Casio F91W Led Modification and Nato Strap Adapter

In this video you can see what a struggle it is to change an LED in Casio F91W. My soldering skills are close to 0 and $5 USB soldering iron was not the best choice. Despite that I managed to do it. Anyone who has no alcohol dependence or parkinson's should be able to do it this mod.
The final result was not as great as I expected. Definitely better but next time I would use LED brighter than 0805.
I also tested nato strap adapter which is 3d printed and you can find a link bellow:
