Hello!
To begin with, I wanted to agree with the participants who have already spoken in one form or another with the idea that your question is not correct, and in other sections of the forum, you can easily run into rudeness or ridicule if you put your questions in this form without understanding how this hobby and forum works.
On the merits of the matter; I assume you are looking for a supposedly submersible (Give PAM389 as an example), which is important to narrow things down, since 47mm has both luminors and radiomirs.Also, I take as a basis that you are looking for one of the models, the probability of getting it from TD is new (I doubt that you are ready to fish m2m for months).
If so, I would suggest a quick solution, such as PAM692.
This model has its drawbacks, and quite obvious to the experienced eye, like any rep pam, but you can read more about this in the thread of this model, and / or one of my posts.(Enter "pam692" in the search bar and be sure to wear these threads in the PANERAI section)
Other than that, I can say that depending on what you prefer in style (Unless your preference is limited to "as close to gen as possible"), almost any 47mm submersible VSF will do, almost equally.
