Overview
 Series 1 This hand crafted timepiece is manufactured in the spirit of traditional watchmaking. For this reason, every major component of this piece was in-house manufactured by hand. Handmade means that only a manual milling machine, manual lathes and other traditional watchmaking tools and techniques are used in the manufacturing process. The reason I am manufacturing everything by hand is because I believe that a hand crafted product has a certain charm and character that cannot be achieved with automated machinery. In my opinion this is especially true with such a complex and beautiful product as a wristwatch. With this product my desire is to present a one of a kind handmade wristwatch for collectors and watch enthusiasts who appreciate the dedication, time and craftsmanship that goes into the making of each timepiece. Due to the extensive manufacturing time of over 350 hours, the production of this watch is limited to a maximum number of 4 pieces per year. (Various components of this watch can be fully customized, for further information please feel free to contact me.)
Manufacturing Process
Movement: I based my Cal. DL-S1 in-house made mechanical movement on the Swiss made ETA 6498-2. It is a seventeen (17) jewel manual winding mechanism, with an operational frequency of 3hz, (21.600bph). The movement measures 36.60mm in diameter, 4.50mm in height and offers a power reserve of around 47 hours. The mainplate, barrel and train bridges are all made of German silver while the pallet bridge is made of stainless steel. The canon pinion, hour wheel, crown cover plate, piece number plate, click and click spring are also hand-made of stainless steel. All of the bridges are angled by hand, and received a circular finishing. The ratchet wheel is decorated using the glashutte style snailing technique, while the mainplate received a perlage finish.
 Case: The case measures 43.00mm in width and 10.00mm in height (with crystal), and It is handmade of stainless steel. The lug width of the case is 20.00mm and it is hand polished to a satin finish. The glass on the top is a 1.00mm thick sapphire crystal with Anti-Reflective coating on both the inside and outside surface. The see-through case-back also has a sapphire crystal without Anti-Reflective coating. The case-back is held in position by six stainless steel screws.
Crown: The handmade crown is made of a single piece of 7.00mm thick round Stainless Steel bar. After the turning, boring and drilling operations are completed, the crown is engraved using a diamond tool bit to provide a better grip for the winding of the watch. It is hand polished to a satin finish to match the case.
Dial: It is completely handmade using stress released brass. The three dimensional design is achieved by precision machining and engraving. Each engraved line represents one minute on the dial, this design produces a unique watch face that is attractive and easy to read. The chapter ring and the name inserts are made of polished stainless steel. The brass part of the dial is black DLC coated. The name is engraved into the small stainless steel plate using manual tools. The letters are 0.90mm in height.
Hands: The stainless steel hands are 0.40mm thick and they are completely hand crafted. I designed their shape to harmonize with the dial and to make time reading pleasant and easy. The hands are tempered, flame blued and hand polished to a mirror finish.
Buckle: The buckle is made of a single piece of 2.00mm thick Stainless Steel and it is suitable to be used with an 18.00mm wide watch strap. I designed its shape to be simple and to harmonize with the overall design on the case. It is hand polished to a satin finish to match the case.
Leather Strap: The in-house made leather strap measures 20.00mm in width at the case and 18.00mm at the buckle. it is completely handmade using locally sourced leather from a specialist supplier. The strap is hand cut, hand stitched with saddle stitching technique and the edges are hand finished. The type and color of the leather and the thread color can be customized.
Presentation Box: The presentation box is manufactured in-house, and it is made of black walnut wood. The box is made of two solid pieces of wood, which are held together by two stainless steel hinges on the back. The name is engraved in a polished stainless steel plate on the top of the box, while the series name and piece number is engraved into a plate inside the box.
