GUB 75, Men’s Automatic Vintage Watch","description":"\u003cp\u003eVintage Glashutte Bison Automatic from 1972 is a Men’s East German mechanical watch powered by the GUB 75 caliber, with a silver dial, applied gold-tone markers, framed date display and visible 26 RUBIS signature. Offered for sale with distinctive Spezimatic character, its gold-plated square case and black leather strap create a strongly period-correct early-1970s profile.\u003c\/p\u003e\u003ch2\u003eGlashutte Bison 1972 — bold Spezimatic geometry on the wrist\u003c\/h2\u003e\u003cp\u003eThe 35 mm case and 42 mm lug-to-lug measurement give this Bison compact vintage dimensions, yet the broad square body creates noticeably more visual presence than a conventional round watch of similar diameter. Straight projecting lugs and a circular dial opening establish the angular architecture associated with the model. The warm gold-plated exterior contrasts with the pale dial, while the 20 mm strap width gives the watch a substantial stance that suits its robust early-1970s design.\u003c\/p\u003e\u003ch3\u003eSilver dial with Spezimatic and Bison signatures\u003c\/h3\u003e\u003cp\u003eThe silver dial has a lightly textured finish with visible age-related spotting and patina. Applied rectangular hour markers use warm metallic tones and dark central details, while a restrained minute track keeps the perimeter clean. The scripted Glashütte name appears above SPEZIMATIC in the upper half, and BISON with 26 RUBIS is printed above 6 o’clock. These markings give the watch a clear visual identity without overcrowding the dial.\u003c\/p\u003e\u003ch3\u003eFramed date aperture and gold-tone handset\u003c\/h3\u003e\u003cp\u003eA framed date window sits at 3 o’clock and provides the principal complication. The gold-tone hour and minute hands are broad enough for easy reading and coordinate with the applied markers, while a slender central seconds hand reaches toward the outer track. The uncomplicated three-hand-and-date arrangement keeps the dial practical despite the expressive case surrounding it.\u003c\/p\u003e\u003ch2\u003eGold-plated square case with textured surface character\u003c\/h2\u003e\u003cp\u003eThe confirmed gold-plated case is one of the defining features of this example. Its broad square outline has softly rounded corners, a circular bezel and straight lugs that extend from the case body. Fine scratches, surface wear and areas of aging are visible across the plating, particularly on the broad upper planes. Those signs of use are presented as part of the watch’s authentic vintage condition rather than hidden behind an over-restored appearance.\u003c\/p\u003e\u003ch3\u003eLarge ridged crown for everyday adjustment\u003c\/h3\u003e\u003cp\u003eA prominent ridged crown sits at 3 o’clock and provides practical grip for time and date setting. Its warm tone matches the case and dial furniture, while its generous size works naturally with the substantial case architecture. No crown signature is clearly visible in the supplied photograph, so the listing makes no signed-crown claim.\u003c\/p\u003e\u003ch3\u003eBlack leather strap and 20 mm proportions\u003c\/h3\u003e\u003cp\u003eThe watch is fitted with a black crocodile-embossed leather strap between the 20 mm lugs. Its dark surface provides a strong contrast to the warm case and pale dial, helping the watch retain a dress-oriented finish despite the rugged square geometry. The strap is adjustable for practical wear; because the supplied data does not identify it as an original period strap, no originality claim is made for the strap itself.\u003c\/p\u003e\u003ch2\u003eGUB 75 automatic caliber with 26-jewel specification\u003c\/h2\u003e\u003cp\u003eThe confirmed GUB 75 caliber provides automatic winding and powers the central time display and date complication. The supplied product information identifies the movement as using 26 jewels and a bi-directional rotor system, while the dial independently confirms 26 RUBIS. The movement is also marked with the code 721, supplied as evidence for the 1972 production year. The watch is listed as serviced and fully operational.

Its broad case, Spezimatic designation, in-house GUB 75 movement and 26-jewel specification give this example a clearly defined place within early-1970s German watchmaking.

The dial shows visible age-related spotting and the gold-plated case carries scratches and wear consistent with use over several decades. The black leather strap provides an adjustable contemporary fit without being represented as an original period component. No box or papers are included, and the watch is supplied with a 12-month warranty.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGlashutte\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eBison\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eGood Vintage Condition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGender\u003c\/td\u003e\n\u003ctd\u003eMen’s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCaliber\u003c\/td\u003e\n\u003ctd\u003eGUB 75\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCategory\u003c\/td\u003e\n\u003ctd\u003eAutomatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduction Year\u003c\/td\u003e\n\u003ctd\u003e1972 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Color\u003c\/td\u003e\n\u003ctd\u003eSilver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Diameter\u003c\/td\u003e\n\u003ctd\u003e35 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLug to Lug\u003c\/td\u003e\n\u003ctd\u003e42 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLug Width\u003c\/td\u003e\n\u003ctd\u003e20 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWrist Size\u003c\/td\u003e\n\u003ctd\u003eAdjustable strap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Material\u003c\/td\u003e\n\u003ctd\u003eGold Plated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMovement Type\u003c\/td\u003e\n\u003ctd\u003eAutomatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBox\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePapers\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFully Serviced\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFully Operational\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOriginal Watch Components\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e12 Months\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Glashutte","offers":[{"title":"Default Title","offer_id":44494213513281,"sku":null,"price":480.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/2768\/1857\/files\/glashutte-bison-cal-gub-75-mens-automatic-vintage-watch.webp?v=1788039202","url":"https:\/\/www.vintagewatchstudio.com\/products\/glashutte-bison-cal-gub-75-mens-automatic-vintage-watch","provider":"Vintage Watch Studio","version":"1.0","type":"link"}
