Ha fatto parte dei grandi produttori di orologi degli Stati Uniti, accanto a Hamilton, Bulova ed Elgin, e ha raggiunto il suo record di vendite nel 1953. Nel 1958 la società, diventata Gruen Industries, è stata venduta a pezzi.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #ddd; padding: 10px 0;\"\u003e\n\u003csummary style=\"cursor: pointer; font-weight: 600;\"\u003eDal Venus 188 al Valjoux 7730\u003c\/summary\u003e\n\u003cp\u003eQuando Valjoux assorbe Venus nel 1966, riprende il Venus 188, un cronografo a camma meno costoso da produrre rispetto alla ruota a colonne, e lo rilancia con il nome di 7730. È un movimento a carica manuale, con 17 rubini, che batte a 18.000 alternanze all'ora. Da esso discende il Valjoux 7750, uno dei cronografi automatici più diffusi.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails style=\"border-bottom: 1px solid #ddd; padding: 10px 0;\"\u003e\n\u003csummary style=\"cursor: pointer; font-weight: 600;\"\u003eA cosa servono la scala telemetrica e quella tachimetrica?\u003c\/summary\u003e\n\u003cp\u003eLa scala tachimetrica permette di calcolare una velocità media su una distanza nota. La scala telemetrica stima la distanza di un fenomeno di cui si vede la luce prima di sentirne il rumore, come un fulmine o uno sparo.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cstyle\u003e\n  \/* Description dépliée : suivre la hauteur des accordéons *\/\n  toggle-ellipsis.is-open:has(.fiche-faq) {\n    --height: auto !important;\n    height: auto !important;\n    max-height: none !important;\n    overflow: visible !important;\n  }\n\n  toggle-ellipsis.is-open:has(.fiche-faq)\n  \u003e .toggle-ellipsis__content {\n    height: auto !important;\n    max-height: none !important;\n    overflow: visible !important;\n    clip-path: none !important;\n    -webkit-mask-image: none !important;\n    mask-image: none !important;\n  }\n\n  \/* Retirer le dégradé uniquement en mode déplié *\/\n  toggle-ellipsis.is-open:has(.fiche-faq)\n  \u003e .toggle-ellipsis__content::before,\n  toggle-ellipsis.is-open:has(.fiche-faq)\n  \u003e .toggle-ellipsis__content::after {\n    content: none !important;\n    display: none !important;\n  }\n\n  \/* FAQ : une séparation fine, sans cadre *\/\n  .fiche-faq {\n    margin: 20px 0;\n    border: 0 !important;\n    color: inherit;\n  }\n\n  .fiche-faq \u003e details {\n    position: static !important;\n    margin: 0 !important;\n    padding: 0 !important;\n    border: 0 !important;\n    border-bottom: 1px solid !important;\n    border-bottom-color:\n      color-mix(in srgb, currentColor 18%, transparent) !important;\n    background: transparent !important;\n    box-shadow: none !important;\n    height: auto !important;\n    max-height: none !important;\n    overflow: visible !important;\n  }\n\n  .fiche-faq \u003e details::before,\n  .fiche-faq \u003e details::after {\n    content: none !important;\n    display: none !important;\n  }\n\n  \/* Question et indicateur d'ouverture *\/\n  .fiche-faq \u003e details \u003e summary {\n    display: flex !important;\n    align-items: center;\n    justify-content: space-between;\n    gap: 16px;\n    position: static !important;\n    margin: 0 !important;\n    padding: 12px 0 !important;\n    border: 0 !important;\n    background: transparent !important;\n    box-shadow: none !important;\n    list-style: none !important;\n    cursor: pointer;\n    font: inherit !important;\n    font-weight: 600 !important;\n    line-height: inherit !important;\n    color: inherit !important;\n  }\n\n  .fiche-faq \u003e details \u003e summary::-webkit-details-marker {\n    display: none !important;\n  }\n\n  .fiche-faq \u003e details \u003e summary::marker {\n    content: \"\" !important;\n  }\n\n  .fiche-faq \u003e details \u003e summary::before {\n    content: none !important;\n    display: none !important;\n  }\n\n  .fiche-faq \u003e details \u003e summary::after {\n    content: \"+\" !important;\n    display: block !important;\n    position: static !important;\n    flex: 0 0 20px;\n    width: 20px !important;\n    height: auto !important;\n    margin: 0 !important;\n    padding: 0 !important;\n    border: 0 !important;\n    background: none !important;\n    transform: none !important;\n    font-family: Arial, sans-serif !important;\n    font-size: 18px !important;\n    font-weight: 400 !important;\n    line-height: 1 !important;\n    text-align: center;\n    opacity: .65;\n  }\n\n  .fiche-faq \u003e details[open] \u003e summary::after {\n    content: \"−\" !important;\n  }\n\n  .fiche-faq \u003e details \u003e summary:focus-visible {\n    outline: 2px solid currentColor;\n    outline-offset: 3px;\n  }\n\n  \/* Réponses *\/\n  .fiche-faq \u003e details:not([open]) \u003e p {\n    display: none !important;\n  }\n\n  .fiche-faq \u003e details[open] \u003e p {\n    display: block !important;\n    position: static !important;\n    height: auto !important;\n    max-height: none !important;\n    overflow: visible !important;\n    visibility: visible !important;\n    opacity: 1 !important;\n    margin: 0 !important;\n    padding: 0 0 14px !important;\n    border: 0 !important;\n    background: transparent !important;\n    box-shadow: none !important;\n    font: inherit !important;\n    line-height: inherit !important;\n    color: inherit !important;\n  }\n\n  \/* Interligne du thème pour la description *\/\n  .fiche-description p {\n    line-height: inherit !important;\n  }\u003c\/style\u003e","brand":"Gruen","offers":[{"title":"Default Title","offer_id":53669306106203,"sku":null,"price":1700.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/7919\/9835\/files\/Gruen_Precision_Chronographe_770R_1970_s.jpg?v=1792063410","url":"https:\/\/vintagewatchspirit.com\/it\/products\/chronographe-gruen-precision-770r","provider":"Vintage Watch Spirit","version":"1.0","type":"link"}
