless Steel: The most prevalent version.
  • Gold-Plated Steel: Typically a 20-micron gold layer over a stainless steel base.
• Movement Variations: The Omega Genève 135.041 is exclusively powered by the Omega Caliber 601. No other movement variations are typically associated with this specific reference.

Correct Dial: Original dials emphasize clarity and understated elegance. Key features include:

• Applied metal Omega logo (Ω) and “Omega” name.
• “Genève” inscription, usually in cursive.
• Applied linear or baton hour markers, often with black lacquer/onyx inlays.
• For lumed versions, “T SWISS T” or “SWISS T” markings at 6 o’clock.
• Original sunburst or satin finishes in silver, gold/champagne, grey, or blue.
• The condition of the original dial finish and lume plots (including patina) is critical for collectors.

Correct Hands:

• Typically “pencil” or “pointed baton” style.
• Often featured black inserts or luminous panels (Tritium) to match the hour markers, enhancing legibility.
• Material (steel or gold-tone) would correspond with the case and dial markers.

Correct Case:

• Distinctive tonneau or barrel shape.
• Dimensions: 34mm-35mm diameter (excluding crown), approx. 40.5mm lug-to-lug, approx. 10-10.5mm thickness, and 18mm lug width.
• Finishing: Typically a brushed sunburst pattern on the top surfaces, with polished sides and beveled edges.
• Case Back: Screw-down, usually with Omega logo and reference number on the inside. Some examples might have special engravings.
• Material: Stainless steel or gold-plated steel.

Correct Crystal:

• Original crystals were made of acrylic (Plexiglass).
• A key indicator of originality is a tiny, embossed Omega logo (Ω) in the center of the crystal, visible under magnification.

Correct Crown:

• The winding crown should be an original Omega-signed crown.
• The style would be appropriate for a late 1960s manual-wind dress watch.

Additional Details

Movement (Omega Caliber 601): The Omega Caliber 601 is a manual-winding movement with a lever escapement, 17 jewels, and an operating frequency of 19,800 BPH. It offers a power reserve of approximately 48 hours and typically features Incabloc shock protection. The Caliber 601 was generally adjusted to two positions. Recognizable by its copper-colored finish, it’s an evolution of the Caliber 600, featuring an excenter regulator. Produced between 1962 and 1970, its manufacturing timeline aligns perfectly with that of the reference 135.041. The Caliber 601 is well-regarded for its robustness, reliability, and ease of servicing, representing Omega’s commitment to quality even in its more accessible lines.

Original Presentation (Straps & Bracelets): The Omega Genève 135.041 was commonly retailed on a leather strap, often complemented by an Omega-signed pin buckle. Evidence also points to the availability of original Omega metal bracelets, with one specific mention of an Omega Milanese mesh bracelet (with Ref. 2028 endlinks) being correct for this reference. The presence of an original, period-correct bracelet significantly enhances collector value.

Market Standing & Collector’s Perspective: The Omega Genève 135.041 is considered an accessible entry point into vintage Omega ownership, offering brand prestige, a reliable in-house movement, and classic late-1960s styling at a generally more attainable price than flagship models. Key value drivers include:

• Overall Condition: Unpolished cases with sharp lines, pristine original dials (especially “T” signed dials with attractive lume patina), and well-maintained movements are highly valued.
• Originality: Original crowns, crystals (with Omega logo), hands, and any accompanying original bracelets or buckles are significant.
• Dial Variations: While silver is common, rarer dial colors like blue or grey, in good condition, can command a premium. The watch is praised for its clean, simple design and the reliability of the Caliber 601. It represents a blend of traditional craftsmanship and the contemporary style of its era.
