Baume & Mercier Joia Silvery, Stamped, Sunray Dial 28mm Women M0A10847

Harmonizing Swiss haute joaillerie refinement with classical aesthetic purism, warm precious-metal accents, and slender wrist ergonomics, the Baume & Mercier Joia 28mm M0A10847 represents an elegant expression of contemporary feminine watchmaking. Sculpted in a petite 28.00 mm round case forged from surgical-grade 316L stainless steel, this luxury timepiece measures a slender 7.20 mm in profile with an 11 mm lug width. The mirror-polished stepped case is accented by a fluted cone winding crown set with a cabochon of natural black synthetic agate, providing an elegant jewelry touch. The dial showcases a radiant silvery stamped sunray finish that catches and reflects ambient light across dynamic radial arcs. Accented by warm 4N gold-plated Roman numerals, matching 4N gold-plated leaf-shaped (feuille) hands, and a minimalist two-hand display beneath a scratch-resistant anti-reflective sapphire crystal, it is powered by a Swiss Made Ronda Calibre 751 quartz movement offering an extended 5-year (60-month) battery autonomy. Mounted on a supple midnight blue calfskin leather strap featuring an integrated tool-free quick-release interchangeability system and secured by a polished stainless steel ardillon pin buckle, 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.
