Product Details
Sporty, dressy, casual, this Baume et Mercier Riviera is a multifaceted timepiece that will please many personalities. Equipped with a "swiss-made" automatic movement, the combination of its steel case, sandblasted titanium bezel and gilt ring brings boldness to this timepiece. The perfect choice for people looking for versatility.
The Riviera is back again in subtly grayish hues, with a variation on the “Swiss-made” 42 mm automatic Riviera with a steel case and a slate-grey dial on an interchangeable grey rubber strap. The sand-blasted titanium bezel, fastened to the case with four functional screws, brings this contemporary piece a stealthy, driven look. A distinctive look reinforced by a gold-plated PVD ring, which provides luminosity in a perfect juxtaposition of the matte hue of the bezel and strap.
