Tudor Prince Oysterdate sizes

[dentaku]

Hi,
I'm a total beginner with Tudor and Rolex but I've seen some nice Prince Oyster Dates and I'm confused over the sizes.

One is being sold as a 9081 'Jumbo' and said to be 38mm. I've seen another one which looks identical but the seller says it's 36mm (both excl crown) -- I don't know the model number of this one but the bracelet has 282 end pieces.

I'm aware of 34mm models, but what about 36 and 38mm? Are they the same thing, with measuring inaccuracies?

Also, should the case back on these have a circular 'satin' finish, or polished? Both are 'Oyster case by Rolex' backs.

Any help and advice much appreciated!

Gentle bump in case anyone has any information :)

I'm not sure about the 36mm but there were the Jumbo and regular as you described and there was also a mid-size (some call it boy's size) at around 31mm.
