Service: Seiko Lord Marvel calibre: 5740

P1070027

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.

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.

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!

    Hi, Awesome job there restoring the Lord Marvel.
    I have a Lord Marvel 36000 which needs to be serviced or perhaps restored.
    Can you please email me. Just need a quote before I send it over. I am in Canada.
