Doxa Conquistador Synchron, Ref. 34.064, Cal. Eta 2789, 1974

An orange seconds hand cuts across the smoky, heavily patinated dial of Doxa Conquistador Synchron Ref. 34.064 from 1974. This Swiss men's automatic watch combines a wide stainless steel tonneau case, framed day-date at 3 and an integrated steel bracelet. Brushed upper surfaces, a thick polished bezel and a Synchron-emblem clasp give the watch its substantial period sports-dress presentation.

Smoky patina, orange seconds and a framed calendar

The dial has warm grey, champagne and smoky tones, with visible speckling and natural patina across the surface. Its beige warmth remains part of that aged metallic appearance. The texture is a defining feature of this example rather than an even, freshly restored dial finish.

Doxa sits below 12 with by Synchron underneath. Conquistador and AUTOMATIC remain visible in the lower half, identifying the model among Synchron-era Doxa watches. The signatures sit within the dial's actual aged surface.

A framed day-date display at 3 provides both weekday and date information. It brings daily calendar usefulness to the automatic layout. The orange central seconds hand adds a separate sporting accent against the warm dial and silver-tone steel, giving the face a more energetic character.

Tonneau steel with contrasting finishes

The wide tonneau case has a rounded-square front, thick polished bezel and brushed upper surfaces. Polished edges contrast with the case top, while the solid side profile, integrated end links and raised crystal give the watch its architectural appearance. Exact dimensions and crystal material are unspecified.

The broad case gives more wrist presence than conventional round dress watches. Light scratches and signs of use remain on the steel. Its brushed and polished surfaces retain the bold construction associated with 1970s steel watches.

Integrated bracelet and Synchron-emblem clasp

The stainless steel bracelet forms a natural visual extension of the case. Broad links, brushed surfaces and recessed center details complete the steel sports-watch presentation. The clasp carries a Synchron-style emblem, connecting that visible component to the watch's identity.

Together, the bracelet and tonneau case give this Conquistador a stronger presence than a leather-strap version.

ETA 2789 and the marked Synchron back

ETA 2789 provides Swiss automatic mechanical timekeeping. The rotor is marked Synchron 58, Seventeen 17 Jewels and Swiss. Its decorated finish and visible mechanical components form part of the movement layout, with self-winding convenience accompanying the day-date display.

The back has the Synchron emblem and reference 34.064, together with 2000, Fond Acier, Waterproof and Swiss. These markings preserve the reference and Synchron-era identity. Waterproof is historical case wording, with no current pressure-test rating established.

This used Doxa is fully serviced and comes with a 12-month warranty. Its 1974 production year, smoky speckled dial, orange seconds hand and integrated steel construction identify the particular watch alongside its actual surface wear.
