ETA 2789, Men’s Automatic","description":"\u003cp\u003eVintage Dugena Tropica Automatic from 1976 is a Men’s mechanical watch powered by the ETA 2789 caliber, combining a black sunburst dial, framed day-date display, applied baton markers and an original integrated stainless steel bracelet. Offered for sale with distinctive 1970s character, it carries visible TROPICA AUTOMATIC, 25 JEWELS and INCABLOC signatures.\u003c\/p\u003e\n\u003ch2\u003eDugena Tropica ETA 2789 — strong 1970s wrist presence\u003c\/h2\u003e\n\u003cp\u003eThe 38 mm stainless steel case and 43 mm lug-to-lug measurement give this Tropica a confident presence while remaining compact by modern standards. Its broad tonneau-style body uses brushed upper surfaces and polished side facets, creating a clear architectural frame around the round dial opening. The original integrated bracelet extends that geometry directly into the wrist, giving the watch a cohesive, purposeful appearance associated with sporty Swiss-German design of the period.\u003c\/p\u003e\n\u003ch3\u003eBlack sunburst dial with luminous-style baton markers\u003c\/h3\u003e\n\u003cp\u003eThe dial has a dark black-to-charcoal sunburst finish that changes subtly as light moves across it. Applied rectangular hour markers use pale central inserts and sit against a fine printed minute track. The DUGENA signature and emblem occupy the upper half, while TROPICA AUTOMATIC, 25 JEWELS and INCABLOC are clearly printed below the center. Small luminous-style plots at several hour positions add another visible period detail without disturbing the restrained layout.\u003c\/p\u003e\n\u003ch3\u003eFramed day-date display and broad central hands\u003c\/h3\u003e\n\u003cp\u003eA large framed day-date aperture at 3 o’clock provides both weekday and numerical date information. The broad hour and minute hands carry pale inserts that coordinate with the markers, while a slim central seconds hand reaches toward the minute scale. This strong contrast makes the display easy to read and gives the calendar complication a prominent but well-integrated role on the dial.\u003c\/p\u003e\n\u003ch2\u003eBrushed stainless steel case and integrated bracelet construction\u003c\/h2\u003e\n\u003cp\u003eThe confirmed stainless steel case combines a brushed top surface with smoother polished facets around the perimeter. Its broad shoulders and short transitions into the bracelet make the watch feel more substantial than a conventional round 38 mm design. Normal age-related marks are visible on the exterior, but the brushed grain remains clear. The case and bracelet together create a unified silhouette rather than the separate watch-head-and-strap appearance of a traditional dress watch.\u003c\/p\u003e\n\u003ch3\u003eRidged crown and practical case-side detailing\u003c\/h3\u003e\n\u003cp\u003eA ridged crown sits at 3 o’clock and provides useful grip for time and calendar adjustment. Its scale suits the substantial case without becoming visually dominant. No crown signature is clearly visible in the supplied photographs, so no signed-crown claim is made. The overall exterior remains functional and restrained, with the brushed case planes doing most of the visual work.\u003c\/p\u003e\n\u003ch3\u003eOriginal multi-link Dugena stainless steel bracelet\u003c\/h3\u003e\n\u003cp\u003eThe original integrated stainless steel bracelet is one of the strongest features of this example. Broad outer links are combined with narrower articulated center elements, creating a flexible multi-link construction that visually continues the case design. Because the watch is confirmed as all original, the bracelet is presented as part of the original watch components. Its exact fitted wrist circumference is not supplied.\u003c\/p\u003e\n\u003ch2\u003eETA 2789 automatic movement with day-date functionality\u003c\/h2\u003e\n\u003cp\u003eThe confirmed ETA 2789 automatic caliber powers the watch and its day-date display. The supplied product information identifies the movement as operating at 21,600 vibrations per hour, while the dial visibly confirms 25 JEWELS and INCABLOC. The movement has been serviced and the watch is listed as fully operational.

Its broad steel case, integrated bracelet, high-contrast dial and practical day-date display separate it from slimmer formal watches of the same period. The dial is also marked T SWISS MADE T, reinforcing the Swiss production identity of the watch and its ETA movement.\u003c\/p\u003e\n\u003ch2\u003eServiced originality and collector relevance\u003c\/h2\u003e\n\u003cp\u003eThis 1976 Dugena is confirmed as serviced, fully operational and fitted with all original watch components, including the integrated stainless steel bracelet. The dial remains highly legible, with visible aging to the luminous-style inserts and light wear on the case and bracelet consistent with vintage use. No box or papers are included. A 12-month warranty accompanies the watch.
