Most IWC replica watches will come with a transparent sapphire case back that allows you to see the mechanical movement powering the watch. These movements use several different finishing techniques which allows the movement to shine in ways that unfinished metals couldn’t.
Breitling replica watches are a different type of watch and although they offer fine craftsmanship, they don’t always have a transparent case back.On that note, there are also many Breitling watches that don’t use mechanically powered movement but rather, quartz movements which are battery-powered.
Best Fake Breitling watches tend to have a more heavy-duty build. While it’s never recommended to give a watch, mechanical or otherwise, a blunt force trauma or shock, it’s possible that these things will happen. In the event that it did happen, I’d be more comfortable wearing a Breitling and not the IWC which tends to be a more refined watch and less of a tool watch like most Breitling watches.
