Dear members,

I am new to this forum and have a question about my 145.022.
Was it common to change case backs and dials?

I have 'flight qulified' case back, signed 145.022-76 in it and a non step dial.

The extract from the archives says it was built in April 1971.

Some pictures below. If you guys need any further just let me know.

Thanks & krgds,

Jan

What is the actual serial on the movement? Sometimes the Extracts have a mistake or there was a typo when requesting it. Double-check everything.

It seems likely that you have a watch with service parts, or that has been put together from parts.

Can these parts somehow be put into a time frame.
Are there specific things that idicate a year of production?
Esp. for the dial 😀
Thank you 😀

Visually the watch reads as -74 or -76. Are you sure the serial is not 39m? As that fits what you see on the watch.

Dome dial, and dial font is 74 through mid 77 production. It’s possible it was serviced in 76 or77 and got a new caseback as well.

Yes I am sure about the movemment reference.
I had the watch open at my local Omega AD that I can take a pic of the movement.

First of all welcome and congrats for your nice Speedy! 😀
We are talking of vintage pieces, over time even the oddest event could have happened because of service or problems occurred for usage..also those events are part of their own historical value affecting it positively or negatively depending on the case. This might be a case of movement swap or even something more (for example the hour hand seems to be different than usual), but you still have a nice and also rare dial, a nice DNN bezel from 70s, a not common -76 caseback, a 1971 movement which is always valuable and even an original glass..the sum is a nice and also valuable vintage Speedy to be enjoyed..and according to me, that's what really matter! 👍
Cheers 😀

Not to forget the original 1171/633 bracelet 😀

Never noticed that the hour hand is as it should be.
Which reference are they usually linked to?

I see no issue with the hour hand for an 861 piece made between 1969 and 1999. Color is as expected for approx date of early-mid 70’s.

If the serial is correct, at best it received a service in 1976 or pre sept 1977 and got a new caseback.
At worst it’s a movement from an earlier watch placed into a new case. Curious as to the movement there is a possibility that there is a clue in that.

The hour hand looks a little suspect to me. The taper seems a bit more blunt than I'm used to seeing.

Adding caseback and movement
Is it me or does that look like 2 different watches?? I mean pretty conclusively those are 2 different watches.

the scratches and lug wear does not appear to match.

A pic from just a second ago. It is the same watch on all pictures
No it’s not. The first caseback shot is clearly a different watch. Medallion wear and amount of black paint is clearly different.

Very interesting.

I had a very similar watch that was only a few hundred numbers apart. 145.022-74 caseback.
Dome dial. The extract also showed April 1971 production...

Isn’t yours a step dial?

No you are wrong, sorry. 1st pic was taken on my way from work in a train with kind of „blueish“ light.
The watch was since then always in my home and it is 1000% the same 😀

It looks like the same watch & caseback to me.
It's hard to tell because the first picture is very blurry and both pictures are taken from slightly different angles in different lighting conditions which might show the wear differently in each one.
