Its purpose was to certify the precision of their timepieces by observing the stars. It featured dedicated pavilions, aligned with absolute precision, including a meridian circle with a retractable roof. The observatory is still active today, affiliated with the CNRS (the French national research center) and committed to time-frequency metrology.\u003cbr\u003e\u003cbr\u003eThe meridian circle observes a single point in the sky: the line where, every night, stars cross the north-south axis of the observatory. From each transit, astronomers derived two simultaneous certainties: the exact time and the star's position. Besançon watchmakers went there for this direct reading of the sky, rather than relying on calculation, to regulate their watches.\u003cbr\u003e\u003cbr\u003eThe Spacegraf's \"celestial vault\" disk transfers this principle to the wrist. The meridian circle captured the sky as it passed in front of its fixed telescope; the disk, however, rotates continuously and is set exactly to the 23 hours, 56 minutes, and 4 seconds that the Earth takes to complete one full rotation on its axis relative to the stars. At every moment, it shows the portion of the sky actually visible above you: the same data that the Observatory once read among its stars, now in perpetual motion on a dial.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cp class=\"h1\"\u003e\u003cstrong\u003eYEMA WOODEN BOX AND 5-YEAR WARRANTY\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp class=\"h1\"\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eEach timepiece is delivered in an elegant wooden box accompanied by a personalized International Warranty card.\u003c\/span\u003e\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e","brand":"Yema Manifacture","offers":[{"title":"Default Title","offer_id":67628983484806,"sku":"60.26.32.06.TEL.L6","price":14500.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/8581\/6860\/files\/60.26.32.06.TEL.L6YemaSpacegrafHeureSideraleTourbillonVolantLimitedEditionGioielleriaRosaspinaBergamo.webp?v=1792074183","url":"https:\/\/gioielleriarosaspina.shop\/en\/products\/yema-spacegraf-heure-siderale-tourbillon-volant-limited-edition-60-26-32-06-tel-l6","provider":"Gioielleria Rosaspina","version":"1.0","type":"link"}
