Citizens' super-titanium models are manufactured from a light-weight material, more scratch-resistant than standard stainless steel. Each model is carefully crafted to ensure user comfort, whilst remaining anti-allergic and wearer friendly. The Promaster range offers a great alternative for the avid diver and adventurer. These sports watches feature a water-resistance level of up to 200m, combined with an air-tight screw-down crown to keep the mechanical movement safe and secure.
