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

Doxa Conquistador Synchron Automatic Ref. 34.064 Vintage Watch from 1974

This Doxa Conquistador Synchron Automatic Ref. 34.064 is a bold Swiss vintage watch from 1974, built around the confident design language of the 1970s. Instead of a traditional round dress case, this model uses a strong stainless steel tonneau case with an integrated bracelet, giving it the look of a true period sports dress watch. The combination of a heavily patinated dial, day-date display, orange seconds hand, and brushed steel construction makes this Conquistador visually distinctive and full of vintage personality.

Aged Dial with Strong 1970s Personality

The dial has aged into a warm grey, champagne, and smoky tone, with visible speckling and natural patina across the surface. This is one of the defining features of the watch. Rather than looking plain or overly restored, the dial has a textured vintage appearance that gives the piece a much more individual character.

The Doxa logo sits below 12 o’clock with the “by Synchron” text underneath, connecting the watch to Doxa’s Synchron-era production. In the lower half of the dial, the “conquistador” and “AUTOMATIC” markings are still visible, giving the watch a clear model identity while preserving the aged, atmospheric look of the dial.

Day-Date Window and Orange Seconds Hand

At 3 o’clock, the watch features a framed day-date display with a weekday and date window. This practical complication gives the watch a very typical 1970s automatic layout and makes it more functional than a simple time-only dress watch.

The most eye-catching detail is the orange central seconds hand. Against the aged dial and silver-tone case, this bright color adds a sporty accent and gives the watch a more energetic look. It is a small detail, but it completely changes the personality of the watch and makes the design feel more period-correct.

Tonneau Stainless Steel Case with Brushed Finish

The stainless steel case has a wide tonneau shape with a rounded-square front profile, a thick polished bezel, and brushed surfaces across the upper case. This case style is strongly associated with 1970s Swiss watch design and gives the watch far more wrist presence than a conventional dress model.

From the angled views, the case shows a solid profile with integrated end links and a raised crystal that sits above the dial. The brushed finishing on the case top contrasts with the polished edges, creating a more technical and architectural look. Light scratches and signs of use are visible, consistent with a genuine vintage steel watch that has been worn and preserved over time.

Integrated Stainless Steel Bracelet

The stainless steel bracelet is an important part of the overall design. It does not feel like a random replacement strap, but like a natural extension of the case. The broad links, brushed surfaces, and recessed center details give the watch a complete 1970s steel sports-watch appearance.

The clasp is signed with the Synchron-style emblem, which adds a nice visual detail and makes the bracelet feel connected to the watch’s identity. Together with the tonneau case, the bracelet gives this Doxa a much stronger presence than a standard leather-strap Conquistador.

Automatic Swiss Movement with Synchron Rotor

Inside the watch is a Swiss automatic movement signed “Synchron 58” on the rotor, with “Seventeen 17 Jewels” and “Swiss” also visible in the movement photo. The automatic movement adds everyday practicality while keeping the mechanical charm that collectors expect from a vintage Doxa.

The open movement photo also shows a traditional Swiss automatic layout with a decorated rotor and visible mechanical components, reinforcing the watch’s appeal as a genuine 1970s mechanical timepiece rather than a quartz-era lookalike.

Signed Case Back and Reference Details

The case back is signed with the Synchron emblem and includes the reference number 34.064. The engraving also includes “2000”, “Fond Acier”, “Waterproof”, and “Swiss”, adding useful collector details and supporting the identity of the watch as a Doxa Conquistador Synchron model.

A Distinctive Steel Doxa from the Synchron Era

This Doxa Conquistador Synchron Automatic Ref. 34.064 is ideal for someone looking for a vintage Doxa with stronger personality than a simple dress watch. Its aged dial, orange seconds hand, day-date display, tonneau steel case, integrated bracelet, signed case back, and automatic Synchron movement all make it a memorable example of 1970s Swiss watch design.

A great option for collectors searching for a Doxa Conquistador vintage watch, a 1974 Swiss automatic day-date watch, or a stainless steel 1970s sports dress watch with authentic patina and strong period character.
