Trace Line Clock

I always want to look time in new ways.

I want to create my own watch design.

So this is the watch I've newly created.

The minute and hour hands are connected by a single line, constantly shifting to new angles and lengths as they trace the passage of time. The constantly changing hand make it Every time you check the time, you see a fresh, new perspective on the hour, making it truly captivating.

The inner edge of the hand rotating along the inner circle indicates the hour, while the outer edge of the hand rotating along the outer circle indicates the minute.

The minute hand moves faster than the hour hand. Therefore, the hand moves outward in a large circle, using the hour hand as its reference point. This is why the length and angle of the hand constantly change.

Clock movement and hands

Magnets [2x1] 1 piece, [2x3] 1 piece, [4x2] 1 piece

A small amount of 0.7mm iron wire

A candle to smoothly lubricate move

I completed all tasks using AutoCAD and Inventor. All numerous prototypes were modified using Inventor.

You can download the 3MF file I uploaded. And you can add a brim or raft according to your environment.

I assigned numbers to each part. Check them here in the image and use them as a reference when you make yours.

Install the movement onto ①. You must loosen and tighten the movement's nut.

Making Inside Hands.

Apply adhesive to ④ and ⑤, then insert the magnet. Since small magnets are hard to insert, using scissors like a press is convenient. Cut the hour and minute hands purchased with the movement into a circle.

Then insert the minute hand into hole ⑤ and secure it with adhesive, and insert the hour hand into hole ④and secure it with adhesive.

After that, you can insert ④ into the movement, and you can also insert ⑤.

Sand the back surface of ②. Since it's a printed object, the surface is rough. then Apply candle wax to the entire hemisphere. Apply candle wax to the large circular section of ② too. This is to help the hand move smoothly.

Then assemble ② onto ①.

Making Outside Hand.

Attach the 2x3 magnet to hole ⑥ with adhesive. At this point, verify that the magnetism of the hour hand is properly aligned. If misaligned, the two magnets will repel each other. The magnetic part will be connected to the hour hand.

Cut a 0.7mm iron wire and attach it to the long groove. Then lightly sand it down. Apply candle wax to wire and magnet. The wire will be connected to the minute hand.

Then place it on top of ②. It will align with the magnet in the Internal Hands.

③ is like in the photo, sand it down to a smooth finish and apply it with a candle. assemble ③ onto ①, and you're done.

Then attach the lid ⑦ to the back of ①.

If the watch is not functioning properly, check the following items.

1. When inserting the hands into the movement, check whether they are inserted too low or too high, and adjust them to the proper position. (Even if your and my print files are identical, slight size differences may occur due to environmental factors.)

2. Bend part ② slightly. (This is because printing may cause shrinkage or expansion due to heat and temperature, resulting in imperfect leveling.)

Now this is yours.

Thanks for reading, and enjoy!
