The MKS replica watch factory started with the IWC mark series, and the factory name is also taken from the first letter of the two words mark. In the early period, MK factories made impregnated, classic three-handed simple and easy-to-sell formal watches. Because impervious bottom watches are visually flawless, they are the first manufacturer of formal watches. Like the IWC mark series, the Portofino series and the Omega Butterfly Flying series are classic three-handed best-selling models. In fact, the mks factory is an upgraded product of the mk factory because it has been effectively improved on the overall level of the product.
