The Mostro by Sottomarino is named after the large monsters of the sea. Build with a massive 51mm case, 57mm with the crown, this is a definite eye catcher. The large markers are very luminous and easy to read both day and night. The case is made from marine grade solid stainless steel which protects it from corrosion in the water. The lightweight molded silicone strap offsets the added weight of the larger 51mm case and is very comfortable to wear and can easily fit a man with a larger wrist. The watch also features a Japanese Quartz movement, rotating dive bezel and a hardened mineral crystal. Each Sottomarino comes with a 3 Year manufacturer warranty, included with each watch.
