Hello all,

Any help on this model would appreciated

It's 35mm without crown

I can't find any information on this ref 2661

Best regards to all

Tuc

 

Does anyone have any idea about this reference number?

 

Hi Tuc,
maybe a variation of the 2608 model with the spider lugs....?
it is being offered at the moment on this site:
