Sapphire, a rotating timing bezel and a rubber strap make this a compelling comparison with larger sports watches. The 38 mm case is the key distinction for someone who finds many dive-style designs oversized.
A water-resistance number is not a blanket guarantee for every activity. Follow the manufacturer’s guidance, keep the crown secured and check fit before using it around water.
