Product description

The SPB143J1 is a relatively small diving watch of only 40.5 mm. Due to this size and the sleek design, it is a versatile watch that can be worn in both a sporty and business environment. The steel case, strap and bezel have a hard coating that protects the watch against scratches. The scratch-resistant convex sapphire glass is provided with an anti-reflective coating on the inside, so that the dark gray sunray dial comes into its own. The automatic 6R35 movement has a power reserve of 70 hours.
