UMF 24, Men’s Diving Vintage Watch","description":"\u003cp\u003eAnker KR Diver from 1978 is a boldly styled German hand-wound sports watch with a 39 mm case, rotating black timing bezel and high-contrast black, white and red dial. This all-original watch is powered by a serviced Ruhla UMF 24-family movement, is currently running at approximately +9 sec\/day and is fitted with a black NATO-style fabric strap.\u003c\/p\u003e\u003ch2\u003eHigh-Contrast Diver Dial with Red and White Minute Markers\u003c\/h2\u003e\u003cp\u003eThe dial is the strongest visual feature of this Anker KR. A deep black center is surrounded by a broad white minute track, with paired red-and-black accents marking the hours and large stylized Arabic numerals at 12, 3, 6 and 9. Broad luminous blocks between the numerals continue the functional sports-watch layout, giving the dial excellent visual contrast even before the rotating bezel is considered.\u003c\/p\u003e\u003cp\u003eANKER and the small KR emblem are positioned below 12 o’clock, while the simple three-hand display keeps the center of the dial relatively open. Broad luminous-filled hour and minute hands are joined by a slender central seconds hand with a rectangular luminous section near its tip. The combination of stark white graphics, red accents and black background gives the watch a much more assertive appearance than the restrained dress watches commonly associated with inexpensive German mechanical production of the same era.\u003c\/p\u003e\u003ch2\u003e39 mm Diver-Style Case and Black Rotating Timing Bezel\u003c\/h2\u003e\u003cp\u003eAt approximately 39 mm across and 44 mm lug to lug, the watch has substantial proportions for a late-1970s hand-wound model. The broad case uses sharply defined, sweeping shoulders around the round dial opening, while brushed upper surfaces contrast with polished case sides. Its relatively short 44 mm length keeps the watch compact enough to sit securely on the wrist despite the broad overall profile.\u003c\/p\u003e\u003cp\u003eThe black rotating bezel carries a clear elapsed-time scale with a triangle at zero, prominent 10-minute numerals and fine intermediate markings. Together with the oversized crown and high-contrast dial, it gives the watch an unmistakable vintage diving-watch character. No specific original depth rating is confirmed for this example, so it is best understood as a period diver-style sports watch rather than being assigned an unsupported water-resistance specification. Present-day water resistance should not be assumed without pressure testing.

The family uses a traditional pin-lever escapement and operates at 18,000 vibrations per hour, reflecting the straightforward, durable construction for which mass-produced Ruhla movements became known. The exact UMF 24 sub-variant is not assigned here because several versions were produced with differing layouts and specifications.\u003c\/p\u003e\u003cp\u003eThe movement has been completely serviced and is currently running at approximately +9 seconds per day under present test conditions. That figure represents its current measured performance rather than a permanent accuracy guarantee. A 12-month movement warranty is included.

Surviving Anker KR watches are documented with Ruhla movements, making the combination of Anker branding and UMF mechanics historically consistent with that cross-border commercial relationship during the divided-Germany era.\u003c\/p\u003e\u003cp\u003eThis 1978 example retains its original watch components and combines that industrial background with unusually strong visual design: a broad sports case, black timing bezel, graphic red-and-white dial and compact hand-wound movement. The fitted black NATO-style strap is a modern wear component and complements the tool-watch character without being presented as original to the watch.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eAnker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eKR Diver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eGerman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGender\u003c\/th\u003e\n\u003ctd\u003eMen’s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCaliber\u003c\/th\u003e\n\u003ctd\u003eUMF 24 family\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduction Year\u003c\/th\u003e\n\u003ctd\u003e1978 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDial Color\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCase Diameter\u003c\/th\u003e\n\u003ctd\u003e39 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLug to Lug\u003c\/th\u003e\n\u003ctd\u003e44 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLug Width\u003c\/th\u003e\n\u003ctd\u003e18 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMovement Type\u003c\/th\u003e\n\u003ctd\u003eManual Wind\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy\u003c\/th\u003e\n\u003ctd\u003e+9 sec\/day\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStrap\u003c\/th\u003e\n\u003ctd\u003eBlack NATO-style fabric strap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFully Serviced\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOriginal Watch Components\u003c\/th\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e12-month movement warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Anker","offers":[{"title":"Default Title","offer_id":50538445537345,"sku":null,"price":280.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/2768\/1857\/files\/anker-kr-diver-umf24-mens-diving-vintage-watch.webp?v=1790442936","url":"https:\/\/www.vintagewatchstudio.com\/products\/anker-kr-diver-cal-umf-24-mens-diving-vintage-watch","provider":"Vintage Watch Studio","version":"1.0","type":"link"}
