Did this ever originally come with a DN90?

 

Nope.

Early -69's also came with the DoN.

 

You don't start to see DNN bezels until you get into the 30M serials.

 

Dial looks nice though.

Judging by some recent threads, you might be able to get a reasonable contribution towards a DoN by selling this.

 

I can't tell if it's the glare from the crystal, but it also looks like this one might have an incorrect rehaut?

 

Ahh yes I remember changing the crystal and thus now looks like:

 

This one is 29M. 145.022-68ST

 

29 is a bit late for these, but not necessarily wrong. The DNN did not appear until later in the 145.022-69 production

 

29 million serial number is a 69, can't be a 68.
I have an early 29,100,xxx and it is a 69. DON

 

After rechecking an old photo, it's either a 280 or 290 serial. Hard to tell for sure but defintely one of those.

 

28xx is still too late for a 68

 

it is?

If you go by MWO and 101 chart http://speedmaster101.com/serial-quick-reference-to-78/ ?

Mines is 26 5x but maybe someone has a 28?

 

Ok this serial number issue has been vexing me so I decided to have my watchmaker open the case to confirm the number. It is indeed a 280x.
I also found a good DON 90 bezel to repatriate with this gem. I love its pristine dial .

 

28M serial should be fine, it probably indicates a 1969 production date - towards the end of production for these. (I have a 145.022-69 with a 28.42M movement that was produced on January 9, 1970.)

 

I assume it has DO90?

 

Yes

 

in fact, it appears to be listed for sale just recently.

 

Sho is!

 

What do you guys think a 145.022-68st like mine would run in the current market esp with DON90?
