This watch does not manually wind and the main chronograph hand gets stuck and doesn't function properly.  Besides that the watch will run and keep good time.  

The band and deployant clasp are authentic Breitling, and they are very worn.  The clasp is stainless steel and can be polished to look like new, if desired. 

The diameter of the case, not including the crown, is apx. 39mm. 

Please look at the pictures and feel free to ask questions. 

Thank you.
