Hi Guys
From Speedmaster 101
Mine is March 1970

Sorry, not correct. Just open your copy of Moonwatch Only and read.

Edit: Here is a selection from MWO. As you can see, the DON was used in the 145.022-69 until almost 30.6M. Honestly, this is quite well known. Just do some research.

Everything I’ve read indicates my watch should have DN90?
Thoughts anyone?

Your watch with 29.11M serial? It's not even close. I don't know what you are reading, but did you read the MWO excerpt I posted? You can also search for threads on the site. There are dozens of discussions of the DON/DNN transition in the 30.5M serial range.

You might want to share your sources? So we might help them to update the erroneous information they spread.

Thanks Kov and Dan for correcting that info. I’m no expert and can only believe what I read.

Hi Guys
As mentioned on another threat, I have an option to replace my poor condition 220 bezel, with a good original DN90 bezel, image attached.
Can I get opinions on this?

thanks

Con
I would never replace it until it's broken or completely faded. The 220 it's beautiful as it is showing its age and time

Kov I share the images above

Those seem to be from Fratello Watches, so I'm not sure why you mention Speedmaster 101. Indeed, if there is obsolete information on Speedmaster 101, please share a link, since I'm sure William would want to correct it.

Anyway, I think you are over-interpreting those images. They just suggest that transition occurred in approximately 1970, which is not wrong. But there is much more detail known and much more to read. Using the search function here is always a good idea.
