FC-335MC4P5), a Swiss automatic watch that lets you see its heartbeat in real time. The 40mm round stainless steel case is finished in a rich gold tone that glows beautifully against a silver-toned brass dial, textured with a Clous de Paris guilloché pattern and set with traditional Roman numeral hour markers. At 12 o'clock, the signature Heart Beat opening reveals the escapement swinging back and forth, a living reminder that a true mechanical movement is at work on your wrist.\u003c\/p\u003e\n\n\u003cp\u003eThat movement is the Swiss-made FC-335 automatic, which winds itself from the natural motion of your arm, so there is never a battery to replace. Along with hours, minutes and seconds, it follows the phases of the moon and shows the date with a pointer, giving you a richly detailed dial that still reads cleanly at a glance. An anti-reflective sapphire crystal keeps everything crisp and protected, and a brown leather strap with a buckle closure completes a refined, traditional look that pairs as well with a tailored suit as with a weekend blazer.

The Heart Beat Moonphase Date carries that idea into the Classics collection, where the open aperture at 12 o'clock is paired with a Clous de Paris guilloché dial, Roman numerals, a moon phase and a pointer date in a sturdier, more contemporary case.\u003c\/p\u003e","brand":"Frederique Constant","offers":[{"title":"Default Title","offer_id":50878835261488,"sku":"FC-335MC4P5","price":3195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/1764\/4336\/files\/Heart_Beat_Moonphase_Date.png?v=1792793845"},{"product_id":"frederique-constant-classics-heart-beat-moonphase-date-fc-335mc4p6","title":"Frederique Constant Classics Heart Beat Moonphase Date - FC-335MC4P6","description":"\u003cp\u003eCrisp, classic and endlessly versatile, the Frederique Constant Classics Heart Beat Moonphase Date (ref.

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"},{"product_id":"frederique-constant-highlife-heart-beat-automatic-fc-310b4nh6b","title":"Frederique Constant Highlife Heart Beat Automatic - FC-310B4NH6B","description":"\u003cp\u003eThe Frederique Constant Highlife Heart Beat Automatic (ref. FC-310B4NH6B) proudly puts its mechanical soul on display, opening a window in the dial so you can watch the balance wheel of its Swiss automatic movement beating in real time. It is a modern, minimalist take on one of Frederique Constant's most recognizable designs, built here around a black brass dial decorated with the Highlife globe motif. The aperture sits right at the pole of that globe, a clever bit of placement that turns the movement's rhythm into part of the dial's artwork, while applied silver indexes and luminous hands and markers keep the time easy to read.\u003c\/p\u003e\n\n\u003cp\u003eThe 41mm stainless steel case measures 10.84mm thick and flows seamlessly into an integrated steel bracelet that closes with a fold-over clasp. For more casual days, an additional black rubber strap is included, giving the watch a sportier, more relaxed personality without losing any of its polish. The FC-310 self-winding caliber needs no battery, winding itself from the natural motion of your wrist, and anti-reflective sapphire crystal plus 100 meters of water resistance mean it is as comfortable at the pool as it is at dinner. For anyone who loves seeing the mechanics behind the time, this is a striking way to wear Swiss watchmaking every day.\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 pole of the dial's globe reveals the balance wheel in motion.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlack Globe Dial\u003c\/strong\u003e – black brass dial with the Highlife globe motif, applied silver indexes and luminous hands and markers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFC-310 Swiss Automatic\u003c\/strong\u003e – self-winding mechanical caliber powered by the motion of your wrist, with no battery needed.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntegrated Bracelet and Rubber Strap\u003c\/strong\u003e – stainless steel bracelet with fold-over clasp, plus an extra black rubber strap.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100m Water Resistance\u003c\/strong\u003e – suitable for swimming, showering and snorkeling, under anti-reflective sapphire crystal.\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-310B4NH6B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollection:\u003c\/strong\u003e Highlife\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e 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, wound by an oscillating weight; 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 41 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Thickness:\u003c\/strong\u003e 10.84 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLug Width:\u003c\/strong\u003e 25.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Anti-Reflective Sapphire Crystal (impact and shatter resistant)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color:\u003c\/strong\u003e Black\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 Indices, Luminous Hands, Luminous Markers, Open Aperture (Heart Beat), globe motif, applied silver indexes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e WR100 \/ 10 Bar \/ 333 ft (Swimming, Showering \u0026amp; Snorkeling)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBand Type:\u003c\/strong\u003e Bracelet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBand Material:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBand Color:\u003c\/strong\u003e Silver-Tone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBand Length:\u003c\/strong\u003e 254 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClasp Type:\u003c\/strong\u003e Fold Over Clasp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdditional Strap:\u003c\/strong\u003e Black rubber strap, included\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.

Two push-pins at the end of the bracelet allow tool-free changes between steel, leather and rubber straps.\u003c\/p\u003e","brand":"Frederique Constant","offers":[{"title":"Default Title","offer_id":50878836867120,"sku":"FC-310B4NH6B","price":2895.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/1764\/4336\/files\/Heart_Beat_Automatic_65cdd962-7197-45f9-87b1-38c9bb685374.png?v=1792793973"}],"url":"https:\/\/elizaldejewelers.com\/collections\/frederique-constant-heart-beat.oembed","provider":"Elizalde Jewelers","version":"1.0","type":"link"}
