Baume & Mercier Riviera M0A10620 Automatic 42 mm

This Riviera keeps to the collection's twelve-sided case shape, driven here by the calibre BM 11200 rather than the Baumatic movement found elsewhere in the line. Twenty-six jewels and a 38-hour power reserve sit inside a case over 40mm, with water resistance to 10 ATM and two years of international warranty.
