I did this to a shitty Thorn BB58 homage bracelet and it worked great until i gave it away.
1. Disassemble the bracelet and ultrasonic clean / lightly boil it with a light ammount of dish soap.
2. Dry the parts completely
3. Reassemble with: loctite, vaseline, q-tips, and heat gun. Heat the parts to as warm as you can still hold in your hand.
Loctite the threaded tip, thin layer of vaseline behind it on the smooth part of the pin.
4. After reassembly, put it in the refridgerator for a few minutes. 5min is plenty.
5. Wipe down the bracelet with a microfiber, add a spray of iso-alcohol to remove fingerprint/oil stains and excess vaseline.
You will need to wipe it down again once or twice more over the next few days as some vaseline may leak out, but after that it will be properly lubed and buffered to feel swiss for a while.
