AL-730NS4AE6B), a proper mechanical chronograph built with the strength of a true sport watch. The navy blue dial carries Alpina's triangle pattern and applied silver indexes filled with white luminous material, framed by a white outer ring with a black chronograph seconds scale. Three silver subdials with black hands track 30 minutes at 3 o'clock, 12 hours at 6 o'clock and running seconds at 9 o'clock, while a silver chronograph seconds hand tipped with Alpina's red triangle and a date window between 4 and 5 o'clock complete the layout.\u003c\/p\u003e\n\n\u003cp\u003ePowering it all is the Swiss-made AL-730 automatic chronograph caliber, with a generous 62-hour power reserve you can admire through the engraved see-through case back. The 41mm three-part case is brushed and polished stainless steel under an anti-reflective sapphire crystal, finished with a brushed and polished steel bracelet and push-button folding clasp, and 100 meters of water resistance means this Swiss automatic chronograph is ready for swimming, showering and snorkeling.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwiss AL-730 Automatic Chronograph\u003c\/strong\u003e – Self-winding chronograph movement with a 62-hour power reserve.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNavy Triangle-Pattern Dial\u003c\/strong\u003e – Luminous applied indexes and a white outer ring with a black chronograph scale.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThree-Register Layout\u003c\/strong\u003e – 30-minute counter at 3, 12-hour counter at 6, running seconds at 9 and a date between 4 and 5.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEngraved See-Through Case Back\u003c\/strong\u003e – A clear view of the automatic chronograph movement.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100m Water Resistance\u003c\/strong\u003e – Suitable for swimming, showering and snorkeling.\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 AL-730NS4AE6B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollection:\u003c\/strong\u003e Alpiner Extreme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Alpina AL-730, Swiss automatic chronograph\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower Reserve:\u003c\/strong\u003e 62 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, seconds, chronograph, date\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChronograph Counters:\u003c\/strong\u003e 30 minutes at 3 o'clock, 12 hours at 6 o'clock, 60 seconds at 9 o'clock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDate:\u003c\/strong\u003e Between 4 and 5 o'clock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e Brushed and polished three-part case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e Stainless steel, silver-tone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Diameter:\u003c\/strong\u003e 41 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Length:\u003c\/strong\u003e 42.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Thickness:\u003c\/strong\u003e 11.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLug Width:\u003c\/strong\u003e 16 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Back:\u003c\/strong\u003e Engraved, see-through\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Anti-reflective sapphire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Navy blue brass dial with triangle pattern\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Ring:\u003c\/strong\u003e White with black chronograph seconds scale\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMarkers:\u003c\/strong\u003e Applied silver indexes with white luminous fill\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSubdials:\u003c\/strong\u003e Silver with black hands and graduations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHands:\u003c\/strong\u003e Silver hour and minute hands; silver chronograph seconds hand with red triangle tip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 100 m (10 bar), suitable for swimming, showering and snorkeling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBracelet:\u003c\/strong\u003e Brushed and polished stainless steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClasp:\u003c\/strong\u003e Folding clasp with push buttons\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Switzerland\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTimepiece History\u003c\/h3\u003e\n\u003cp\u003eAlpina's story began in 1883, when alpinist Gottlieb Hauser founded a watchmaking cooperative in Winterthur, Switzerland, with fellow mountaineers, aiming to build robust watches for harsh mountain terrain. In 1938, Alpina introduced the Alpina 4, marketed on four qualities: waterproof, shockproof, anti-magnetic and rustproof. After a period of near inactivity from the early 1980s, Alpina was revived in the early 2000s by Aletta and Peter Stas, the founders of Frederique Constant, and it joined the Citizen Group in 2016.\u003c\/p\u003e\n\u003cp\u003eThe original Alpina Extreme Automatic of 2005 introduced a cushion-shaped steel case and a bezel with triangular screws, a nod to Alpina's red triangle logo, itself derived from a stylized Matterhorn. In 2022, Alpina relaunched the Alpiner Extreme Automatic, a model it describes as a return to its mechanical heritage and outdoor identity.\u003c\/p\u003e\n\u003cp\u003eIn January 2024, Alpina introduced a chronograph version of the Alpiner Extreme, powered by the automatic AL-730 caliber with a 62-hour power reserve and offered with a navy blue or silver dial.\u003c\/p\u003e","brand":"Alpina","offers":[{"title":"Default Title","offer_id":50878794793008,"sku":"AL-730NS4AE6B","price":3395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/1764\/4336\/files\/Extreme_Chronograph_Automatic_28def3c2-5a21-4162-b678-bfeca58fb758.png?v=1792792276","url":"https:\/\/elizaldejewelers.com\/es\/products\/alpina-alpiner-extreme-chronograph-automatic-al-730ns4ae6b","provider":"Elizalde Jewelers","version":"1.0","type":"link"}
