Seen in profile the Titan Ultra Slim is virtually invisible. With an incredibly slim movement of 1.15 mm, the Titan Ultra Slim is the slimmest watch in the universe, a mere 3.6 mm. You will not find a slimmer one anywhere. This mere line of a watch, with its elemental one-piece case is made from non-allergic stainless steel, its sapphire crystal makes it scratch resistant, with a strap in pure leather. It is water resistant up to 30 meters. A feature that's hard to find in slim watches. So, how many other watches like this will you find in the world? Zero.
