Frederique Constant Classics Heart Beat Automatic – 40 mm Green Dial | Black Leather Strap | FC-310MCK5B6

Elevate your collection with the Frederique Constant Classics Heart Beat Automatic – Ref. FC-310MCK5B6, a refined 40 mm Swiss automatic timepiece that combines elegant design cues with mechanical authenticity.

Design & Craftsmanship

This model presents a polished stainless steel 40 mm case paired with a black leather strap for classic, versatile wear. The standout green dial features a guilloché centre pattern, Roman numeral hour markers and the brand’s signature open-heart aperture at 12 o’clock — giving a glimpse into the mechanical movement beneath. The Swiss automatic calibre FC-310 powers the watch with reliable performance and classic finishing, set behind a sapphire crystal and transparent case-back for full visual appeal.
