Lay out all the parts from your Make My Own Watch Kit and check with the parts list to identify each component. Remove the movement from its protective case and place it into a movement holder.
Attach Dial onto Movement
Line up the dial feet into the corresponding holes on the movement, make sure to orient the movement so the hole for the stem is in the 3 o’clock position and lined up with the date window. The dial is held onto the movement with the dial feet, which friction in. One or both feet can bend, if that happens you can use pliers to gently bend them back.
Cut the Stem to Size
The stem that comes in your kit is too long for the watch and needs to be trimmed to fit properly. The stem needs to be trimmed down to 15.15mm in overall length. Before cutting the stem you will need to measure out where you will mark and cut the stem. Measure the stem and using a sharpie or piece of tape and mark just outside of 15.15mm. *You don’t want to cut the stem too short. Your kit came with two stems in the event the first one gets cut too short or damaged.
Here are two methods to cut the stem to size. First method is using a digital caliper (not included with the Make My Own Watch tool kit) and the second is using the gauge that is included with the tool kit. Use a marker or piece of tape to mark where the stem needs to be trimmed to.
With the digital gauge, open it to 15.15mm and lock it with the nut so it doesn’t move. Use tweezers to hold the stem over the opening with the threaded side going over the top of the jaw. Mark the exact cut location with a sharpie or piece of tape at the jaw opening.
Insert the stem into a pin vise and use a side cutter, shear or end cutter (included with the tool kit) to cut off the excess where you marked the stem. Be careful no to cut too much off, as a stem that is too short will not work properly. You can always cut more off the stem if it is still too long after the initial cut. After you cut, there is often a fragment of metal left, use a file or piece of sandpaper to smooth the end of the stem. File the stem with the end perpendicular to the sandpaper for a flat, even finish.
If the stem is too short, you may hear only one click, no clicks or it may not stay in the movement. You will need to start over with a new stem.
If the stem is too long, the crown will not sit flush with the case when pushed in. The watch will still function normally but you risk dust and water damage without the proper sealing. Remove the stem, file it down slightly on the threaded end and try again.
After you confirm that the crown sits flush and the stem is the right length, remove the stem from the movement. Release the stem by pressing down on the set lever dimple. The stem must be pushed all the way into the movement before you can remove it. The dimple will appear behind the 4 o’clock position.
At this point, you know that the stem is the correct length and the crown is attached to the stem. You can take the movement out of the watch case and are ready to install the hands.
Align the Hands with the Date Change
With the movement and dial (together without the hands installed), insert the stem and crown into the movement. Push the stem and crown all the way in, then pull out on the crown to the second click and turn the crown clockwise until the number date starts to change. When the date is between any two numbers, stop turning.
Align the Hands with the Date Change
Start by installing the hour hand first (the shortest hand with the largest mounting hole). Pull the crown out to the second click to stop the hands from moving while you are trying to install them. Place a dial protector to prevent scratching; using brass tweezers gently place your hand at the 12 o’clock position to match the date change. We want the date to start rolling over to the next day around midnight.
Once all the hands are installed make sure they don’t touch each other and are all parallel with each other and the dial. You can bend the hands slightly with tweezers if they are touching or angled. Be gentle as the tweezers can scratch and bend the hands.
You can check the hands alignment by pulling the crown out and turning a few rotations. Push the crown in and wind for two rotations and watch that the second hand rotates freely around the dial.
Remove the stem and crown assembly from the movement using the set lever and set aside.
Place the Movement into the Case
Place the movement in the movement holder upside down so the dial is face down. Clean the inside of the case with a microfiber cloth and/or dust blower. You want to make sure there are no fingerprints or dust specs inside the case before placing the movement inside. Once the watch is sealed up, you want it to stay clean.
Place the dial and movement into the case with the dial facing the glass. Make sure to line up the date window of the dial with the case tube on the case.
Place Movement Ring into Case
Put the movement ring over the movement into the case. The ring has a cutout that must be aligned with the stem and the opening of the cutout must be facing the dial. If you are not careful about aligning the cutout with the stem, you can damage the stem or case tube when installing the movement ring.
Gently press the ring down until it is even with the case on all sides. It should be about the same height as the movement when it is fully in place.
Put the Gasket on the Watch Back
Lubricate the case back gasket with silicone grease. When lubricated in silicone grease, the gasket will last much longer and be much less likely to leak, keeping your watch movement moisture free. It also insures that the gasket will not be damaged when the back of the watch is screwed off and on for repairs or upgrades. Do not use excessive grease, only a light layer is needed. Do not grease the case or back or other components.
An easy way to apply the grease is to put a small amount of grease on a paper towel. Use the paper towel to grip the gasket and pull the whole length of the gasket through the grease.
Slip the gasket over the side of the case back lip, hold it in place with your thumb. Then, using your index finger and thumb of your other hand, stretch the gasket slightly to slip it around the rest of the case back and fit into place.
Screw Case Back On
With the gasket lubricated, the back is now ready to be put on the watch. Place the watch into a watch case holder and put the back onto the case and tighten it. Hand tighten as far as possible, then use a JAXA wrench or other closing tool to turn a 1/4 to 1/2 turn to make it tight. You don’t want to over tighten or it will be a much harder job getting the back off when a repair becomes necessary.
Holding your watch with the watch back facing you and the crown pointing to the ceiling, place the end of the spring bar from the band half with the buckle into the hole on the bottom lug. Be sure that your watch band’s finished side is facing the same direction as the watch face. Take the forked end of a spring bar tool and push down on the spring bar to compress it. You can use the spring bar tool to slide the spring bar under the lug and find the hole. Move the watch band around in the lugs until you feel and see the spring bars pop into place.
Set the time
The time is set by using the crown at the 3 o’clock position. It has two setting positions, first click and second click. To change the date pull crown out to position 2 and turn clockwise until the desired date is reached. Pull the crown out to position 3 to set the minute and hour time. This will rotate both backward and forward to set the time.
After setting the time be sure to push the crown all the way back to position 1 to seal the watch from dust and moisture.
The mechanical movement in this watch is automatic and doesn’t have or need a battery. By wearing the watch, your movements throughout the day keep the watch wound and running normally. If you don’t wear the watch everyday, winding it manually can keep it running. Wind the watch manually with the crown; while it is fully pressed in, rotate 20-30 times in both directions. When you’ve wound it enough to get the watch running, wear the watch and the auto winding mechanism will continue to wind it for you.
