The hour disc jumps 30\u0026amp;deg; on the hour to bring the next numeral into a wide aperture at six o'clock, while the minute disc sweeps once an hour around the cabochon against a Super-LumiNova ring marked in red. The enlarged numerals were drawn by typographer Simon Schmidt. Inside is a Swiss-made La Joux-Perret automatic fitted with Sartory-Billard's patented jumping hour module, with a 55-hour power reserve. The case alternates brushed and polished surfaces, stands 11.5mm thick and 44mm lug to lug, and carries 80 meters of water resistance on a Sartory-Billard rubber strap.\u003c\/span\u003e\u003c\/p\u003e","brand":"Sartory-Billard","offers":[{"title":"Default Title","offer_id":67736707334386,"sku":"U-029-039571","price":4241.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/7843\/5314\/files\/029-039571_0kZSDRIA4.jpg?v=1792023344","url":"https:\/\/kingjewelers.com\/products\/sartory-billard-sb10-jumping-hour-black-sapphire-39-5mm-watch","provider":"King Jewelers","version":"1.0","type":"link"}
