Hi folks,

Firstly, I tried to search the forum but couldn’t find info or I lack the knowledge to recognize the info I need so apologies if there is a thread

I have a 2813 BP Sea Dweller 16600 that I’m perfectly happy with except the need for the right frequency and setting direction which are incorrect due to 2813..

I found out that I cant fit a VR3135 in this 2813 case so I found the below offering from Trusty that says BP Sea dweller A3135.. now I couldnt find info on this A3135 movement. Is this an exact 3135 clone like a VR3135? Or just a decorated eta clone?

things I’m looking for are correct setting direction as VR3135 and 28800 bph so does anyone know if this A3135 has these or I still need to source a VR to have these features?

thanks!

The movement in it is a SA3135.
It’s not as reliable as a VR, but it has the correct beat rate and time setting.

If/when it fails, a VR will be a direct swap.

Many thanks bud! Think I’ll go with the A3135 then.. can you also confirm that I cant fit any 3135 clone in the 2813 BP SD case?

That is correct. You cannot put any A3135 in a case that is made for a 2813 or 2836. You can replace a 2824 with a 3135.

As the previous answers said:
There is a big difference between 28xx movements and SA/SH/VR/VS 3135 in terms of stem height and diameter.

Even if it would work, you need to take into account that for a movement type swap you may end up needing new set of hands and dial (as dial feet are different aligned)

If i should make a suggestion, i would say: live with it as it is or (in case you can’t) sell the one you have and buy the one you prefer afterwards.
