Baume & Mercier Hampton Classic XL OpenHeart 30mm x 40mm 65647 (2010)

The Baume & Mercier Hampton Classic XL Open-Heart Ref. 65647 exemplifies the brand’s elegant blend of classic Art Deco design and contemporary watchmaking flair. Its polished rectangular stainless steel case measures approximately 30 mm in width (excluding the crown) and 42 mm from lug to lug, with a slim profile of about 10.5 mm for a refined wrist presence. The silvered vertical guilloché dial features polished baton indices, Arabic numerals, and an eye-catching open-heart aperture at 12 o’clock that offers a glimpse of the balance wheel underneath. A domed, scratch-resistant sapphire crystal with anti-reflective coating enhances clarity, while a transparent caseback continues the mechanical showcase. Powered by the automatic in-house Calibre BM11824 (based on ETA 2824-2), it delivers 42 hours of power reserve, regulated by an Etachron system. The watch is completed with a brand-new black alligator-pattern leather strap and a double-folding clasp bearing the brand’s logo, striking a balance between sophistication and wearability.
