Omega Seamaster Overhaul.

[ibby7]

I recently acquired a Seamaster on here that was in pretty bad shape and took it on as a challenge to overhaul it as best as I could.

For the spirit of the Mods forums I will post some before and after collages and a few pics

I hope you enjoy them.

Cheers.

The watch arrived like so, The faded bezel was testiment to its service on the wrist of the previous owner.



There was a thin film of grease in the majority of the movement and some oxidation on the barrel as well as the screws so they needed to be replaced IMHO.



Movement cleaned and serviced and new parts fitted, including train wheels.





Anyways, here are some before after pictures




The bezel insert is not pushed down fully on this pic but was rectified later on.


Caseback originally had the letters M.L engraved





The amplitude and timing where very poor during service, I soon dealt with that with no problems. (Before is on the bottom and after is on the top).



Sorry it wasnt a more in depth view of the service and refurbishment.

Thanks for looking.

Interesting and thanks for posting. You've really transformed that one :-)

What methods did you use to refinish the bracelet - especially the clasp?

[Megatron]

thanks for posting that - it's like 2 different watches! I'm very envious of your skills - the end result looks great and must be very satisfying!

mouse,

The bracelet was finished on a specific polishing machine with a variation of abrasive mops to get the result. Sorry I. Ant post pictures of the machines as I don't own them but only have access to them. It is possible to achieve a close(ish) finish by using a garryflex block on the clasp.

Thanks for that. I suspected it was machine finished, but thought I'd ask. Nice work.

Very nice transformation... You service it Yourself?

Yes the movements are great to work on, even more so, when you have spare parts to hand.

You can see the difference in the average gain in all positions in the timing tickets.

Thanks for that Abe and thanks for replying at my PM... Will definitely keep You updated.

What's the most likely cause of low amplitude on these? I was discussing this last week with a 'watch god' (BHI tutor).

I`ve come across a bent train wheel bridge twice on these, probably caused by heavy-handed work in the past. The only drawback I see with these movements is the somewhat fragile construction, they don`t take kindly to monkeys working on them.

Personally I love 'em.

Could be a range of things. Could you imagine if they still made wheel pivots properly by burnishing them rather than chemically burnish them in the thousands at a time.

I work my way down from the barrel to the escapement fault finding as I go along. Train jewel flatness can be a stealth problem when hunting a low amp fault.

[walkerwek1958]

Cheers Ibby, I`ve got one at the moment that's not running as I`d like it to and I'm fairly sure it's another train wheel bridge that's slightly out. Replacement is in the post. Hadn`t thought about the jewels not being flat or the surface finish on pivots.

Thanks for posting. I recall seeing this for sale a little while back.

Great to see you breathe new life in to it :)

Is it a blue or black dial? Can't tell on my phone.
