This refined yet sporty wristwatch features a striking silver dial with contrasting sub-dials and a fixed rose gold bezel with a 1\/10th-of-a-second scale, capturing the spirit of Zenith’s legendary high-frequency chronographs. At its heart beats the El Primero 3600 automatic calibre, one of the most advanced chronograph movements from the Swiss manufacture, offering a central chronograph hand that makes a full revolution every 10 seconds for precise 1\/10th-second time reading, and a robust 60-hour power reserve. The elegant 41 mm case crafted in stainless steel and 18 k rose gold sits comfortably on the wrist, combining polished and brushed surfaces for dynamic visual appeal. With 100 m water resistance and a seamlessly integrated steel and rose gold bracelet, this watch is equally suited for everyday sportiness and refined occasions. The watch is unworn in like-new condition, comes with box and papers, and includes warranty documents dated.\u003c\/p\u003e\n\u003cp\u003eTechnical Data:\u003cbr\u003eMovement:\u003cbr\u003e• Zenith El Primero 3600 automatic calibre with column-wheel chronograph\u003cbr\u003e• Central chronograph hand with 1\/10th-second indication\u003cbr\u003e• Approx. 60 hours power reserve\u003cbr\u003e• Hours, minutes, small seconds, date, chronograph functions\u003c\/p\u003e\n\u003cp\u003eCase:\u003cbr\u003e• Stainless steel and 18 k rose gold\u003cbr\u003e• Fixed 18 k rose gold bezel with 1\/10th scale\u003cbr\u003e• Sapphire crystal and transparent caseback\u003cbr\u003e• Water resistant to 100 m \/ 10 ATM\u003c\/p\u003e\n\u003cp\u003eDimensions:\u003cbr\u003e• Case diameter: 41 mm\u003cbr\u003e• Case thickness: approx. 13.6 mm\u003cbr\u003e• Lug width: 20 mm\u003c\/p\u003e\n\u003cp\u003eStrap:\u003cbr\u003e• Integrated stainless steel and 18 k rose gold bracelet\u003cbr\u003e• Folding clasp with safety clasp\u003c\/p\u003e","brand":"Zenith","offers":[{"title":"Unworn \/ 2026","offer_id":48051448971496,"sku":null,"price":17600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/0043\/2053\/files\/1_590beebc-2257-4363-8460-e17e7f020e05.jpg?v=1770718089","url":"https:\/\/www.affordableswisswatchesinc.com\/products\/unworn-zenith-chronomaster-sport-ref-51-3100-3600-69-m3100-box-papers","provider":"Affordable Swiss Watches Inc.","version":"1.0","type":"link"}
