While the subdials and the inner bezel of the “Grande Tapisserie” dial encompass the iconic blue hue of the original Royal Oak, a colour referred to as “Night Blue, Cloud 50” in the Manufacture’s archives, the remaining surfaces are dressed with a lighter blue shade.

The topography of the dial incorporates four subdials granting a sense of equilibrium. The functions include a week indication, day, date, astronomical moon, month, leap year, hours and minutes.

The 41 mm case of the Royal Oak Perpetual Calendar has a slender profile with a thickness of just 9.5 mm and is offered in two variants: stainless steel or 18-carat pink gold.

Both case options are hand-finished with satin-brushing and polished surfaces. They are paired with matching bracelets fitted with an AP folding clasp.

The self-winding Calibre 5134 driving this watch measures just 4.3 mm in height. This slender profile has been achieved by re-arranging a number of components including the 22-carat open-worked oscillating weight. The bulkiest part of the rotor is positioned to its outer edge which is recessed within a channel encircling the movement, thereby mitigating height. Likewise, a suspended barrel has provided a further means of reducing the movement’s thickness.

Visible through the sapphire caseback, Calibre 5134 incorporates “Côtes de Genève,” circular graining, circular satin and polished chamfers throughout.
