Halograph Tourbillon Collector's Edition Emerald

The Halograph Tourbillon is the ultimate Xeric watch. The dial features our innovative signature split display and halo hands which float over the arcs to encircle the time. The inner arcs display the hours and the outer arcs display the minutes. The time can easily be read through the two halo hands. As the halo reaches the end of its track, a new halo appears on the opposite side. At the 6 o'clock position you see the balance wheel oscillating back and forth inside the tourbillon cage, which acts as our seconds indicator as it makes one full rotation every 60 seconds.

You may be asking, what is a tourbillon? One of the most challenging things watchmakers faced when regulating a mechanical movement was the effects that gravity plays on the caliber or movement. Originally developed by famed watchmaker Abraham-Louis Breguet in 1801. Breguet’s solution was to create an escapement that was constantly in a state of motion.

Tourbillons are arguably one the most difficult movements to make by hand. The escapement (hairspring, balance wheel, and pallet fork) is housed in a rotating cage that, because of the constant motion, averages out the effect of gravity when the watch is in different positions. They require a special set of tools and a lot of time to make. The tourbillon mechanism is tiny, weighing in at under a gram, and is usually crafted with more than 40 parts, finished by hand and made from lightweight metals like aluminum and titanium.

The straps are made using premium, full-grain leather from Horween, one of the oldest continuously running tanneries in the United States. The clasp design is the same used on high-end luxury watches. Unlike basic deployant clasps, the Halograph Tourbillon clasp allows the end of the long strap to slide between your wrist and the underside of the short strap so no extra leather keepers are required. The strap also has a built-in, quick release springbar system allowing you to swap out different straps for any occasion.
