Sun and Moon Open Heart

The open heart window sits at the nine o’clock position while the sun and moon register is below at the six. The entire Sun and Moon collection has been known for its incredible depth and attention to detail, and none of that is lost with the Open Heart. With a little help from its slightly domed sapphire crystal, a side view of the dial will showcase all of its ornate articulations: from polishing around the open heart display to the individual pips above each hour marker. Dimension-wise, the Sun and Moon Open Heart measures just 42mm wide and 14mm wide. It is powered by the new automatic/mechanical caliber F6L24, and fully viewable through the exhibition case back. Each model is equipped with a matte leather strap with a matching deployant clasp.
