Grail Watch 11: Sartory Billard SB07 “Ghost”

For our latest creation, we’ve teamed up with Armand Billard and the team at Sartory Billard for a one-of-a-kind take on the SB07, the SB07 ‘Ghost’, a sports watch like no other. Every single element of this watch, the dial, the case and the bracelet, boasts a flawless mirror finish that makes this watch feel equal parts timepiece and art object. Building on a mirror dial watch Sartory Billard created back in 2020, the SB07 ‘Ghost’ takes the premise to its ultimate conclusion. Nearly every visible portion of the watch has been painstakingly polished to achieve a flawless finish. Special attention was paid to the steel dial, which was especially complex to achieve.
Armand Billard, founder of Sartory Billard, says that 170 dials were produced to achieve 15 perfect examples. For all that the final impact of these watches on the wrist is far beyond what you’d expect of a steel sports watch, there is no doubt of the bone fides of these pieces. Rated to 100M, with luminous hands and markers, and a highly capable La Joux-Perret movement, the SB07 ‘Ghost’ blurs the line between wearable art and practical object in the best way possible.

Mirror Mirror

There’s absolutely no doubt that the most striking feature of this watch is the dial. The flawless mirror polish is a painstaking process, where some dial elements and notches have to be given a protective lacquer coating before a painstaking process of increasingly finer polishes, resulting in a steel dial that is perfectly reflective.

Modern lines

The 40mm case of the SB07 ‘Ghost’ is far from simple. The bezel (mirror-polished, naturally), has two distinctive insets on each side — a detail that is picked up on the flanks, which are recessed and given a highly contrasting satin-brush treatment, one of the few non-reflective elements of the watch.

Off the Rack

Incredibly, this high polish continues onto the bracelet. Instead of the typical satin finish, this H-link bracelet is entirely mirror-polished on the topside, while its underside is satin brushed as usual so that it is smoother and more comfortable against the skin. Due to the nature of this integrated bracelet the lugs of the SB07 ‘Ghost’ flare, but the design will comfortably fit wrists as small as 6 inches.

Peripheral Power

Visible through the open caseback of the SB07 Ghost is the La Joux-Perret G100, and automatic movement with 68 hours of power reserve. It’s a reliable, no-nonsense movement with one quite special detail. The rotor, rather than being your typical central oscillating weight, this watch uses a mystery rotor, where a sapphire support is attached to a fluted titanium ring with a hidden weighted sector made of tungsten. Ingenious!
