u/Best-Replacement-867

I have an old Breitling Navitimer issued to pilots in the Algerian air force in the 80s(?) I think.

It looks awesome but sadly, it's not currently working - the battery acid leaked and so it will apparently need a new movement which is not an easy prospect.

Either way, I want to sell it - can anyone advise me on where would be best to do this?

I have no box, papers or bracelet links
