Desabilitar um FUNCTION em mobile

[kaiquemix 1]

Olá pessoal queria que essa minha função scroll fosse desabilitada para mobiles, ou seja só estará ativa se a largura da tela for 1200px pra cima.

 $(window).scroll(function () {


    // Movimento primeiro box vermelho

    if ($(this).scrollTop() >= $("#box_img1").offset().top - $("#marcador_menu").offset().top) {

       $("#box_img1").stop().animate({"margin-right":"70px", "opacity":"1"},600);

       $("#box_text1").stop().animate({"margin-left":"100px", "opacity":"1"},600);

    } else {

    }

    if ($(this).scrollTop() >= $("#box_img2").offset().top - $("#marcador_menu").offset().top) {

       $("#box_img2").stop().animate({"margin-left":"100px", "opacity":"1"},600);

       $("#box_text2").stop().animate({"margin-right":"-50px", "opacity":"1"},600);

    } else {

    }

    if ($(this).scrollTop() >= $("#box_img3").offset().top - $("#marcador_menu").offset().top) {

       $("#box_img3").stop().animate({"margin-right":"50px", "opacity":"1"},600);

       $("#box_text3").stop().animate({"margin-left":"100px", "opacity":"1"},600);

    } else {

    }

    if ($(this).scrollTop() >= $("#box_img4").offset().top - $("#marcador_menu").offset().top) {

       $("#box_img4").stop().animate({"margin-left":"100px", "opacity":"1"},600);

       $("#box_text4").stop().animate({"margin-right":"-50px", "opacity":"1"},600);

    } else {

    }

    if ($(this).scrollTop() >= $("#box_img5").offset().top - $("#marcador_menu").offset().top) {

       $("#box_img5").stop().animate({"margin-right":"50px", "opacity":"1"},600);

       $("#box_text5").stop().animate({"margin-left":"100px", "opacity":"1"},600);

    } else {

    }

    });
