5513 project - Alternatives on low-beat movements

[McDown 2]

Hi guys,

Hope this is the right area to post (if not - please point me in the right direction :)). Got a very nice 5513 off on RWI a few years back that I’m considering upgrading a bit. The case set it Ruby’s with a MoChaCha dial installed on a TY2130-movement, but considering it’s a high-beat I’m thinking about swapping it out for a low-beat one. It would be great to get some guidance on whether there are any low-beat movements with the same dimensions as the TY2130 and fits the Ruby case and MoChaCha dial. If you know - please feel free to reply to this thread of shoot me a PM  

Best,
