Steel Band for the Professional Moonwatch

Morning folks,
First time in.
Proud owner of two Speedmasters and love them both.
I purchased the sapphire sandwich with a leather band..Love Love Love it.
I did want to purchase the steel band.
I would like the Omega brand.
It is the one paired with the moonwatch in reference # 310.30.42.50.01.002

All I see is the description of "steel with five links with fold-over clasp and comfort setting"
What is the part number for this band?

Can this be gotten from Omega as a part or is this an AD item?

Thanks
Chris

Thank you.
I did not even realize there are two different ones!
I do have one on my Broad Arrow (few years older) but wanted to complete the set for the moonwatch pro

Any idea what I should expect to pay?

Or around £700 in the UK. Boutiques should have them in stock if you happen to be close to one.

got it! spoke to the folks where I bought the watch. 750.00 and they can order. Tks.
