Vintage Seamaster Cosmic LH Winder

I recently resurrected a stainless steel manual seamaster cosmic that my wife bought for me 50 years ago.
The reason I haven't worn it for 30 years is because the winder has broken off and is long lost.
Now, the local Omega agent said it was going to cost me something in the order of $1500 for a new winder, a new glass and a clean !!! , so before I threw it back in the box I decided to look up a bit more about it.
The main reason I am posting to this forum is because it seems a little different to any others that I have found pictures of.
It is a manual with date on the right hand side.
The winder however is on the other side (left) and all pictures I can find show the winder on the right next to the date.
The markings on the back, from top to bottom, are:
Omega sign, SEAMASTER, Seahorse insignia, WATERPROOF, 136016-TOOL 105
On the front is:
Omega sign, OMEGA, Seamaster (running writing), COSMIC

I have looked a 'womens' versions and they all have the winder on the right also.
The www.omegawatches.com website says that it cannot be found.
It is the same as https://www.omegawatches.com/watch-omega-seamaster-cosmic-st-135-0016 except for the date on the right and the winder on the left.

Can anyone cast any light on the reason the winder is on the left ?

Maybe a picture or pictures of the watch will help?

I will see if I can get any better ones.
Also, I think that what I refer to as a winder is actually called a crown.

I think it's just a turned movement rather than a LH crown?

This is a monocoque case and the movement/dial can only be removed from the front after removing the crystal.

It appears that the movement has been put back incorrectly.

It has never been apart or to a watchmakers - that is how it was bought new.
And if it had been 'turned' how is the date adjustment meant to work?

It can't work because it's missing the crown

The crown on these watches are latch-on, when they are removed the movement can turn inside the case, but it can't turn 180 degrees, it can turn ~40 degrees

However sometimes brutes do whatever with cosmic watches because they don't take time to understand how movement just enters and slids in there, it's simple, but sadly some people are just brutes

So probably you are looking at a watch with a movement very incorrectly jammed in there

But to be honest, I've never seen any LH Omega's, now I wonder whether they exist - it's usually easy to make a regular dial go LH, but a date one ...

AND recall that this is how it was bought NEW (apart from the crown that I broke off in the 80's)

Ah, I'm sorry, I didn't read/believe it to be honest, since 99% of posts are actually querying the state of a potential purchase

Then you just need a $50 crown and a $50 crystal

It's easy to find the non-original crystal on eBay, but the crown is harder to find right

Example:
https://www.ebay.com/itm/114712325713
and
https://www.ebay.com/itm/265073287459

But it's definitely not $1500 - you can buy a cheap tool like this: https://www.ebay.com/itm/231031212994 - pull/break the old crystal out, and push the new crystal with your hands if you are strong enough

Or you could also buy a cheap crystal press too

But all in all, it's like $200 at most considering you buy everything and pay shipping etc. too

BUT, Kaplan, you are right, the movement has moved, at least a little bit as you can see.
I will take it to the watchmaker's in the morning and ask him to take the top off and tell me what the situation is.
I will report back when I know.
Thanks.

Thank you so much for this information.
I'll see how things go tomorrow.

The winding stem just latches onto the crown I sent, but I don't know what crown size is correct for 136.016

Since you have access to the watchmaker, I guess you can ultimately just buy the crown and the crystal for $100 at most and let him press the crystal in there - pressing the crystal to be honest requires some expertise, but all in all, it's a 5 minute task

Correct me if I'm wrong, but I guess the crystal creates friction and keeps the movement in place, otherwise the movement is relatively easy to move like that once the crystal is out

Very unlikely. This will have a Cal. 611 or 613 inside, and it would require a custom printed date indicating wheel to make this into a left side crown model. If you can have the watchmaker take photos once it's out of the case that would be good. My guess is that you will find the winding stem (that the crown attaches to) is on the same side of the movement as the date window.

If this has never been serviced, it will need it for sure.

Thank you all very much.
JimInOx and Kaplan were right.
The movement HAD rotated in the case after the crown and stem were broken off.
Now I will get a new crown and female stem and a 32mm crystal and the watchmaker will put it all together.
Thanks again
