Technos 10504 1975 — First impression of Gradient Dial Elegance in Stainless Steel Automatic Form

The 1975 Technos 10504 embodies the refined yet bold design ethos of mid-1970s Swiss watchmaking. Its 36.0 mm tonneau-shaped stainless steel case, paired with an integrated bracelet, delivers a sleek, continuous silhouette. At its heart beats the Swiss-made automatic ETA 2789 movement, renowned for reliable precision timekeeping. The gradient dial transitions from a rich purple center to a near-black periphery, creating a captivating play of light and depth. A vertically positioned day-date complication at 6 o’clock adds visual intrigue and distinguishes this model from conventional layouts. This men’s dress vintage watch captures the era’s fascination with integrated forms, geometric balance, and mechanical sophistication.

Technos 10504 – Gradient Purple-to-Black Dial with Luminous Markers

The dial’s multi-tone gradient finish is a defining feature, providing visual richness and a dynamic aesthetic. Applied rectangular hour markers are filled with luminous compound, framed in polished steel for clarity and contrast. The precise white minute track encircles the periphery, complementing the bold design without overwhelming the color shift. The silver Technos logo and “Automatic” designation beneath 12 o’clock harmonize with the metallic accents, while the vertically stacked day-date display at 6 o’clock offers an unconventional yet balanced presentation.

Technos 10504 1975 – Faceted Baton Hands with Luminous Inlays

The hour and minute hands are broad, flat, and sharply faceted, finished in polished steel with luminous inlays for enhanced legibility in low light. Their lengths are perfectly proportioned for the dial layout, with the minute hand extending to the printed track and the hour hand aligning neatly with the markers. A slender, polished central seconds hand sweeps across the dial, underscoring the precision and refinement expected from high-quality vintage Swiss watchmaking.

1975 Technos 10504 — Stainless Steel Tonneau Case

The tonneau-shaped stainless steel case reflects the bold geometric styling of the 1970s. Brushed surfaces on the upper planes convey a utilitarian elegance, while polished bevels along the case edges catch light dynamically. The 36.0 mm diameter ensures balanced wrist presence, with a 43.0 mm lug-to-lug span providing excellent comfort. A slightly domed crystal follows the bezel’s contour, adding vintage warmth. The crown at 3 o’clock is modestly proportioned and neatly integrated into the case line. The integrated bracelet flows directly from the case, its brushed wide central links and polished flanks reinforcing the cohesive design language of the period.

Heritage of the Technos 10504 in the Mid-1970s Swiss Watchmaking Era
