Hello all,

It has been a while since i poked my head into this forum. I hope everyone is doing well.

I went to the Miami antique show this afternoon and of course i came back with something because i cannot help myself Found this at a reputable estate dealer (my friend who works at auction houses was with me and he knows the company). The watch ticks when wound but the item description said movement would need fixing. The case is white gold apparently not stainless. The acrylic crystal is scratched but i was assured it is an easy fix. Overall the watch looks really original and unmolested (also unserviced, let's face it). I plan to have it fixed, cleaned up and use it for a while before i decide if i want to flip it back out or keeping it.

I understand that the Cal.620 is not an uncommon movement, so how hard is it to find parts for this watch and how much would a watchmaker want to fix it?

Here are some photos:

 

You really need to ask a watchmaker after he has pulled it apart and had a good look at it. Just looking at a watch will not tell you much.
Find a reputable watchmaker with a Omega parts account and let him at it.

Would need the model number to see what you have.
Any hallmarks on the outside of the case to indicate white gold ?

 

There is a mark on the caseback that says 14kgold. Here is the bag that it came in that mentions the non working spring.

 

Any decent pics of the back of the watch?

 

Looks like an American cased dress watch. Is that a small lip on the back opposite the 14K marking?

The 620 isn't all that rare so I'd imagine parts are available if any are needed.

 

From my (limited) experience and the information from Omegastar’s excellent article on here i’d say that the watch probably has a genuine buckle going by the shape of the Omega symbol. Thats assuming the marks on the back match up. Thats a nice bonus at least

 

the back of the buckle says "depose swiss".

 

This Article is very informative about buckles and helped me a lot. You can check the markings of your buckle there:

Thanks Pedro!! I found it identical to one of the AW buckles shown in the thread.

 

So i called my local Omega boutique. They will take in the watch and make it like new for $650. Not sure it is what i want (or even what i want to pay for that matter) but that is one option.

 

Don’t do that ... they will destroy its collector value. All you need is a movement service from a good watchmaker.

 

620 movements can be picked up for next to nothing. That calibre was more usually found in ladies watches so lots have men melted down.

 

That Omega service will also exceed the resale value of the watch.

 

So it turned out the watch didn't need much. Went to someone referred by the same friend i went to the antique show with. He buffed out the scratch on the acrylic crystal, opened the watch up and fixed a couple of loose screws and the watch is winding and running. Looks like the watch has never ever been serviced in its entire life (no markings inside case) and the movement was still shiny and new-looking. I had the strap replaced (and buckle-swapped) and it is keeping time.

Cost: $20

 

So you're running a 50 year old watch that has never been serviced

 

He offered to refinish the dial, but i don't see the need. It is pretty perfect as it is.

 

I will service it soon. I promise. and ouch.

 

What you are doing is akin to running a car engine without oil.

 

Nice looking minimalist watch.
