Dugena Monza Automatic Ref.251, Cal. 3338, 1976

Square Monza case with rounded 1970s design

The case is one of the defining features of this Dugena Monza. It has a square shape with softly rounded corners, giving the watch a stronger visual identity than a standard round dress watch. The polished steel-toned surfaces, short lugs, raised crystal, and broad front profile create a balanced 1970s look that feels both elegant and sporty. From the side views, the case appears slim enough for regular wear while still carrying the geometric character that makes the Monza series recognizable.

Silver sunburst dial with applied markers

The dial has a silver sunburst finish that changes tone depending on the light, giving the watch a clean and refined appearance. Applied baton hour markers are placed around the dial, adding depth and structure without making the design feel crowded. The Dugena logo sits below 12 o’clock, while the automatic text and day-date layout give the lower and right side of the dial a practical, balanced composition. The outer minute track keeps the watch easy to read and adds a precise vintage detail.

Day-date display at 3 o’clock

A key practical feature of this watch is the day-date display at 3 o’clock. The dual calendar window gives the watch everyday usability and clearly separates it from simpler no-date Monza models. The framed aperture is integrated neatly into the dial and works well with the square case shape, adding function without disturbing the clean 1970s design. This makes the watch suitable for buyers looking for a vintage automatic watch that is both distinctive and practical.

Automatic Cal. 3338 movement

Inside the watch is Dugena Cal. 3338, an automatic movement associated with the ETA 2770 family. This caliber belongs to the mid-1970s generation of automatic day-date movements and fits the character of the watch very well. The movement photo shows the automatic rotor and traditional mechanical construction, giving buyers a useful view of the mechanism rather than relying only on the exterior presentation. Automatic winding, central seconds, and day-date functionality make this Monza a practical vintage mechanical watch for regular use.

Caseback and movement transparency

The caseback image provides useful identification and condition details, while the open movement photo confirms the automatic construction. The back shows normal marks from age and previous handling, consistent with a used vintage watch from the 1970s. These visible details help present the watch honestly and give collectors more confidence when assessing the piece.

Black leather strap and versatile wearability

This Dugena Monza is fitted with a black leather strap that suits the silver dial and steel-toned case. The dark strap keeps the overall look clean and easy to wear, while allowing the square case shape to remain the main visual feature. The watch can work as a vintage dress watch, a smart-casual daily piece, or a collectible 1970s automatic for buyers who prefer shaped cases and practical calendar functionality.

Why this Dugena Monza stands out

This Dugena Monza Automatic Ref. 251 stands out because of its square 1970s case, silver sunburst dial, applied markers, automatic Cal. 3338 movement, and useful day-date display. It offers more visual character than a standard round dress watch while remaining restrained enough for everyday wear. For collectors looking for a vintage Dugena automatic watch with strong period design and practical functionality, this Monza is a compelling example.
