Baume & Mercier Riviera M0A10716 Automatic 42 mm

A rotating bezel sets this Riviera apart from the rest of the collection, a genuinely functional addition rather than a decorative one, paired with water resistance to 30 ATM, well beyond anything else in the Baume & Mercier range. The calibre BM13-1975A drives it, 21 jewels and a 120-hour power reserve inside a 42mm dodecagonal case on a rubber strap. It suits travel and sport as readily as business, with an eight-year warranty extension.
