The legendary SR-71 Blackbird. It holds the record for being the fastest jet aircraft in the world and it has never been shot down, simply outrunning any other aircraft or missile threats. It was able to cruise at over 3 times the speed of sound and this in turn generated extremely high temperatures. To solve this, titanium was used extensively throughout the entire aircraft.
We are excited to announce the ZX-8 Limited Edition with an actual mission flown SR-71 Titanium dial. The dial has the original finish from the actual part and we have deliberately left all the marks, scratches and leftover paint on the dial. Hence, each and every dial will be different. The titanium for this dial is CNC cut from a 'turkey feather' of an SR-71 and it was changed during regular maintenance. This was obtained from Daniel Freeman, Supervisor and Chief of Metals Technology for the 9th Reconnaissance Wing. Through his career he has worked on the SR-71 Blackbird, U-2 Dragonlady, KC-135Q Stratotanker, and T-38 Talon aircraft.
Creating a dial from such incredible material proved extremely difficult. The titanium is a Grade 6 alloy, much tougher than the usual brass that most dials are made from. We had to CNC cut the dials to size using carbide cutters, incurring much more cost and time as compared to stamping a dial from a brass blank. The next issue was getting the dial down to a required thickness of 0.4mm instead of its original 0.7mm. We wanted to preserve the original finish of the titanium, hence grinding it on only one side caused an uneven surface which was not ideal for a watch dial. After numerous and expensive failed attempts, we finally created the first SR-71 Titanium dial.
The ZX Project
We wanted the ZX series of chronographs to pay tribute to the X-Plane project. The first case drawings drew inspiration from the X-15. The stubby, angular lugs of the ZX timepiece are reminiscent of the X-15's wings. The short lug length of 49mm makes it comfortable to wear for any wrist size, despite the seemingly large 43mm diameter.
The dials were influenced by the chronographs of the 1960s when the X-15 project was conceived. These dials were given a modern twist with the use of applied indices and subdials. A 2-layer dial is created to offer a sandwich effect, and this lower layer is painted with BGW9 luminous paint. We aim to achieve the brightest glow possible through the use of BGW9 lume, with some models having fully lumed subdials as well.
The 'Rocket' shaped hands and 'Nozzle' crown are custom designed to complete the entire timepiece. These touches are what sets the ZX series apart from other timepieces.
Materials were also an important consideration when designing this timepiece. Titanium is an important material used in high performance aircraft and we wanted to use this for a case. It offers a wearer increased comfort due to its light weight without any loss in strength. We also chose to brush and polish the titanium case, resulting in an elegant look to titanium instead of its usual matte sandblasted finish. Ceramic bezels are available on certain models due to its high hardness as bezels tends to encounter the most abuse.
The ZX Automatics are powered by the proven and reliable Swiss made Valjoux 7750 movement. The 7750 has seen decades of service in Swiss watches from the $1000-$10000 range. This will come in Elabore grade which offers a great view from the back.
We are also offering theZX series in a Seiko Mechaquartz movement. This is meant to make it more accessible in terms of price, as some might find a Swiss 7750 too rich for their budgets. A Mechaquartz movement runs off a Quartz crystal, but combines mechanical chronograph module. This means that the chrono second hand sweeps smoothly, along with a sharp reset function just like you would find in the 7750.
