FC-310MC5B6), a Swiss automatic watch that lets you see its balance wheel beating right on the dial. That open aperture, the signature of the Heart Beat line, sits within a silver-tone brass dial richly decorated in classic guilloché style and marked with traditional Roman numerals, a pairing that feels both romantic and refined.\u003c\/p\u003e\n\n\u003cp\u003eThe 40mm round stainless steel case keeps a slim 10.5mm profile, and an anti-reflective sapphire crystal protects the dial while keeping reflections to a minimum. Inside, the FC-310 automatic caliber drives the hours, minutes and seconds and is wound by the natural motion of your wrist, so it never needs a battery. A black leather strap with a buckle gives the watch a dressy, polished finish, and 50-meter water resistance means a swim in still water won't slow you down. It is a watch for anyone who loves to see, and not just feel, the craftsmanship on their wrist.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeart Beat Aperture\u003c\/strong\u003e – an opening at the balance wheel's position that shows the movement's rhythm.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGuilloché Silver-Tone Dial\u003c\/strong\u003e – an elaborately decorated brass dial in classic style.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoman Numeral Hour Markers\u003c\/strong\u003e – traditional numerals for a timeless read.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFC-310 Swiss Automatic Movement\u003c\/strong\u003e – self-winding, driving hours, minutes and seconds.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlack Leather Strap\u003c\/strong\u003e – a dressy finish with a classic buckle.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e FC-310MC5B6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollection:\u003c\/strong\u003e Classics Heart Beat Automatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e FC-310\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMovement Technology:\u003c\/strong\u003e Automatic (self-winding mechanical; an oscillating weight winds the spring with the motion of the wrist, no battery required)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, Minutes, Seconds, Heart Beat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Shape:\u003c\/strong\u003e Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Color:\u003c\/strong\u003e Silver-Tone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Length:\u003c\/strong\u003e 40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Thickness:\u003c\/strong\u003e 10.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLug Width:\u003c\/strong\u003e 20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Anti-Reflective Sapphire Crystal (impact and shatter resistant; anti-reflective coating deflects light)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color:\u003c\/strong\u003e Silver-Tone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Material:\u003c\/strong\u003e Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Features:\u003c\/strong\u003e Open Aperture, Heartbeat; Roman Numerals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Details:\u003c\/strong\u003e Classic guilloché decoration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e WR50 \/ 5 Bar \/ 166 ft (still water swimming)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBand Type:\u003c\/strong\u003e Strap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBand Material:\u003c\/strong\u003e Leather\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBand Color:\u003c\/strong\u003e Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClasp Type:\u003c\/strong\u003e Buckle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry:\u003c\/strong\u003e Switzerland\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTimepiece History\u003c\/h3\u003e\n\u003cp\u003eFrederique Constant was founded in 1988 by Aletta and Peter Stas, an entrepreneurial couple who shared a passion for watchmaking. Headquartered in Geneva, Frederique Constant has long aimed to make high-end Swiss-made watches available at more accessible prices. In 2004, it joined the ranks of Swiss watchmakers that develop and produce their own in-house calibers, and today its Manufacture in Plan-les-Ouates, Geneva, designs, develops and assembles more than 30 in-house calibers, including tourbillon, perpetual calendar and flyback chronograph complications. Frederique Constant celebrated its 35th anniversary in 2023.\u003c\/p\u003e\n\u003cp\u003eThe Heart Beat story began in 1994, when Frederique Constant introduced its first Heart Beat model, and the design quickly became one of its signatures. The idea is as simple as it is striking: by opening the dial at the position of the balance wheel, the watch shows that it is mechanical and lets the wearer follow the rhythm, or heartbeat, of the movement. This reference, driven by the FC-310 automatic caliber, sits within the Classics collection.\u003c\/p\u003e","brand":"Frederique Constant","offers":[{"title":"Default Title","offer_id":50878835753008,"sku":"FC-310MC5B6","price":1995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/1764\/4336\/files\/Heart_Beat_Automatic_a44dd331-6be7-45ac-ae84-6f96d95ba365.png?v=1792793912","url":"https:\/\/elizaldejewelers.com\/products\/frederique-constant-classics-heart-beat-automatic-fc-310mc5b6","provider":"Elizalde Jewelers","version":"1.0","type":"link"}
