I picked up this LNOS Vulcain chronograph a while back and always assumed it had a valjoux 7733. On seeing the movement now, I'm slightly perplexed. I've seen a few of these listed with a valjoux 7733 but this one looks a bit different. I suppose they could've been made with a variety of movements during their production run..

Any thoughts on what I have here?

Early one maybe, I still see some venus 188 simularity

 

Looks very much like a Valjoux 7734, but without a window for the date

I agree that it's in the Venus 188/Valjoux 7730/Valjoux 7733 family. Can you shine some light under the balance and get a photo?

 

Nice watch! Am lusting after a Cricket... one day...
