Part 3: Casing of the watch and final steps

Welcome to the final step in your watchmaking journey. This time we will show you how to install your watch in your case and close it all up. As always we have a full video instruction available:

 

Time to case your watch. Firstly we have to remove the dummy crown that is currently placed in the movement. Pick up your movement with two fingers right under between the crown and the movement and hold the movement with the remaining fingers. Carefully push down on the little dent that is marked in red below and (while pushing it down) push the crown out with your fingers. You wont need much force to do so, but if you feel stronger resistance instead check that you are still pushing down the lever.

Next up is the installation of our movement into the case. Take your case and remove the casing crown by unscrewing it. Then remove the back of the case by turning it with the friction ball until it unscrews. Remove the white plastic movement holder ring (you will need it later to secure the movement). Place the back cover with the opening down on a clean surface. Now to the main part of the case - clean any debris and dust with your dust blower and Rodico. Be careful not to leave fingerprints inside the case, which be difficult to remove. 

If you are satisfied with the case, place it similarly on a clean surface with the opening downwards. Before we install the movement, make sure that your dial is similarly clean of any dust or debris. Use your dust blower and Rodico to remove any visible dirt. 

The casing

Finally we can move our movement into the case. Take up your case and place it over the dial. It should sit evenly on the dial with all markings visible. The crown should be at the position of the date window (3h).

Slightly press the case down against the movement cushion, lift up the entire cushion  and carefully turn it over. Your movement now rests inside the case, however it is still unsecured and needs to be handled carefully. 

To secure the movement, push your real/casing crown into the case and into the movement. You don't need to screw it in for now, but the crown stem keeps your dial in position. Finally we can install the movement holder. Take up the white plastic movement holder and check for the upper side which has no cut outs. The downward side has several cut outs including the one for the crown stem linking into the movement. Opposite from the crown opening you will notice a small plastic hook (red circled below). Now we know how the movement holder ring is installed - the cut out side is facing inside the movement, the plastic hook faces away from the crown and towards the matching recess in the case (marked in red). 

Place the movement holder between the movement and the case. Be careful to place the plastic hook into the recess and press down equally around the movement. Your movement should now be fairly secure and not move around the case.

The last step is to close up the case. Firstly place your case back onto the case and slightly screw it in by hand. Turn your case around, check if the dial is correctly aligned and that no dirt is visible. If you are satisfied push down your crown fully into the movement and screw it into the case. Again control if your hands are moving freely. 

Finally we can close the case for good. Take your friction ball, place it on the case back and screw it in. There is no need to use excessive force, as you have a gasket inside the screw case back and screwing the cover in too tightly might actually damage the gasket. It should be too tight to open with your hands, but not much more. 

Wristband installation

Our case is closed, our watch is working and we only have one thing left to take it our for an excursion from your bench. We only need to install the wrist band. 

All our bands are delivered with quick release spring bars, so you won't need any tools to install them. Take up one side of your wristband and you will see a small metal lever at the spring bar. Pulling it back, also pulls back the end cap and allows you to install the wrist band between the two lugs. Finish up your second side and you are all good to go!

I hope you enjoyed this tutorial and the experience of building your own automatic watch. If you have any questions or if you are stuck at any step along the way, please feel free to reach out to me via Email (Felix@Fink-time.com) or via the contact form.
