My machining experiences between 7075 Aluminum and Gun metal bronze to the Juntor watch

Gun metal juntor machining experiences   What a beginner most afraid when starts to machining are three things, the sound, the smoke and the sparks of the contact of the tool with the work material. With respect to sparks, when using titanium or magnesium alloys there is a great danger of ignition, which means that apprehension to them must be watchful. In any case, that is no problem in the aluminum and bronze alloys that we currently use in the Juntor. Although in the old Juntor we use alloys of steel, titanium or bronze to aluminum, we are now opting for aluminum and bronze alloys of tin called Gun metal, since the current Juntor has a marked tactical component. Loud sound in machining appears when cutter has a large diameter. This is because cutting surface increases. So cutting deeper, faster and more feed surface of the workpiece on each step sound increases. If the beginner is not get used, it will seem that the machine bursts. For veterans this sound is a music to their ears. At the beginning I recognize that I was very afraid to machining. Now the sounds helps me to know that I have to decrease the cutting speed or change the milling cutter. Smoke is exactly the same. It frightens when you do not know what the matter is. It happened a couple of times because I measured wrong tool length. With excessive friction of the tool to the metal in the area without cutting. That is a big problem when machined brass because it can change the color of the piece and darker. If...
We should recover the private area for EXT customers

We should recover the private area for EXT customers

We should recover the private area for EXT customers.   In 2006, when we introduced our website we developed a private area for our customers. The clients could access directly from the our website and it included several sections: – Guarantee: Clients had access to the conditions of the guarantee and the expiration date. – Contract: Included the technical specifications of the EXT watch acquired and he could download the invoice if required. -Technical service:  Customers could contact directly with our technical service, creating a notifications history, like o-ring changes, new straps, bezels of different colors, etc. – Newsletter: EXT customers received a quarterly newsletter about our unique way of feeling time. – Notifications: A notifications history for each customer to the brand or us to them. – Forum: EXT customers from around the world could be in touch with each other through a forum relationship.  They could participate in various topics related to time or the way we live life in Spain. – Merchandising: Customers could acquire different accessories like straps, links, bezels, shirts or glasses. By that time we found it a very attractive idea, because if a customer pays a high price for a watch, likes to have an interaction with the company. Unfortunately the area was not successful at all. We thought that the problem was that the idea was very ahead of its time. Now that social networks and the Internet are booming, this private space should be recovered again. As well, we are ready to make things, we consider that this is the moment to re-start  this area. We realized that there are a lot of posts explaining this idea, looking for an added value to a product. We were...
A list of the innovations we have introduced in the Juntor

A list of the innovations we have introduced in the Juntor

  A list of the innovations we have introduced in the Juntor The Juntor is a watch that we have been developing for several years, and therefore, has improved considerably since its first version (Old Juntor in English). This post is a compilation of the most important innovations we have incorporated into the design, development and mechanization of the Juntor. Almost all parts (except the swiss movement) are made in our workshop in Alcoy (Spain) The Juntor design is based on something as simple as the shape of a nut. On this basis we developed a design that suppressed the watchcase legs. The watchcase legs are very uncomfortable especially in watches that their size exceeds 40 mm. The legs were replaced by screwed plates to back case, with two pivots that are inserted inside the belt. This allows a great attachment to the middle case and the back case. These two pieces are machined with niches or channels that allow the lodging of the belt in a very precise way. The watch bezel is rotating with twelve concave perforations, with a width of 0.4mm which is exactly the size of the ball of the pushbutton. These upgrades have been designed to support the watch bezel just in the numbers where the concave perforations are located. They allow great stability and a smooth and firm rotation of the bevel in the middle box. The hexagonal shape with the corners in cantilever allows a perfect grip of the bezel when rotating. The bezel has a titanium-molybdenum support spring allowing it to maintain the shape permanently and expand with body temperature. This...
Why I make my own design watches

Why I make my own design watches

Why I make my own design watches At first it may seem very easy to create a brand of watches but it is very difficult manufacturing. Most of the young companies that appear on the market look for an already cataloged watch. They print their logo and sell it after. Having a good online store and a good SEO positioning will be, for sure, beneficial. It is currently, the most common business model. It is a challenge, designing, developing and manufacturing my own design watches. When I created the EXTático brand, I conceived a fairly ordinary design with an idea of time called Spanish Time. Over the years and the experience, I changed the idea on the design. Now the watches I design and produce are based on forms of industrial elements. I learned to design and develop my own design watches using Autodesk software. Currently I use Fusion 360, which is perfect for companies like ours. The advantage of Autodesk Fusion 360 is that it is a software for incorporating machined in 3 to 5 axes. That encouraged me to create my own watch-making workshop together with my wife. We bought a CNC ( Computer Numeric Control) together with a milling machine. As well as other machinery such as a sandblaster, a polisher, a pad printer machine for dials, etc. For more than a year we are in a continuous process of an every-day learning on how to handle and work with the machines to deliver an accurate product. We are also in the stage of manufacturing the prototypes of the Juntor model, which is proving quite complex. Nevertheless,...
How the Juntor concept started. Working in Spain.

How the Juntor concept started. Working in Spain.

How the EXTatico Juntor Spain concept started. More than ten years ago, we began our journey through this world of watches. After the first model we did, now discontinued, we did a twist to the EXTático idea. We went from the idea of the Spanish time to the design of our watches in a conceptual way. The design bases on industrial objects shape such as cars, airplanes, engines or their components. Thus, we designed concepts of engines like the Wankel rotary engine or a Bentley alloy rim. We also inspired in a concept car, the Seat Tango for our Diver or a regulator for oxygen cylinders as the watch bearing the same name. The Juntor was something simpler. We based on basic shapes of bolt and screw connectors. We followed by the idea that a simple screw is a connector of different parts and components, forming complex objects. The simplicity of its shape but the great task that it fulfills, it is a minimalist maxim, less is more. The concept began as a threaded nut with slots and grooves. The Juntor concept was of different materials such as steel, titanium or aluminum bronze. It was 18 mm of height and a considerable weight. It is the old Juntor, that although it is discontinued we think of to make it again if the people asks us it. After the Juntor evolved, keeping its original lines, to a tactical watch, where the bezel turns and the dial is more complex. Currently the Juntor is of anodized aluminum of four colors, blood red, military green, navy blue and gray slate. It is also...
Starting making EXTático watches with CNC

Starting making EXTático watches with CNC

watches, cnc, started My wife and me we have started to make our watches in our own workshop. In Spain we make EXT watches with a CNC machine. Also,we have bought diferent devices like sandblaster, polisher, paint pistol for watch dial. For that we did CNC training courses as machining as micromachining with HAAS Madrid From some months ago we have fulfilled your dreams, to manufacture our own watch designs. We make each watch part here, less movement, but we want to make it in short terms as well. So far we have made a lot of samples in order to reach a high end watch. Aluminium Juntor is a very nice watch based on tactical military esthetic. We hope we can introduce this watch as soon as possible. It is very difficult to get a good watch in a plenty market with so competence. But we are happy with this idea and we will do it. In the picture my wife and me the first day we turned on CNC machine. We have more than 200 prototypes better and...
