Baume & Mercier Joia Silvery, Sans, Satine croise Dial 28mm Women M0A10850

Epitomizing modern Swiss jewelry horology, Art Deco textural geometry, and feminine luxury, the Baume & Mercier Joia 28mm M0A10850 represents an exquisite expression of the Maison's jewelry-making heritage. Sculpted in a 28.00 mm surgical-grade 316L stainless steel round case with a profile measuring 7.20 mm in thickness and an 11 mm lug width, this jewelry timepiece is defined by its fixed stepped bezel set with 40 handset brilliant-cut natural diamonds (Top Wesselton, VS quality) that frame the face with light reflection. The dial showcases a silvery finish with a distinctive criss-cross satin-brushed texture (satiné croisé) that scatters ambient light in a woven pattern. Appointed with polished black Roman numerals, slender rhodium-plated baton hands, and a fluted winding crown set with a diamond cabochon beneath a scratch-resistant sapphire crystal, it is powered by a Swiss Made Ronda Calibre 751 two-hand quartz movement offering an extended 5-year (60-month) battery autonomy. Mounted on an articulated stainless steel bracelet featuring an embossed flattened link pattern (mailles écrasées) with tool-free quick-release interchangeability and a triple-folding deployant clasp, it is pressure-tested for 50 metres (5 bar / 5 ATM) of water resistance and backed by Baume & Mercier’s official 2-year international manufacturer warranty.
