The case is made of steel \/ Rose Gold and measures 39mm in diameter. The dial is silver, protected by a sapphire crystal. The steel \/ Rose Gold bracelet closes with a folding clasp.\u003c\/p\u003e\n\u003cp\u003eThe watch features central seconds and a date display. The dial is set with diamonds. The watch is Chronometer-certified and water resistant to 50 meters. It is powered by automatic calibre 8800 with a power reserve of 55 hours. The Constellation dates back to 1952 and features the observatory medallion on the case back — a reminder of the precision records Omega set at the observatories in Geneva and Kew. The distinctive claws on the case edge and the design based on the 1982 Manhattan concept define the line to this day. Calibre 8800 belongs to the Master Co-Axial generation. It operates with the Co-Axial escapement, which reduces frictional loss compared to the classic lever escapement. The free-sprung balance wheel carries a silicon hairspring that is insensitive to magnetic fields and temperature fluctuations. As a Master Chronometer, it has been tested by the Swiss metrology institute METAS and is resistant to magnetic fields of up to 15,000 gauss. The watch is delivered new, with its original box and original documents including warranty and papers.\u003c\/p\u003e","brand":"Omega","offers":[{"title":"Default Title","offer_id":57165552484730,"sku":"131.20.39.20.52.001","price":12050.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/6677\/7027\/files\/frontal_13120392052001_19.png?v=1793287824","url":"https:\/\/www.horando.de\/en\/products\/omega-constellation-co-axial-master-chronometer-131-20-39-20-52-001","provider":"HORANDO","version":"1.0","type":"link"}
