Excalibur RD01 is equipped with a mechanical hand-wound movement with two tourbillons working in opposite rotational directions. They are also equipped with a differential calculating the average of the two tourbillons in displaying the time.
The upper part of the dial displays the dragging and retrograde minutes, along with the jumping-hour hand. The sapphire crystal case-back subtly reveals the power reserve.
This model is available in pink gold, white gold or steel, with a choice of white, black or brown mother-of-pearl dial, and carries the Poinçon de Genève quality hallmark.
