The Specs
Read on and explore all the details.
The open heart window sits at the nine o’clock position while the day and night register is below at the six. As mentioned, the entire collection has been known for its incredible depth and attention to detail, and none of that is lost with the open heart variation. With a little help from its slightly domed sapphire crystal, a side view of the dial will showcase all of its ornate articulations, including the depth and layering between the open heart window and the movement itself. Dimension-wise, the RA-AS01 Open Heart measures just 41.5mm wide and 13.8mm thick. It is powered by the new automatic/mechanical caliber F6L24, and fully viewable through the exhibition case back. Unlike the deployant claps seen on similar models, a strap and buckle was included to conform to its slimmed profile.
