L633.1, Men’s Automatic, 1976","description":"\u003cp\u003eLongines Octagon Ref. 4817-4 is a distinctive 1976 Swiss automatic built around an unusually geometric stainless-steel case and matching multi-sided dial architecture. Measuring approximately 33 mm across and 38 mm lug to lug, this all-original example is powered by Longines Cal. L633.1, has been fully serviced and is currently running at approximately +2 sec\/day. Its combination of sharply faceted steel surfaces, Roman numeral hour markers and compact automatic proportions gives it a very different presence from the conventional round Longines dress watches of the period.\u003c\/p\u003e\u003ch2\u003eGeometric Stainless-Steel Case and Octagonal Design\u003c\/h2\u003e\u003cp\u003eThe defining feature of Ref. 4817-4 is its strongly architectural case. Broad brushed stainless-steel surfaces form an angular outer profile, while the raised polished bezel follows the same multi-sided geometry around the crystal. Rather than treating the unusual shape as a decorative detail, Longines carried the design through the complete face of the watch, producing a coherent geometric composition from case edge to dial.\u003c\/p\u003e\u003cp\u003eAt 33 mm across and approximately 38 mm lug to lug, the watch remains compact by modern standards, but the broad case shoulders and large visual footprint make it appear considerably more substantial than the diameter suggests. The 20 mm strap width is particularly generous relative to the case size and further strengthens its proportions. A black leather strap currently fitted to the watch keeps attention on the angular steel case and silver dial.

Applied Roman numerals mark XII, III, VI and IX, while the Longines name and winged hourglass emblem occupy the upper half of the dial. The AUTOMATIC signature is positioned below the center, leaving the unusual architecture of the dial largely uncluttered.\u003c\/p\u003e\u003cp\u003eA framed date aperture is integrated into the lower-right portion of the dial, while slim hands and a central sweep seconds hand maintain the restrained 1970s aesthetic. The dial shows visible age-related spotting and surface patina, particularly when viewed closely under strong light. These marks are part of the actual vintage condition of this example and are visible in the photographs rather than concealed behind a generalized condition description. The applied numerals, signatures, minute track and date window nevertheless remain clearly defined.\u003c\/p\u003e\u003ch2\u003eLongines Cal. L633.1 Automatic Movement\u003c\/h2\u003e\u003cp\u003eInside is Longines Cal. L633.1, an automatic mechanical movement with central seconds and date indication. In this watch the movement has been completely serviced and is currently measuring approximately +2 seconds per day under our test conditions. That figure records its present observed performance rather than guaranteeing the same daily rate under every wearing condition, but it provides considerably more useful information about the current mechanical state than a simple statement that the watch is running.\u003c\/p\u003e\u003cp\u003eThe combination of automatic winding, date display and compact dimensions makes Ref. 4817-4 practical as well as visually unusual. Buyers comparing it with other \u003ca href=\"https:\/\/www.vintagewatchstudio.com\/collections\/automatic-vintage-watches\"\u003eserviced automatic vintage watches\u003c\/a\u003e can evaluate this example with a known calibre, documented current rate and completed mechanical service.\u003c\/p\u003e\u003ch2\u003eAll-Original 1976 Example with 12-Month Warranty\u003c\/h2\u003e\u003cp\u003eThis watch is represented as retaining all of its original watch components. The stainless-steel case preserves its strongly defined angular form, including the contrast between brushed outer surfaces and the polished multi-sided bezel. Normal vintage wear is visible, while the geometry that gives the reference its character remains clearly legible. The dial likewise retains its original layout with honest age-related patina rather than presenting as artificially flawless.\u003c\/p\u003e\u003cp\u003eFor a vintage watch of this type, the combination of originality, a fully serviced automatic movement and a measured +2 sec\/day current rate materially reduces the uncertainty that often accompanies an older mechanical watch. It is supplied with a 12-month movement warranty from Vintage Watch Studio.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eLongines\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eOctagon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReference\u003c\/th\u003e\n\u003ctd\u003e4817-4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduction Year\u003c\/th\u003e\n\u003ctd\u003e1976\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\u003eLongines L633.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMovement Type\u003c\/th\u003e\n\u003ctd\u003eAutomatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCase Material\u003c\/th\u003e\n\u003ctd\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDial Color\u003c\/th\u003e\n\u003ctd\u003eSilver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCase Diameter\u003c\/th\u003e\n\u003ctd\u003e33 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLug to Lug\u003c\/th\u003e\n\u003ctd\u003e38 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLug Width\u003c\/th\u003e\n\u003ctd\u003e20 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eSwiss Made\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy\u003c\/th\u003e\n\u003ctd\u003e+2 sec\/day\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\u003eFully Operational\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":"Longines","offers":[{"title":"Default Title","offer_id":50538444881985,"sku":null,"price":880.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/2768\/1857\/files\/longines-octagon-4817-4-l6331-mens-automatic-1976.webp?v=1790430847","url":"https:\/\/www.vintagewatchstudio.com\/products\/longines-octagon-ref-4817-4-cal-l6331-mens-automatic","provider":"Vintage Watch Studio","version":"1.0","type":"link"}
