Another very cool watch was sent in to be restored! This time a Seiko Lord Marvel 5740-8020U. It’s got a broken mainspring and the case is a little rough!
The movement looks great. I love the micro regulator! I start with sending the case off to Replateit in Canada.
The dial and hands.
Here you can see the winding/setting mechanism after removing the dial.
I start taking the base movement apart. Plenty of cap jewels in the gear train.
Here you can see the gear train layout.
As suspected the mainspring was broken! Wow I always love a jewelled barrel lid!
Not to worry I have NOS mainspring ref#401-431
Movement has been cleaned and is ready to be put back together.
I see that the balance moves freely.
Gear train comes back in place.
I see the gear train moves freely.
I fit the balance into the movement and it’s ticking again!
The dial and hands go back onto the movement.
Movement goes into the newly restored case and looks super!
A great looking watch. The quality of a Lord Marvel movement is very close to the Grand or King seiko!
