The styling of the case carries an authentic vintage aura with its curved and rounded appearance. Unlike the Luminor models that sport a patented crown-protecting device, the Panerai Radiomir watches contain wire lugs, a unique design that connects the straps to the case. With hand-wound or automatic mechanical movements topped with an anti-reflective, scratch-resistant sapphire crystal, the Panerai Radiomir collection is available in various dial sizes ranging from 42mm to 48mm.
