The FB 1.1-2 model in 18-carat white gold stands out in terms of the case itself, since some of its faces are adorned with baguette-cut diamonds. There are four in all: on either side of the crown and alongside the engraving of the limited-edition number facing it at 9 o'clock. The crown is also set and the choice of baguette-cut diamonds evokes the vertical pillar-type construction of the movement beating at its heart.

The FB 1 – Oeuvre d’Or collection features a "pyramid" motif decoration adorning the entire surface of its three half-bridges, an authentic artisanal feat demonstrating the know-how of the Manufacture’s engravers. The material is cut free-hand with flawless precision and regularity using a graver.

The patinated dial of FB 1 – Oeuvre d’Or is created using a combination of engraving techniques that require great manual dexterity. First of all, the gold is finely grained with a graver. The surface is then crafted at length using a tool called a "rocker", enabling the light to glide across the dial to the rhythm of the shimmering reflections of the moiré effect thus created. Finally, the dial is hand-engraved and then subtly coloured to perfect the overall legibility.
