What about my 135.020 SP . Omega De Ville . That hasn't got any pushers ? I thought it mean stainless plated ? . But that doesn't work on the 145.012 SP

 

Could the case back be for the plated speedmasters ? At first and then used as service parts ?

 

Just to add another data point here, I looked up the 145012 and SP versions on the Extranet just to see what differences there are currently (I know this is possibly quite different from what they were originally).

Right now the case back seal, crystal, and pusher part numbers are all the same between the 145012 and 145012SP. The only differences for water resistant parts are the case tube and crown.

145012:

Case tube - 090ST0017

Crown - 069ST43018

145012SP:

Case tube - 090ST0005

Crown - 069ST43069

The 145.012 has a 321 movement and the 145.012SP has a 861 movement

 

Completely wrong mate.

 

I already asked this question few years ago to a well know and famous book author about speedy, and i think the answer was SP = Special band That was for speedy sold on leather or non-metal band.... but i am not really sure about his answer...should ask him again

 

I don't recall any plated speedmasters. Which one are you referring to?

 

Ooops

 

The 145.012-68 SP I recently acquired most definitely has a cal.321 movement.

 

From AJTT Appendix

 

Keep in mind Omega has added an extra "0" to the case number for the 321, so a 145012 is actually a 1450012 in the modern case number language - the complete case number is actually 055ST1450012. To make this even more confusing, the 861 case number is 1450122.

I don't know where you are looking up part numbers and case references, but even if that resource has these subtle changes included, you still have to know about them to get things straight. It can be confusing.

Yes this was the photo that got me worried....
145.012-68 SP is not mentioned here!

 

As has already been stated in this thread, the letter code that indicates case material is before the numbers, not after.

If yours is yellow gold capped, it would be a 055CD135020 - CD is the case material code. There is an "SP" version of all the case materials for this case, so there is an 055CD135020SP as well. The other case materials also come in the SP and non-SP versions, so for the pink gold capped (code CE), the stainless version (code ST), the 3N coloured 18k yellow gold version (code BB), and the 2N coloured yellow gold case (code BA).

The chart that has been posted and now reposted says what SP stands for - Special. It's not necessarily related to pushers IMO since many watches without pushers also have this code as you point out.

Cheers, Al

 

Yepp i now . It wasn't any real forensic science about my inlay in the thread . I just looked at the crowns and pushers you mentioned in this inlay .The 069ST43069 is for the 145.022 case . Maybe on the 145.012SP also ?
145012:

Case tube - 090ST0017

Crown - 069ST43018

145012SP:

Case tube - 090ST0005

Crown - 069ST43069

Cheers, Al

 

Of course parts can be used on different cases, as in this instance.

 

This is my 135.020 SP case . I was only asking if there where anything like that with the speedmaster cases .

 

My thought was ? It must be some sort of transfer time . 145.022 parts on a 145.012SP case . The 145.012SP has a 321 movement but uses 145.022 pushers and crowns ? Is this right ?

 

Sorry but I am not sure at all what you are asking, however the 1450012SP and the 1450022 do not use the same pushers...

 

I give up.

 

Read my thread and u understand what i mean.
